The network device 110 provides communication coverage to a specific geographical area, and communicates with the terminal device in the coverage area.

FIG. 1 illustrates one network device and two terminal devices. In some embodiments, the communication system 100 includes a plurality of network devices, and each network devices covers other number of terminal devices, which is not limited in the embodiments of the present disclosure.

In some embodiments, the communication system 100 further includes a network controller, a mobile management entity, or other network entities, which is not limited in the embodiments of the present disclosure.

It should be noted that devices with the communication function in the network/system in the embodiments of the present disclosure are referred to as communication devices. By taking the communication system 100 shown in FIG. 1 as an example, the communication device includes the network device 110 and the terminal device 120 that have the communication function, and the network device 110 and the terminal device 120 are specific devices described above, which are not repeater herein. The communication device further includes other devices in the communication system 100, for example, the network controller, the mobile management entity, or other network entities, which is not limited in the embodiments of the present disclosure.

It should be understood that the terms “system” and “network” herein are interchangeably used. The term “and/or” herein describes an association relationship between associated objects, and indicates three types of relationships. For example, the phrase “A and/or B” means (A), (B), or (A and B). In addition, the symbol “/” generally indicates an “or” relationship between the associated objects.

It should be understood that the term “indicate” in the embodiments of the present disclosure means a direct indication, an indirect indication, or an indication that there is an associated relationship. For example, A indicating B means that A indicates B directly, e.g., B may be acquired by A; or that A indicates B indirectly, e.g., A indicates C by which B may be acquired; or that an association is present between A and B.

In the description of the embodiments of the present disclosure, the term “corresponding” mean that there is a direct correspondence or indirect correspondence between two objects, an association relationship between two objects, an indicating and being indicated relationship, or a configuring and being configured relationship.

In the embodiments of the present disclosure, the “predefinition” is achieved by pre-storing corresponding codes or forms in the device (for example, including the terminal device and the network device) or other means for indicating relevant information, and the specific implementations are not limited in the present disclosure. For example, the predefinition is defined in the protocol.

In the embodiments of the present disclosure, the “protocol” indicates standard protocols in the field of communications, for example, the LTE protocol, the NR protocol, and related protocols applied to the future communication system, which are not limited in the present disclosure.

In the NR system, the network device allocates the uplink resources based on the granularity of the terminal device (per-UE), and the terminal device determines data of which wireless bearer can be placed in the allocated uplink resources for transmission.

Based on the uplink resource configured by the network device, the terminal device requires to determine an amount of data transmitted over each LCH in a fronthaul medium access control protocol data unit (MAC PDU). In some cases, the terminal device further requires to allocate resources to a MAC control element (MAC CE). It is necessary to allocate a priority to each LCH to multiplex the LCH. For a MAC PDU with a determined size, in the case that a plurality of LCHs simultaneously have data transmission requirements, resources for transmission of the MAC PDU are allocated based on a descending order of priorities corresponding to uplink LCHs.

A prioritized bit rate (PBR) is introduced to balance fairness of various LCHs. In the case that the terminal device multiplexes the LCHs, a minimum data rate requirement of each LCH is first met to avoid a case that other LCHs with lower priorities of the terminal device are “starved” as the LCHs with higher priorities always occupy the uplink resources allocated by the network device to the terminal device.

To multiplex the LCHs, the network device configures the following parameters by radio resource control (RRC) signaling:

• • the priority of the LCH, the smaller a value of the priority, the higher the corresponding priority;
  • the PBR, indicating a minimum rate required by the LCH; and
  • a bucket size duration (BSD), determining a depth of a token bucket corresponding to the LCH.

A MAC layer of the terminal device multiplexes the LCHs using a token bucket mechanism.

Specifically, the terminal device maintains a variable Bj for each LCH j, and the variable indicates a number of current available tokens in the token bucket corresponding to the LCH. The number of tokens is set by the following methods:

• • (1) Bj is initialized to 0 when the terminal device establishes the LCH j;
  • (2) PBR*T is added to Bj prior to each logical channel prioritization (LCP) processing process by the terminal device, wherein T is an interval from a previous time of adding Bj to a current time; and
  • (3) Bj is set as a maximum volume of the token bucket in the case that Bj updated in step (2) is greater than a maximum volume of the token bucket (that is, PBR*BSD).

In the case that the terminal receives a newly transmitted uplink (UL) grant, the terminal performs the LCP processing by the following processes.

In S1, for all LCHs with Bj is greater than 0, resources are allocated based on a descending order of priorities, and the resource allocated to each LCH only meets a PBR requirement. That is, the resource is allocated to the LCH based on the number of tokens in a PBR token bucket corresponding to the LCH. In some embodiments, in the case that a PBR of an LCH is set to infinity, other LCHs with lower priorities than the LCH are considered only when the resource of the LCH is met.

In S2, a size of the LCH j multiplexed by all MAC service data units (SDUs) in the MAC PDU in S1 is subtracted from Bj.

In S3, in the case that there are remaining uplink resources upon S1 and S2, the remaining uplink resources are sequentially allocated to various LCHs based on the descending order of priorities of the LCHs no matter the size of Bj. Data of the LCHs with lower priorities is transmitted only when the data of the LCHs with higher priorities is transmitted and the UL grants are not exhausted. That is, the terminal device maximizes data transmission on the LCHs with higher priorities.

Meanwhile, the MAC layer of the terminal device follows the following principles in packetization:

• • 1. a radio link control (RLC) SDU should not be segmented in the case that the RLC SDU can be padded in the remaining resources;
  • 2. a maximum segment is padded as possible based on the size of the remaining resources in the case that the terminal device segments the RLC SDU in the LCH;
  • 3. the terminal device should maximize transmission of the data; and
  • 4. the UE should not only transmit a padding buffer status report (BSR) or only transmit the padding in the case that the UL grant size is greater than or equal to 8 bytes.

For different signals and/or LCHs, in performing the LCP processing, the terminal device should also follow the following priority order (a descending order of priorities):

• • a cell radio network temporary identity (C-RNTI) MAC CE or data from an uplink common control channel (UL-CCCH);
  • a configured grant confirmation MAC CE;
  • a BSR MAC CE used in addition to the padding BSR;
  • a single entry power headroom report (PHR) MAC CE or a multiple entry PHR MAC CE;
  • data from any LCH in addition to the UL-CCCH;
  • a MAC CE used for a recommended bit rate query; and
  • a BSR MAC CE used for the padding BSR.

With the development of the technologies, support of the communication system on the vertical industries is wider and deeper. Communication services include services in vertical industries, and such services may have different transmission requirements, for example, a quality of service (QOS) requirement and/or importance. Thus, how to process and transmit such services is an urgent problem to be solved. For example, an ultra-reliable and low delay communication (URLLC) requirement supports transmission of factory automation, transport industry, electrical power distribution, and other services in the NR system. An XR requirement supports transmission of AR, VR, cloud gaming, and other services. These services have requirements on the reliability and the delay. Thus, in the case that resources for these services are scheduled for the terminal device, the resources should meet the QoS requirement of the service transmission. A power consumption is also considered for the terminal device to avoid unnecessary power consumption. Meanwhile, for the network device, considering an access problem of a large number of terminal devices supporting the services, a requirement of a network capacity should be met in allocating resources.

