Apparently, the accompanying drawings in the following description show merely some embodiments of the present disclosure, and those of ordinary skill in the art may still derive other drawings from these accompanying drawings without creative efforts.
For clearer descriptions of the objectives, technical solutions, and advantages of the present disclosure, embodiments of the present disclosure are further described in detail hereinafter with reference to the accompanying drawings.
First, the terms involved in the embodiments of the present disclosure are described.
Extended reality (XR): XR is a huge platform providing extensive supports and coverage for a plurality of heterogeneous use cases and services, studied and summarized in working groups of SA1, SA2, and SA4, including but not limited to TR 22.842 and TR 26.928. For example, an XR use case includes augmented reality (AR), virtual reality (VR), and mixed reality (MR).
Extended reality and media services (XRM): XRM includes XR (extended reality) services and media services.
Video slice: A video slice is a spatially different region in a video frame, which is coded separately from another region in the same frame.
Packet data unit set (PDU set): A PDU set includes one or more PDUs that bear an effective payload of one information unit generated in an application layer. For example, the information unit is a frame or a video slice of XRM. The information has the same importance requirements in the application layer. In the application layer, all the PDUs in the PDU set are required to use the corresponding information unit. In some cases, the application layer is still capable of restoring part of the information unit in the case that some of the PDUs are lost. It should be noted that I-frames, P-frames, and the like mentioned hereinafter represent only a form of the PDU set.
An I-frame is an intra-coded picture, and is a complete picture that may be independently encoded and decoded like a JPG image file.
An P-frame is a predictive picture, but is not a complete frame and only contains image changes as compared with a previous frame. In the case that a reference frame is lost, the P-frame cannot be decoded or displayed.
A B-frame is a bi-predictive picture, and contains changes between a previous reference frame and a later reference frame. The more reference frames, the higher a compression ratio. However, the B-frame may only be decoded in the case that a previous reference frame and a later reference frame are available.
Group of pictures (GOP): A GOP includes a set of consecutive video frames. The first frame of the GOP is an I-frame, and a following frame may be a P-frame or a B-frame.
5G network system architecture: With reference to
The control plane function includes: an access and mobility management function (AMF), a session management function (SMF), a policy control function (PCF), a unified data management (UDM) function, an application function (AF), a network slice selection function (NSSF), and an authentication server function (AUSF).
The UE is connected via an access stratum to the AN over a Uu air interface to exchange access stratum messages and perform wireless data transmission, and the UE is connected via a non-access stratum (NAS) to the AMF over an N1 interface to exchange NAS messages. The AMF is a mobility management function in a core network, the SMF is a session management function in the core network, and the AMF is responsible for forwarding messages related to session management between the UE and the SMF in addition to performing mobility management on the UE. The PCF is a policy management function in the core network, and is responsible for formulating policies related to mobility management, session management, billing, and the like, on the UE. The UPF is a user plane function in the core network, and performs data transmission with an external data network over an N6 interface and with the AN over an N3 interface.
In the future, 3GPP systems is expected to increasingly extensively and deeply support vertical industries. For example, the URLLC supports requirements for transmission of services, such as factory automation, transport automation, and electrical power distribution, in a 5G system. The XR supports requirements for transmission of services such as augmented reality (AR)/virtual reality (VR)/cloud gaming (CG). These services imposes a common requirement for reliability and latency, as the services are required to satisfy a requirement on quality of service (QOS) for data transmission when resource scheduling is performed for UE. For the UE, a requirement on UE power consumption further needs to be satisfied, so as to avoid unnecessary power consumption. In addition, as a large number of UEs supporting the services may access the network, a requirement for ensuring network capacity further needs be satisfied during resource allocation.
For example, for the URLLC/XR, there is a need to support services requiring a minimum of 0.5 ms and 99, 999% reliability. The services may be pseudo-periodic, that is, jitter exists in the service arrival time. To be specific, the services do not arrive at a specific time point but at any moment within a range. In addition, a service period may be a non-integer period, for example, 16.67 ms. Further, arrival times of different service flows of the same service may differ significantly. For example, for the AR, a UL pose period is 4 ms, but a UL video period is 16.67 ms.
For the services such as the AR/VR/cloud gaming, possible service models are as follows.
A period of the control information or the pose information is about 4 ms and a packet size requirement is about 100 bytes. A period of the video streams is about 16.67 ms, and a packet size requirement is about 0.67 Mbps.
Further, each service is pseudo-periodic, that is, the service arrives periodically. However, there is jitter in a time point at which the service arrives during each period, that is, the service arrives within a time range.
In particular, for the AR, in uplink transmission, pose information and video stream information are included in one period, and the two streams arrive at different times.
In particular, for the XR services, a data packet size is variable.