As an example, the URLLC requirement or the XR requirement supports a service with requirements of at least 0.5 ms and the 99.999% reliability. The service is pseudo-periodic (that is, an arrival time of the service is jitter, that is, the service arrives not at a fixed time but at any time in a range). Meanwhile, the service period may be a non-integer period, for example, 16.67 ms. In addition, arrival times of different service streams of the same service may differ from each other greatly (for example, for the AR service, an UL pose period is 4 ms, but an UL video period is 16.67 ms).

For the AR service, the VR service, or the cloud gaming service, possible service models are as follows:

• • AR: UL pose information, a UL video stream, and a downlink (DL) video stream;
  • VR: UL pose information and a DL video stream; and
  • cloud gaming: UL control information and a DL video stream.

A period of the control information or the pose information is about 4 ms, a requirement of a packet size is about 100 bytes. A period of the video stream is about 16.67 ms, and a requirement of a packet size is about 0.67 Mbps.

In actual applications, different media units have different QoS requirements and/or importance. For example, for a video, the QoS requirement or the importance of an intra-coded picture frame (I frame) is greater than that of a predictive-coded picture frame (P frame). QoS requirements and/or importance of service streams or QoS streams of different media units are different.

Thus, for services with different QoS requirements and/or importance, how to appropriately process the services to improve a system capacity, avoid resource wasting, and ensure transmission of services with a high QoS requirement and/or high importance is an urgent problem to be solved.

For convenient understanding of the technical solutions according to the embodiments of the present disclosure, the technical solutions of the present disclosure are described in detail by detailed embodiments hereinafter. The following related technologies as optional solutions may be arbitrarily combined with the technical solutions according to the embodiments of the present disclosure, and fall within the scope of protection of the embodiments of the present disclosure. The embodiments of the present disclosure include at least some of the following contents, which is beneficial to meeting requirements of services with different QoS requirements and/or importance.

FIG. 2 is a schematic diagram of a method 200 for wireless communication according to some embodiments of the present disclosure. As shown in FIG. 2, the method 200 includes at least some of the following processes.

In S210, a terminal device performs a processing operation on data based on transmission requirement information of the data.

The terminal device processes the data based on the transmission requirement information of the data, such that transmission requirements of various data are met.

In some embodiments, the data includes to-be-processed data and/or to-be-transmitted data.

For example, the data includes data in a buffer of the terminal device and/or data submitted to a lower layer of the terminal device.

In some embodiments, the buffer of the terminal device includes a Packet Data Convergence Protocol (PDCP) buffer and/or a RLC buffer.

In some embodiments, the lower layer of the terminal device incudes a RLC layer and/or a MAC layer.

In some embodiments, the data includes a media unit or a data packet corresponding to a media unit. That is, the data includes the media unit, or the data includes partial data in the media unit.

In some embodiments, the media unit includes, but is not limited to, any of an application layer data packet, an application data unit (ADU), a frame, a coded slice, or the like of the terminal device. In some embodiments, the media unit may include a set of application layer data packets, ADUs, frames or coded slices; or the media unit may include a plurality of application layer data packets, a plurality of ADUs, a plurality of frames, or a plurality of coded slices.

In some embodiments, the data is a control packet or a data packet. The control packet is configured to carry control information, and the data packet is configured to carry data information.

In some embodiments, the data is an I frame or coded slice, a P frame or coded slice, or a bidirectionally predicted picture frame (B frame) or coded slice.

In some embodiments, the transmission requirement information of the data includes any parameter related to data transmission.

By way of example but not limitation, the transmission requirement information of the data includes at least one of: a QoS requirement of the data, importance of the data, a QoS requirement of a path of the data, or importance of a path of the data.

In some embodiments, the path of the data includes a QoS stream to which the data is mapped, a radio bearer to which the data is mapped, a PDCP layer to which the data is mapped, an RLC layer to which the data is mapped, a MAC layer to which the data is mapped, a carrier to which the data is mapped, or a hybrid automatic repeat request (HARQ) process to which the data is mapped.

In some embodiments, the importance of the data is defined based on a type of the data. For example, the control packet and the data packet correspond to different importance. The importance of the control packet is higher than the importance of the data packet. For example, the I frame or coded slice, the P frame or coded slice, and B frame or coded slice correspond to different importance. The importance of the I frame or coded slice is higher than the importance of the P frame or coded slice and the importance of the B frame or coded slice. Alternatively, the importance of the data is determined based on a priority instruction of the data. For example, data with a lower priority instruction value corresponds to higher importance, data with a higher priority instruction value corresponds to lower importance, or the like.

In some embodiments, the processing operation includes, but is not limited to resource scheduling and/or resource allocation, or QoS mapping or assurance.

In some embodiments, the processing operation includes, but is not limited to a processing operation of the MAC layer.

In some embodiments, the processing operation includes, but is not limited to at least one of: LCP processing, MAC PDU packetization, LCH mapping using an LCP mapping restriction, or resource selection (that is, resource allocation) using an LCP mapping restriction.

In some embodiments, the terminal device performs different processing operations on data with a specific transmission requirement and data with a non-specific transmission requirement.

In some embodiments, a QoS requirement and/or importance of the data with the specific transmission requirement is higher than a QoS requirement and/or importance of the data with the non-specific transmission requirement.

In some embodiments, the data with the specific transmission requirement includes at least one of: data with a high QoS requirement, data with high importance, data with a QoS requirement higher than a first QoS threshold, data with importance higher than a first importance threshold, or data carrying a specific identifier.

In some embodiments, the data with the non-specific transmission requirement includes at least one of: data with a low QoS requirement, data with low importance, data with a QoS requirement lower than the first QoS threshold, data with importance lower than the first importance threshold, or data not carrying a specific identifier.

In some embodiments, the data includes identifier information indicating the type of the data, such as the control packet or the data packet; the I frame, the P frame or the B frame; an important type or a non-important type; or indicating a value of the priority, or the like.

In some embodiments, the data carrying the specific identifier includes at least one of: data carrying a control packet identifier, data carrying an I frame identifier, a data packet carrying an importance type identifier, or a packet carrying a high priority identifier.

In some embodiments of the present disclosure, the terminal device determines the data with the specific transmission requirement as a high-prioritized data packet, or determines a HARQ process corresponding to the data with the specific transmission requirement as a prioritized HARQ process, or determines uplink grant corresponding to the data with the specific transmission requirement as a prioritized uplink grant, or determines downlink grant corresponding to the data with the specific transmission requirement as a prioritized downlink grant, or determines a carrier corresponding to the data with the specific transmission requirement as a prioritized carrier.

In some embodiments of the present disclosure, the terminal device determines the data with the non-specific transmission requirement as a low-prioritized data packet, or determines a HARQ process corresponding to the data with the non-specific transmission requirement as a low-prioritized HARQ process, or determines uplink grant corresponding to the data with the non-specific transmission requirement as a low-prioritized uplink grant, or determines downlink grant corresponding to the data with the non-specific transmission requirement as a low-prioritized downlink grant, or determines a carrier corresponding to the data with the non-specific transmission requirement as a low-prioritized carrier.

In some embodiments, the HARQ process corresponding to the data with the specific transmission requirement refers to a HARQ process used in transmitting the data with the specific transmission requirement, the uplink grant corresponding to the data with the specific transmission requirement refers to uplink grant used in transmitting the data with the specific transmission requirement, the downlink grant corresponding to the data with the specific transmission requirement refers to downlink grant used in transmitting the data with the specific transmission requirement, and the carrier corresponding to the data with the specific transmission requirement refers to a carrier used in transmitting the data with the specific transmission requirement.

In some embodiments, the MAC of the terminal device determines, based on a mapping relationship between any of a data radio bearer (DRB), an LCH, the HARQ process or the uplink grant and the data, whether the DRB, the LCH, the HARQ process, or the uplink grant corresponds to the data with the specific transmission requirement, or determines, based on identifier information of the data corresponding to the DRB, the LCH, the HARQ process, or the uplink grant, whether the DRB, the LCH, the HARQ process, or the uplink grant corresponds to the data with the specific transmission requirement. For example, in the case that a DRB corresponds to an identifier of prioritized data, the DRB corresponds to the data with the specific transmission requirement. In some embodiments, the identifier of the prioritized data includes, but is not limited to the control packet identifier, the I frame identifier, the importance type identifier, and the high priority identifier. For example, in the case that a DRB corresponds to the identifier of the prioritized data, and a HARQ process carries the DRB, the HARQ process is a process corresponding to the specific transmission requirement, and the HARQ process corresponds to the data with the specific transmission requirement.

That is, in that case that the data is transmitted over the resource, which DRB or the LCH for prioritized processing is determined based on whether the DRB or the LCH has a mapping relationship with high-prioritized data, or whether the DRB or the LCH is configured with the identifier of the prioritized data. For example, in that case that a first DRB or a first LCH has a mapping relationship with high-prioritized data, or a first DRB or a first LCH is configured with the identifier of the prioritized data, the first DRB or the first LCH is processed with priority. For example, in that case that a first DRB or a first LCH has a mapping relationship with high-prioritized data, or a first DRB or a first LCH is configured with the identifier of the prioritized data, the HARQ process or the grant of the first DRB or the first LCH is processed with priority. In some embodiments, which HARQ process or the uplink grant for prioritized processing, or data for prioritized transmission corresponding to which HARQ process or the uplink grant is determined based on whether the HARQ process or the uplink grant has a mapping relationship with high-prioritized data, or whether the HARQ process or the uplink grant is configured with the identifier of the prioritized data. For example, in the case that a first HARQ process or a first uplink grant has a mapping relationship with high-prioritized data, or a first HARQ process or a first uplink grant is configured with the identifier of the prioritized data, data corresponding to the first HARQ process or the first uplink grant is transmitted with priority. Detailed implementations of processing the data based on the transmission requirement information of the data by the terminal device are described hereinafter in conjunction detailed embodiments.

In some embodiments, the second processing operation includes, but is not limited to at least one of: performing LCP processing on the data using a second LCP rule; packetizing the data using a second MAC packetization mode; or performing LCH mapping and/or resource selection on the data using a second LCH mapping restriction.

That is, the parameters corresponding to the second processing operation include parameters corresponding to the second LCP rule, and/or parameters corresponding to the second MAC packetization mode, and/or parameters corresponding to the second LCH mapping restriction.

In some embodiments, the transmission requirement of the data is met by processing the data with the non-specific transmission requirement using the second LCP rule, using the second MAC packetization mode, or using the second LCH mapping restriction.

In some embodiments, the parameters corresponding to the second processing operation include at least one of: a priority, a PBR, a BSD, or a second LCH mapping restriction.

In some embodiments, the first configuration information further includes a first correspondence indicating a correspondence between at least one of a DRB, an LCH, or a PDCP layer and the transmission requirement information of the data.

For example, the first correspondence is a correspondence of the DRB and the QoS requirement or the importance, a correspondence of the LCH and the QoS requirement or the importance, or a correspondence of the PDCP layer and the QoS requirement or the importance.

Thus, the terminal device maps the data with different QoS requirements or importance to different DRBs, LCHs, or PDCP layers based on the first correspondence, such that the data with different QoS requirements or importance is processed appropriately, and the transmission of the data with the high QoS requirement or high importance is ensured.

In some embodiments, the first configuration information further includes first parameter information indicating transmission requirement parameters of data associated with at least one of the DRB, the LCH, or the PDCP layer.

For example, the first parameter information includes a QoS requirement parameter or an importance parameter associated with the DRB, and/or a QoS requirement parameter or an importance parameter associated with the LCH, and/or a QoS requirement parameter or an importance parameter associated with the PDCP layer.

Thus, the terminal determines the QoS requirement or the importance that can be met by the DRB, the LCH, or the PDCP layer based on the first parameter information, and further maps the data with different QoS requirements or importance to different DRBs, LCHs, or PDCP layers, such that the data with different QoS requirements or importance is processed appropriately, and the data with the high QoS requirement or high importance is transmitted.

That is, the terminal device configures the QoS requirement or importance corresponding to the DRB, the LCH, or the PDCP layer, or configures QoS requirement related parameters or importance related parameters corresponding to the DRB, the LCH, or the PDCP layer, such that the terminal device determines the QoS requirement or the importance that can be met by the DRB, the LCH, or the PDCP layer based on the QoS requirement related parameters or the importance related parameters, and further performs appropriate mapping on the data based on the QoS requirement or the importance of the data.

In some embodiments, the first configuration information further includes first indication information indicating whether to activate the first LCH parameters, or whether to enable the first processing operation. For example, the first indication information indicates whether to enable the first LCP rule, whether to enable the first MAC packetization mode, or whether to enable the first LCH mapping restriction.

In some embodiments, in the case that the first indication information instructs to activate the first LCH parameters or to enable the first processing operation, the terminal device processes the data with the specific transmission requirement based on the first LCH parameters, or performs the first processing operation on the data with the specific transmission requirement.

In some embodiments, in the case that the first indication information instructs to deactivate the first LCH parameters or to disable the first processing operation, the terminal device processes the data with the specific transmission requirement based on the second LCH parameters, or performs the second processing operation on the data with the specific transmission requirement.

In some embodiments, the first indication information and the above LCH parameters are configured by a same signaling, or by different signaling. For example, the first indication information is transmitted by the downlink control information (DCI) or the MAC CE.

In some embodiments, the first LCH parameter, the first processing operation, the second LCH parameter, or the second processing operation is used based on a duration. The duration corresponding to a timer.

In some embodiments, the first configuration information further includes a first duration indicating a using or enabling duration of the first LCH parameters or the first processing operation. For example, the first LCH parameter or the first processing operation is used within the first duration, and the first LCH parameter or the first processing operation is not used or the second LCH parameter or the second processing operation is used upon run-out of the first duration.

In some embodiments, the first duration is configured by the network device, for example, configured by the first configuration information, configured by single signaling, predefined, that is, without indication of the network device, or determined by the terminal device.

In some embodiments, the first configuration information further includes a second duration indicating a using or enabling duration of the second LCH parameters or the second processing operation. For example, the second LCH parameter or the second processing operation is used within the second duration, and the second LCH parameter or the second processing operation is not used or the first LCH parameter or the first processing operation is used upon run-out of the second duration.

In some embodiments, the second duration is configured by the network device, for example, configured by the first configuration information, configured by single signaling, predefined, that is, without indication of the network device, or determined by the terminal device.

In some embodiments, the first configuration information further includes a third duration indicating a disabling or non-use duration of the first LCH parameters or the first processing operation. For example, the first LCH parameter or the first processing operation is not used within the third duration, and the first LCH parameter or the first processing operation is used or the second LCH parameter or the second processing operation is not used upon run-out of the third duration.

In some embodiments, the third duration is configured by the network device, for example, configured by the first configuration information, configured by single signaling, predefined, that is, without indication of the network device, or determined by the terminal device.

In some embodiments, the first configuration information further includes a fourth duration indicating an non-use or disabling duration of the second LCH parameters or the second processing operation. For example, the second LCH parameter or the second processing operation is not used within the fourth duration, and the second LCH parameter or the second processing operation is used or the first LCH parameter or the first processing operation is not used upon run-out of the fourth duration.

In some embodiments, the fourth duration is configured by the network device, for example, configured by the first configuration information, configured by single signaling, predefined, that is, without indication of the network device, or determined by the terminal device.

In some embodiments, the first duration is equal to the fourth duration.

In some embodiments, the second duration is equal to the third duration.

In some embodiments, the data is acquired by a first layer of the terminal device from a higher layer of the terminal device, and the higher layer of the terminal device is above the first layer.

In some embodiments, the first layer of the terminal device includes, but is not limited to at least one of: a Service Data Adaptation Protocol (SDAP) layer, a PDCP layer, or a MAC layer.

In some embodiments, the first layer of the terminal device determines whether the data is the data with the specific transmission requirement upon acquiring the data.

In some embodiments, the first layer of the terminal device determines whether the data is the data with the specific transmission requirement based on indication of the higher layer of the terminal device, or self-determines whether the data is the data with the specific transmission requirement.

In some embodiments, the first layer of the terminal device determines to perform the first processing operation in the case that the data is the data with the specific transmission requirement. In some embodiments, the first layer of the terminal device transmits second indication information to the MAC layer of the terminal device. The second indication information indicates that the data is the data with the specific transmission requirement, or the second indication information is designed to instruct to perform the first processing operation.

In some embodiments, the first layer of the terminal device further determines to perform the second processing operation in the case that the data is the data with the non-specific transmission requirement. In some embodiments, the first layer of the terminal device transmits third indication information to the MAC layer of the terminal device. The third indication information indicates that the data is the data with the non-specific transmission requirement, or the third indication information is designed to instruct to perform the second processing operation.

In some embodiments, in the case that the data is the data with the specific transmission requirement, the terminal device transmits indication information to the network device to indicate that the data with the specific transmission requirement is present or instruct the network device to adjust the first configuration information. Furthermore, the network device determines that the data with the specific transmission requirement is present based on the indication information or determines to adjust the LCH parameters to ensure the transmission requirement of the data with the specific transmission requirement. For example, in the case that the network device does not configure the first LCH parameters for the terminal device, the network device configures the first LCH parameters for the terminal device in the case that the network device receives the indication information from the terminal device. Alternatively, in the case that the network device has configured the first LCH parameters for the terminal device, the network device instructs to activate the first LCH parameters based on the first indication information.

In some embodiments, the first processing operation is activated by default, self-activated by the terminal device, activated based on a condition (that is, the terminal device performs the first processing operation on the data in a specific condition), activated periodically, or activated in response to the first LCH parameters being configured.

In some embodiments, the terminal device performs the first processing operation on the data in response to a first condition being met.

For example, in the case that the first condition is met, the MAC layer of the terminal device performs the first processing operation on the data.

In some embodiments, the first condition includes, but is not limited to at least one of:

• • the MAC layer of the terminal device receives the second indication information from the first layer of the terminal device;
  • a buffer of the terminal device contains data with a specific transmission requirement; transmission of the data with the specific transmission requirement is not completed;
  • a quantity of available resources is less than an amount of the data with the specific transmission requirement;
  • LCH parameters corresponding to the data with the specific transmission requirement are not matched with the amount of the data with the specific transmission requirement;
  • currently used LCH parameters are not matched with the amount of the data with the specific transmission requirement;
  • a transmission delay of the data with the specific transmission requirement is greater than a first delay threshold;
  • a transmission delay of data with a non-specific transmission requirement is greater than a second delay threshold;
  • a duration of disabling the first processing operation reaches a third duration; or
  • a duration of enabling a second processing operation reaches a second duration.

In some embodiments, in the case that the first condition is met, the terminal device performs the LCP processing or the MAC PDU packetization using the first LCP rule, using the first MAC packetization mode, or using the first LCH mapping restriction, and further transmit the data.

In some embodiments, that the buffer of the terminal device contains the data with the specific transmission requirement includes at least one of: the data with the specific transmission requirement is not transmitted, or the data with the specific transmission requirement is not processed.

In some embodiments, that the data with the specific transmission requirement is not processed includes at least one of: the LCP processing is not performed on the data with the specific transmission requirement, the MAC PDU packetization is not performed on the data with the specific transmission requirement, the LCH mapping is not performed on the data with the specific transmission requirement, or the resource allocation is not performed on the data with the specific transmission requirement.

In some embodiments, that the transmission of the data with the specific transmission requirement is not completed includes at least one of: the buffer of the terminal device contains the data with the specific transmission requirement, or the data with the specific transmission requirement that is not transmitted is present in the lower layer of the terminal device, or the data with the specific transmission requirement that is transmitted improperly is present in the terminal device, or the data with the specific transmission requirement for which a positive acknowledgement (ACK) is not received is present in the terminal device.

In some embodiments, in the case that the size of the available resource is less than the amount of the data with the specific transmission requirement, the LCP processing or the MAC PDU packetization is performed on the data based on the first processing operation, such that the resource is allocated with priority to the data with the specific transmission requirement, and the transmission of the data with the specific transmission requirement is ensured.

In some embodiments, that the LCH parameters corresponding to the data with the specific transmission requirement are not matched with the amount of the data with the specific transmission requirement includes at least one of: the first configuration information only includes the second LCH parameters, but a token bucket size of the LCH configured based on the second LCH parameters is less than the amount of the data with the specific transmission requirement; or the first configuration information includes the first LCH parameters, but a token bucket size of the LCH configured based on the first LCH parameters is less than the amount of the data with the specific transmission requirement. In some embodiments, the currently used LCH parameters refer to the second LCH parameters in the case that the first configuration information only includes the second LCH parameters, or refer to the first LCH parameters or the second LCH parameters in the case that the first configuration information includes the first LCH parameters and the second LCH parameters.

In some embodiments, that the currently used LCH parameters are not matched with the amount of the data with the specific transmission requirement includes: a token bucket size of the LCH configured based on the currently used LCH parameters is less than the amount of the data with the specific transmission requirement.

In some embodiments, the transmission delay of the data with the specific transmission requirement being greater than the first delay threshold means that a remaining transmission time of the data with the specific transmission requirement is less, and thus the data with the specific transmission requirement is transmitted with priority to meet a delay requirement of the data.

In some embodiments, the transmission delay of the data refers to a duration from a start time of the data transmission to a time at which the data is transmitted to the opposite end or is successfully received by the opposite end (for example, the ACK from the opposite end is received).

In some embodiments, the start time of the data refers to a time at which the data arrives or is stored in the buffer of the terminal device, a time at which the data is generated, a time at which the data arrives at an air interface, a time at which the data arrives at the PDCP layer, or a start time at which the data is transmitted in the lower layer of the terminal device.

For example, the transmission delay of the data is a duration from generation of the data to reception of the data by the opposite end, or a duration from arrival of the data to the PDCP layer to successful reception of the data by the opposite end. For example, a duration in which the data is transmitted by the lower layer of the terminal device but feedback information from the opposite end is not received is construed as the transmission delay of the data, a duration consumed by transmission, or a part of the transmission delay.

In some embodiments, the first delay threshold is predefined, configured by the network device, for example, configured in the first configuration information, or determined by the terminal device.

In some embodiments, the first delay threshold is a packet delay budget (PDB).

In some embodiments, the transmission delay of the data with the non-specific transmission requirement being greater than the second delay threshold means that a remaining transmission time of the data with the non-specific transmission requirement is less. That is, the delay requirement is not met even if the data with the non-specific transmission requirement is transmitted immediately. Thus, the data with the specific transmission requirement is transmitted with priority to meet the delay requirement of the data with the specific transmission requirement.

In some embodiments, the second delay threshold is predefined, configured by the network device, for example, configured in the first configuration information, or determined by the terminal device.

In some embodiments, the second delay threshold is a PDB.

In some embodiments, the terminal device enables or disables the first processing operation periodically, or enables or disables the first LCH parameters periodically.

For example, for periodically disabling the first processing operation, a timer is periodically started, and a duration of the timer is a third duration. The first processing operation is disabled during running of the timer, and the first processing operation is enabled in response to expiration of the timer. Furthermore, the second processing operation is disabled in response to enabling of the first processing operation.

In some embodiments, periodically enabling or disabling the first processing operation based on the timer is applicable to periodically transmitted data.

In some embodiments, the terminal device enables or disables the second processing operation periodically, or enables or disables the second LCH parameters periodically.

For example, for periodically enabling the second processing operation, a timer is periodically started, and a duration of the timer is a second duration. The second processing operation is disabled upon expiration of the timer. Furthermore, the first processing operation is enabled in response to the second processing operation being disabled.

In some embodiments, performing, by the terminal device, the first processing operation on the data in response to the first condition being met includes:

• • modifying a second LCH mapping restriction, and performing the LCH mapping and/or the resource selection on the data using the modified second LCH mapping restriction, wherein the second LCH mapping restriction is configured for the data with the non-specific transmission requirement; or
  • performing the LCH mapping and/or the resource selection on the data using the first LCH mapping restriction, wherein the first LCH mapping restriction is configured for the data with the specific transmission requirement.

For example, in the case that the first configuration information only includes parameters corresponding to the second LCH mapping restriction, and the first condition is met, the terminal device modifies the second LCH mapping restriction, and performs the LCH mapping and/or the resource selection on the data with the specific transmission requirement based on the modified second LCH mapping restriction.

For example, in the case that the first configuration information includes parameters corresponding to the first LCH mapping restriction, and the first condition is met, the terminal device performs the LCH mapping and/or the resource selection on the data with the specific transmission requirement based on the first LCH mapping restriction.

In some embodiments, the modified second LCH mapping restriction includes that only the LCH corresponding to the data with the specific transmission requirement is allowed to be mapped onto the first resource in the case that a plurality of LCHs are to be mapped onto the first resource, and a first LCH in the plurality of LCHs is the LCH corresponding to the data with the specific transmission requirement.

Thus, in the case that the resource selection is performed based on the modified second LCH mapping restriction, the resource is allocated with priority to the data with the specific transmission requirement, and thus the data with the specific transmission requirement is transmitted with priority.

In some embodiments, the first LCH mapping restriction includes that only the LCH corresponding to the data with the specific transmission requirement is allowed to be mapped onto the first resource in the case that a plurality of LCHs are to be mapped onto the first resource, and a first LCH in the plurality of LCHs is the LCH corresponding to the data with the specific transmission requirement.

Thus, in the case that the resource selection is performed based on the first LCH mapping restriction, the resource is allocated with priority to the data with the specific transmission requirement, and thus the data with the specific transmission requirement is transmitted with priority.

In some embodiments, performing the first processing operation on the data in response to the first condition being met includes:

• • modifying a second LCP rule, and performing the LCP processing on the data using the modified second LCP rule, such that an uplink grant resource includes the data, wherein the second LCP rule is configured for data with a non-specific transmission requirement; or
  • performing the LCP processing on the data using the first LCP rule, such that an uplink grant resource includes the data, wherein the first LCP rule is configured for data with a specific transmission requirement.

For example, in the case that the first configuration information only includes parameters corresponding to the second LCP rule, and the first condition is met, the second LCP rule is modified, and the LCP processing is performed on the data with the specific transmission requirement based on the modified second LCP rule.

For example, in the case that the first configuration information includes parameters corresponding to the first LCP rule, and the first condition is met, the LCP processing is performed on the data with the specific transmission requirement based on the first LCP rule.

In some embodiments, modifying the second LCP rule includes modifying the token bucket size and/or a PBR of an LCH corresponding to the data, or modifying a mapping relationship between the LCH and the resource.

In some embodiments, modifying the token bucket size of the LCH corresponding to the data includes: increasing the token bucket size of the LCH corresponding to the data with the specific transmission requirement, or setting the token bucket size of the LCH corresponding to the data with the specific transmission requirement as infinity.

For example, the terminal device temporarily modifies the token bucket size of at least one LCH corresponding to the ADU to ensure the ADU associated with the at least one LCH to be multiplexed with priority.

In some embodiments, modifying the PBR of the LCH corresponding to the data includes: increasing the PBR of the LCH corresponding to the data with the specific transmission requirement, or setting the PBR of the LCH corresponding to the data with the specific transmission requirement as infinity.

For example, the terminal device temporarily modifies the PBR of at least one LCH corresponding to the ADU as infinity to ensure the ADU associated with the at least one LCH to be multiplexed with priority.

In some embodiments, the modified mapping relationship between the LCH and the resource includes that the LCH corresponding to the data with the specific transmission requirement is mapped with priority onto the first resource in the case that a plurality of LCHs are to be mapped onto the first resource, and a first LCH in the plurality of LCHs is the LCH corresponding to the data with the specific transmission requirement.

In some embodiments, the first LCP rule includes at least one of: the token bucket size of the LCH corresponding to the data with the specific transmission requirement is infinite; or the LCH corresponding to the data with the specific transmission requirement is mapped with priority onto the first resource in the case that a plurality of LCHs are to be mapped onto the first resource, and a first LCH in the plurality of LCHs is the LCH corresponding to the data with the specific transmission requirement.

In some embodiments, performing the first processing operation on the data in response to the first condition being met includes:

• • modifying a second MAC packetization mode, and packetizing the data using the modified second MAC packetization mode, such that an uplink grant resource includes the data; or
  • packetizing the data using the first MAC packetization mode, such that an uplink grant resource includes the data.

For example, in the case that the first configuration information only includes parameters corresponding to the second MAC packetization mode, and the first condition is met, the second MAC packetization mode is modified, and the packetization is performed on the data with the specific transmission requirement based on the modified second MAC packetization mode.

For example, in the case that the first configuration information includes parameters corresponding to the first MAC packetization mode, and the first condition is met, the packetization is performed on the data with the specific transmission requirement using the first MAC packetization mode.

In some embodiments, the modified second MAC packetization mode or the first MAC packetization mode includes that the data with the specific transmission requirement is multiplexed with priority in the uplink grant resource. That is, the data with the specific transmission requirement is packeted with priority.

For example, in the case that the second LCP rule is not modified, the data with the specific transmission requirement is multiplexed in the uplink grant resource to transmit with priority using the first MAC packetization mode or the modified second MAC packetization mode.

In some embodiments, the second processing operation is activated by default, activated based on a condition, activated in the case that the first LCH parameters are not configured, deactivated in the case that the first LCH parameters are configured, or activated periodically.

In some embodiments of the present disclosure, S210 includes:

• • performing a second processing operation on the data in response to a second condition being met.

For example, the MAC layer of the terminal device performs the second processing operation on the data in response to the second condition being met.

In some embodiments, the second condition includes, but is not limited to at least one of:

• • the MAC layer of the terminal device receives third indication information from the first layer of the terminal device, wherein the third indication information indicates that the data is the data with the non-specific transmission requirement, or the third indication information is designed to instruct to perform the second processing operation;

  • the transmission of the data with the specific transmission requirement is completed; the size of the available resource is greater than or equal to the amount of the data with the specific transmission requirement;

  • a duration of enabling the first processing operation reaches a first duration;
  • a duration of disabling the second processing operation reaches a fourth duration; or
  • an amount of to-be-transmitted data with the specific transmission requirement is less than a first amount threshold.

In some embodiments, that the buffer of the terminal device contains no data with the specific transmission requirement includes at least one of: the transmission of the data with the specific transmission requirement is completed, the processing of the data with the specific transmission requirement is completed, for example, the LCP processing is performed on the data with the specific transmission requirement, the ACK feedback of the data with the specific transmission requirement is received, the MAC PDU packetization is performed on the data with the specific transmission requirement, or the LCH mapping or the resource allocation is performed on the data with the specific transmission requirement.

In some embodiments, that the transmission of the data with the specific transmission requirement is completed includes: no data with the specific transmission requirement that is not transmitted is present in the lower layer of the terminal device, no data with the specific transmission requirement that is transmitted improperly is present in the terminal device, or no data with the specific transmission requirement for which the ACK is not received is present in the terminal device.

In some embodiments, the size of the available resource being greater than or equal to the amount of the data with the specific transmission requirement means that the available resource is sufficient. In this case, the second processing operation is performed on the data, such that the data with the specific transmission requirement is allocated with the sufficient resource to some extent, and the transmission requirement of the data with the specific transmission requirement is met.

In some embodiments, that the LCH parameters corresponding to the data with the specific transmission requirement are matched with the amount of the data with the specific transmission requirement includes: the first configuration information only includes the second LCH parameters, and the token bucket size of the LCH configured based on the second LCH parameters is greater than or equal to the amount of the data with the specific transmission requirement; or the first configuration information includes the first LCH parameters, and the token bucket size of the LCH configured based on the first LCH parameters is greater than or equal to the amount of the data with the specific transmission requirement.

In some embodiments, that the transmission delay of the data with the specific transmission requirement is less than or equal to the first delay threshold means that the remaining transmission time of the data with the specific transmission requirement is more. Thus, the second processing operation is performed on the data, and the delay requirement of the data with the specific transmission requirement is met to some extent.

In some embodiments, that the amount of the to-be-transmitted data with the specific transmission requirement is less than the first amount threshold means that the to-be-transmitted data with the specific transmission requirement is less, and thus the transmission requirement of the data with the specific transmission requirement is met to some extent by performing the second processing operation.

In some embodiments, the terminal device enables or disables the first processing operation periodically.

For example, for periodically enabling the first processing operation, a timer is periodically started, and a duration of the timer is a first duration. The first processing operation is disabled in response to expiration of the timer. Furthermore, the second processing operation is enabled in response to disabling of the first processing operation.

In some embodiments, the third duration is predefined, configured by the network device, or determined by the terminal device.

In some embodiments, that the first processing operation is enabled or disabled based on the timer is applicable to periodically transmitted data.

In some embodiments, the terminal device enables or disables the second processing operation periodically.

For example, for periodically disabling the second processing operation, a timer is periodically started, and a duration of the timer is a fourth duration. The second processing operation is disabled in the running of the timer, and the second processing operation is enabled in response to expiration of the timer. Furthermore, the first processing operation is disabled in response to enabling of the second processing operation.

In some embodiments, the fourth duration is predefined, configured by the network device, or determined by the terminal device.

In conjunction with FIG. 3, the whole process of the above first embodiments is illustrated. As shown in FIG. 3, the whole process includes at least some of the following processes.

In S211, a network device transmits first configuration information to a terminal device. For detailed descriptions of the first configuration information, reference may be made to related descriptions of the above embodiments, which are not described herein.

For example, the LCP processing process is performed based the first LCP rule, the MAC PDU packetization is performed using the first MAC packetization mode, or the like.

In S213, the terminal device transmits a packeted MAC PDU to the network device.

In summary, in the first embodiments, the terminal device performs different processing operations on the data in different conditions. For example, the data is processed based on the first processing operation in the case that there is the data with the high QoS requirement or high importance, and the data is processed based on the second processing operation without the data with the high QoS requirement or high importance, such that the data with the high QoS requirement or high importance is processed or transmitted with priority.

Alternatively, the first CG resource is associated with the data with the specific transmission requirement, or the first CG resource is only configured to transmit the data with the specific transmission requirement.

In some embodiments, the terminal device self-activates the first CG resource, or activates the first CG resource based on the condition.

In some embodiments, the terminal device activates the first CG resource in the case that the network device configures the first CG resource configuration.

In some embodiments of the present disclosure, the method 200 further includes:

• • receiving, by the terminal device, third configuration information from the network device, wherein the third configuration information includes second LCH parameters.

For detailed implementations of the second LCH parameters, reference may be made to related descriptions in the first embodiments, which are not described herein.

For example, the second correspondence is a correspondence of the DRB and the QoS requirement or the importance, a correspondence of the LCH and the QoS requirement or the importance, or a correspondence of the PDCP layer and the QoS requirement or the importance.

Thus, the terminal device determines the QoS requirement or the importance that can be met by the DRB, the LCH, or the PDCP layer based on the second correspondence, and thus maps the data with different QoS requirements or importance to corresponding DRBs, LCHs, or PDCP layers, such that the QoS requirement or the importance of the data is met.

For the case that the buffer of the terminal device includes the data with the specific transmission requirement, reference may be made to related descriptions in the first embodiments, which are not described herein for brevity.

For the case that the transmission of the data with the specific transmission requirement is not completed, reference may be made to related descriptions in the first embodiments, which are not described herein for brevity.

In some embodiments, the amount of the data in the buffer of the terminal device being greater than the third amount threshold indicates that the amount in the buffer is excessive great. In this case, the third processing operation is performed, such that the data with the specific transmission requirement is processed or transmitted with priority.

In some embodiments, the size of the available resource being less than the amount of the data with the specific transmission requirement means that the available resource is not sufficient. Thus, the third processing operation is performed, such that the data with the specific transmission requirement is transmitted with priority.

In some embodiments, the third amount threshold is predefined, configured by the network device, for example, configured in the third configuration information, or determined by the terminal device.

In some embodiments, that the LCH parameters corresponding to the data with the specific transmission requirement are not matched with the amount of the data with the specific transmission requirement includes the token bucket size of the LCH configured based on the second LCH parameters is less than the amount of the data with the specific transmission requirement.

In some embodiments, the currently used LCH parameters are LCH parameters configured by the network device, for example, the second LCH parameters.

In some embodiments, that the currently used LCH parameters are not matched with the amount of the data with the specific transmission requirement includes: the token bucket size of the LCH configured based on the second LCH parameters is less than the amount of the data with the specific transmission requirement.

In some embodiments, the transmission delay of the data with the specific transmission requirement being greater than the fifth delay threshold means that a remaining transmission time of the data with the specific transmission requirement is less. In this case, the third processing operation is performed, such that the data with the specific transmission requirement is transmitted with priority to meet the delay requirement of the data.

In some embodiments, the fifth delay threshold is predefined, configured by the network device, for example, configured in the third configuration information, or determined by the terminal device.

In some embodiments, the transmission delay of the data with the non-specific transmission requirement being greater than the sixth delay threshold means that a remaining transmission time of the data with the non-specific transmission requirement is less. That is, the delay requirement is not met even if the data with the non-specific transmission requirement is transmitted immediately. Thus, the third processing operation is performed to ensure the transmission of the data with the specific transmission requirement is prioritized.

In some embodiments, the sixth delay threshold is predefined, configured by the network device, for example, configured in the third configuration information, or determined by the terminal device.

In some embodiments, the PDB requirement of the data with the specific transmission requirement being higher than the first PDB threshold means that a delay tolerance of the data is low. In this case, the third processing operation is performed to ensure the priority transmission of the data with the specific transmission requirement.

In some embodiments, the first PDB threshold is predefined, configured by the network device, for example, configured in the third configuration information, or determined by the terminal device.

In some embodiments, the amount of the data with the non-specific transmission requirement being greater than the fourth amount threshold means that a space occupied by the data with the non-specific transmission requirement is large. In this case, the third processing operation is performed to ensure the priority transmission of the data with the specific transmission requirement.

In some embodiments, the fourth amount threshold is predefined, configured by the network device, for example, configured in the third configuration information, or determined by the terminal device.

It should be understood that the buffer delay of the data indicates a duration of occupying the buffer by the data. For example, the data is in the PDCP buffer or the RLC buffer, and the lower layer of the PDCP layer does not transmit the data. Alternatively, the data is in the PDCP buffer or the RLC buffer, and the lower layer of the PDCP layer has not successfully transmitted the data. Alternatively, the data is in the PDCP buffer or the RLC buffer, and the terminal device has not received the ACK of the data. Alternatively, the data is still in the PDCP buffer or the RLC buffer.

As described above, the transmission delay of the data refers to a duration from a start time of the data to a time at which the data is transmitted to the opposite end or is successfully received by the opposite end (for example, receives the ACK from the opposite end).

In some embodiments, the start time of the data refers to a time at which the data arrives or is stored in the buffer of the terminal device, or a time at which the data is generated, or a time at which the data arrives an air interface, or a time at which the data reaches the PDCP layer, or a start time at which the data is transmitted in the lower layer of the terminal device.

For example, the transmission delay of the data is a duration from generation of the data to reception of the data by the opposite end, or a duration from arrival of the data to the PDCP layer to successful reception of the data by the opposite end. For example, a duration in which the data is transmitted by the lower layer of the terminal device but feedback information of the opposite end is not received is construed as the transmission delay of the data, or a duration consumed by transmission, or a part of the transmission delay.

It should be understood that in the case that an application layer of the terminal device is considered, the buffer delay of data and the transmission delay of data is described in terms of the application layer of the terminal device. Alternatively, in the case that a non-access layer (NAS) of the terminal device is considered, the buffer delay of data and the transmission delay of data is described in terms of the application layer of the terminal device.

In some embodiments, the buffer delay of the data with the specific transmission requirement being greater than the seventh delay threshold means that a duration of occupying the buffer by the data is great. In this case, the third processing operation is performed to ensure the priority transmission of the data with the specific transmission requirement.

In some embodiments, the seventh delay threshold is predefined, or configured by the network device, for example, configured in the third configuration information, or determined by the terminal device.

In some embodiments, the buffer amount of the data refers to an amount of the data in the PDCP buffer or the RLC layer.

It should be understood that in the case that an application layer of the terminal device is considered, the buffer amount of the data is described in terms of the application layer of the terminal device, and the amount of the data is described in terms of the lower layer of the terminal device. Alternatively, in the case that the NAS of the terminal device is considered, the buffer amount of the data is described in terms of the application layer of the terminal device, and the amount of the data is described in terms of an access layer (AS) of the terminal device.

In some embodiments, the buffer amount of the data with the specific transmission requirement being greater than the fifth amount threshold means that the amount of the data with the specific transmission requirement in the PDCP buffer or the RLC layer is greater. In this case, the third processing operation is performed to ensure the priority transmission of the data with the specific transmission requirement.

In some embodiments, the fifth amount threshold is predefined, or configured by the network device, for example, configured in the third configuration information, or determined by the terminal device.

In conjunction with FIG. 5, the whole process of the above third embodiments is illustrated. As shown in FIG. 5, the whole process includes at least some of the following processes.

In S231, a network device transmits third configuration information to a terminal device. For detailed descriptions of the third configuration information, reference may be made to related descriptions of the above embodiments, which are not described herein.

In S232, the terminal device performs a third processing operation in response to a fifth condition being met.

Upon the third processing operation being performed, the LCP processing and/or the MAC PDU packetization is performed on the data based on the second LCH parameters.

In S233, the terminal device transmits a packeted MAC PDU to the network device.

In summary, in the second embodiments, the terminal device performs different processing operations on the data in different conditions.

For example, the third processing operation is performed in the case that the fifth condition is met, and the processed data is further processed based on the second LCH parameters, such that the data with the high QoS requirement or high importance is processed or transmitted with priority.

In summary, the terminal device performs the first processing operation on the data based on the transmission requirement information of the data, such that the processing or transmission of the data with the specific transmission requirement is prioritized. Alternatively, the terminal device activates the first CG resource based on the transmission requirement information of the data, and the first CG resource is configured to transmit the data with the specific transmission requirement or is associated with the LCH corresponding to the data with the specific transmission requirement, which is equivalent to increment of the resource for transmitting the data with the specific transmission requirement, such that the transmission requirement of the data is facilitate to be met. Alternatively, the terminal device performs the third processing operation based on the transmission requirement information of the data, for example, deleting the data with the non-specific transmission requirement in the buffer, or the like, such that the priority processing or transmission of the data with the specific transmission requirement is ensured.

In the first embodiments, the UE uses the first LCP rule, or performs the first MAC packetization mode, or uses the first LCH mapping restriction based on the QoS requirement or the importance of the media unit. The first embodiments are more applicable to a case of mapping media units/streams with different QoS requirements or importance to different DRBs/LCHs/PDCPs.

Detailed implementation processes are as follows (by taking the uplink as an example).

In S1, a UE receives RRC configuration parameters configured by a network.

In some embodiments, the RRC configuration parameters include the LCH configuration parameters.

In some embodiments, the LCH configuration parameters s include priority, prioritisedBitRate, bucketSizeDuration, and the LCH mapping restriction (for example, CG allowing LCH mapping, DG allowing LCH mapping).

In some embodiments, the RRC configuration parameters include more than one set of LCH configuration parameters. A set of LCH configuration parameters are parameters corresponding to the first LCP rule, the first MAC packetization mode, or the first LCH mapping restriction (another set of LCH configuration parameters includes parameters for normal transmission).

In some embodiments, the parameters corresponding to the first LCP rule, the first MAC packetization mode, or the first LCH mapping restriction are determined by the UE.

In some embodiments, the parameters corresponding to the first LCP rule, the first MAC packetization mode, or the first LCH mapping restriction are configured to ensure the priority transmission or processing of the media unit with the specific QoS requirement or importance or the data packet corresponding to the media unit.

In some embodiments, the RRC configuration parameters include corresponding information or indication information of the DRB/LCH/PDCP and the media units with different (or specific) QoS requirements or importance, or parameters or information of different QoS requirements or importance of the media units for the DRB/LCH/PDCP.

In some embodiments, the RRC configuration parameters include indication information indicating whether to enable the first LCP rule, whether to perform the first MAC packetization mode, or whether to use the first LCH mapping restriction. In some embodiments, the indication information is indicated to the UE in the DCI/MAC CE.

In S2, the UE acquires a data packet from a higher layer.

In some embodiments, a first layer of the UE determines, based on the indication of the higher layer or self-detection of the UE, whether the data packet is the media unit with the specific QoS requirement or importance or the data packet corresponding to the media unit.

In some embodiments, the first layer is one of the SDAP, the PDCP, and the MAC.

In some embodiments, the first layer of the UE informs the MAC layer of the UE of the determined information, or the first layer instructs the MAC layer of the UE to use the first LCP rule, or perform the first MAC packetization, or use the first LCH mapping restriction.

In some embodiments, the “specific” indicates the high QoS requirement or importance, the QoS requirement or importance greater than a threshold, or carries a specific identifier.

In S3, the UE performs the LCP/MAC PDU packetization and transmits the packet.

In some embodiments, an entity for performing S3 is a MAC entity of the UE.

In some embodiments, in the case that the first condition is met, the UE uses the first LCP rule, or performs the first MAC packetization, or performs the LCP/MAC PDU packetization by using the first LCH mapping restriction, and transmits the packet.

  • the size of the available resource is less than the amount of the media unit with the specific QoS requirement or importance or the data packet corresponding to the media unit;
  • LCH parameters corresponding to the media unit with the specific QoS requirement or importance or the data packet corresponding to the media unit are not matched with the amount of the media unit with the specific QoS requirement or importance or the data packet corresponding to the media unit. For example, the token bucket size of the LCH is less than the amount of the media unit with the specific QoS requirement or importance or the data packet corresponding to the media unit;
  • a transmission delay of the media unit with the specific QoS requirement or importance or the data packet corresponding to the media unit is greater than the first delay threshold (and thus is ensured with priority); or
  • a transmission delay of the media unit with the non-specific QoS requirement or importance or the data packet corresponding to the media unit is greater than the first delay threshold (and thus is ensured with low priority, and it is no matter in the case of being lost).

In some embodiments, the first LCP rule, the first MAC packetization mode, or the first LCH mapping restriction is one of: modifying the LCH mapping restriction or using the A set of LCH mapping restriction.

In the case that a plurality of LCHs may be mapped to a resource, and one of the plurality of LCHs is an LCH corresponding to the media unit with the specific QoS requirement or importance or the data packet corresponding to the media unit. In this case, only the LCH corresponding to the media unit with the specific QoS requirement or importance or the data packet corresponding to the media unit is allowed to be mapped onto the resource.

In some embodiments, the LCP process or the PDU packetization process is modified, or the A set of LCH mapping restriction is used, such that the media unit with the non-specific QoS requirement or importance or the data packet corresponding to the media unit is included in the allocated grant.

For example, the UE temporarily modifies the token bucket size of the LCH/LCH group/LCH set corresponding to the ADU, such that the associated ADU is multiplexed with priority. For example, the prioritisedBitRate is set as infinity.

In some embodiments, the token bucket size is not modified, but the UE multiplex with priority the data of the associated ADU to the grant.

In some embodiments, in the case that the second condition is met, the UE performs normal transmission, or performs the LCP/MAC PDU packetization based on the RRC configuration parameters (non-A set), and transmits the packet.

In some embodiments, the second condition includes at least one of:

• • the indication information of the first layer of the UE is acquired, and indicates the media unit with the non-specific QoS requirement or importance or the data packet corresponding to the media unit;
  • the media unit with the specific QoS requirement or importance or the data packet corresponding to the media unit is not present, or the transmission of the media unit with the specific QoS requirement or importance or the data packet corresponding to the media unit is completed;
  • the size of the available resource is greater than or equal to the amount of the media unit with the specific QoS requirement or importance or the data packet corresponding to the media unit;
  • the LCH parameters corresponding to the media unit with the specific QoS requirement or importance or the data packet corresponding to the media unit are matched with the amount of the media unit with the specific QoS requirement or importance or the data packet corresponding to the media unit.

  • a duration of using the first LCP rule, performing the first MAC packetization mode, or using the first LCH mapping restriction reaches a first duration;

  • a to-be-transmitted amount of the media unit with the specific QoS requirement or importance or the data packet corresponding to the media unit is less than a threshold.

In some embodiments, in the case that the UE determines whether the packet is the packet corresponding to the media unit with the specific QoS requirement or importance or the data packet corresponding to the media unit, the UE reports the indication information to a base station, but does not use the first LCP rule, or perform the first MAC packetization mode, or use the first LCH mapping restriction. The first indication information is configured for the network to determine that the media unit with the specific QoS requirement or importance or the data packet corresponding to the media unit is present, or configured to assist the network to adjust the RRC configuration parameters, and configured to ensure transmission or the prioritized transmission of the media unit with the specific QoS requirement or importance or the data packet corresponding to the media unit.

The technical effects of the first embodiments are that the LCP rule is modified for a specific media unit to ensure the processing of the service with the priority or the high QoS requirement is prioritized.

In the second embodiments, the UE activates the first CG resource based on the QoS requirement or the importance of the media unit. The first CG resource is configured to transmit the media unit with the specific QoS requirement or importance or the data packet/LCH corresponding to the media unit.

In some embodiments, the second embodiments are applicable to a case of mapping media units/streams with different QoS requirements or importance to different DRBs/LCHs/PDCPs, and/or a case of mapping media units/streams with the same QoS requirement or importance to different DRBs/LCHs/PDCPs.

In some embodiments, the first layer of the UE informs the MAC layer of the UE of the determined information, or the first layer instructs the MAC layer of the UE to activate the first CG resource.

In S3, the UE transmits the data packet using an uplink resource.

In some embodiments, an entity for performing S3 is the MAC of the UE.

In some embodiments, an initial state of the first CG resource is a deactivated state.

  • the size of the available resource is less than the amount of the media unit with the specific QoS requirement or importance or the data packet corresponding to the media unit;
  • the LCH parameters corresponding to the media unit with the specific QoS requirement or importance or the data packet corresponding to the media unit are not matched with the amount of the media unit with the specific QoS requirement or importance or the data packet corresponding to the media unit. For example, the token bucket size of the LCH is less than the amount of the media unit with the specific QoS requirement or importance or the data packet corresponding to the media unit;
  • the transmission delay of the media unit with the specific QoS requirement or importance or the data packet corresponding to the media unit is greater than a threshold (and thus is ensured with priority); or

In some embodiments, in the case that the first CG resource is activated, the UE transmits the media unit with the specific QoS requirement or importance or the data packet/LCH corresponding to the media unit using the first CG resource, such that an available transmission resource of a specific media unit is increased.

In some embodiments, the UE deactivates the first CG resource in the case that the fourth condition is met.