Characteristics of the XR services are as follows:
A terminal enables a serving base station to acquire an uplink buffer data volume of the UE over the BSR, such that the base station can schedule the UE based on data volume information provided by the terminal. To save BSR reporting overheads, group reporting is adopted. Each uplink logical channel (LCH) corresponds to one logical channel group (LCG), a plurality of uplink logical channels may correspond to the same LCG, and a corresponding relationship between an LCH and an LCG is configured by a network over radio resource control (RRC). For example, the terminal reports the BSR based on the LCG. In new radio (NR), each terminal is capable of supporting up to eight LCGs.
For example, conditions for triggering the BSR include the following items.
In the case that a plurality of logical channels simultaneously trigger regular BSRs, each of the plurality of logical channels triggers one single regular BSR.
In some embodiments, the BSR MAC CE is used to bear the BSR. Reporting content and forms of BSR are classified into the following four types:
In the foregoing 4 forms of BSRs:
With respect to regular BSRs and periodic BSRs:
With respect to padding BSRs:
In NR, as in long-term evolution (LTE), a network allocates an uplink transmission resource on a per-terminal (per-UE) basis, rather than on a per-bearer basis, and the UE determines a radio bearer of which data can be put into the allocated uplink transmission resource for transmission.
Based on an uplink transmission resource configured by a network, the UE needs to determine a data volume to be transmitted on each logical channel in a medium access control packet data unit (MAC PDU) for initial transmission, and in some cases, the UE needs to allocate a resource to a MAC CE.
In some embodiments, to achieve multiplexing of an uplink logical channel, a priority needs to be assigned to each uplink logical channel. For a MAC PDU of a given size, in the case that a plurality of uplink logical channels simultaneously need to transmit data, resources of the MAC PDU are sequentially allocated in a descending order of logical channel priorities corresponding to the plurality of uplink logical channels. In addition, for further ensuring equity among different logical channels, a probability of a prioritized bit rate (PBR) is introduced. In the case that the UE multiplexes logical channels, a minimum data rate requirement of each of the logical channels needs to be satisfied first, thereby avoiding a case where other uplink logical channels of a low priority of the UE are “starved to death” because an uplink logical channel of a high priority occupies, all along, uplink resources allocated to the UE by the network.
For example, to achieve multiplexing of the uplink logical channels, network RRC configures the following parameters for each of the uplink logical channels:
The MAC of the UE uses the token bucket mechanism to achieve uplink logical channel multiplexing.
The UE maintains a variable Bj for each uplink logical channel j, wherein the variable indicates a quantity of currently available tokens in the token bucket, and the method includes the following processes:
In some embodiments, in the case that the UE receives an uplink grant (UL grant) indicating new transmission, the UE performs logical channel prioritization processing with the following processes:
Process 1: For all logical channels with Bj>0, resources are allocated in a descending priority order from high to low, wherein a resource allocated to each of the logical channels only satisfies a PBR requirement, that is, the resource is allocated to the logical channel based on a quantity of tokens in a PBR token bucket corresponding to the logical channel. In the case that a PBR of a specific logical channel is set to infinity, a logical channel of a lower priority than the logical channel is considered only in the case that a resource requirement of the logical channel is satisfied.
Process 2: The size of all MAC service data units (SDUs) multiplexed into a MAC PDU in process 1 of the logical channel j is subtracted from Bj.
Process 3: In the case that there are remaining uplink resources after processes 1 and 2 are performed, the remaining resources are sequentially allocated to the logical channels in a descending logical channel priority order from high to low regardless of the size of Bj. The logical channel with lower priority can be served only in the case that data on a logical channel of a high priority is all transmitted and the uplink grant is not exhausted. That is, in this case, the UE maximizes data transmission for the logical channel of a high priority.
In addition, the UE should observe the following principles:
For example, for different signals and/or logical channels, the UE further needs to follow the following priority order (in a descending priority order from high to low) when logical channel prioritization processing is performed:

In some embodiments, the network allocates, based on the report, more PUSCH resources to transmit remaining data, or transmit important data, or transmit data with a high transmission latency requirement/a small remaining PDB/a short remaining latency. In some embodiments, in the case that a PUSCH resource currently scheduled over DCI is sufficient, the UE does not need to trigger and/or report the information.
In NR, the terminal needs to determine, based on an uplink transmission resource configured by the network device, a transmitted data volume on each logical channel in a MAC PDU for initial transmission. In some embodiments, the terminal further needs to allocate a resource to a MAC CE. To achieve multiplexing of an uplink logical channel, a priority needs to be assigned to each uplink logical channel.
In process 602, a MAC PDU is generated during an LCP procedure.
In some embodiments, before the LCP procedure is performed, the terminal needs to receive an uplink grant (UL grant), for new transmission, from a network device.

In some embodiments, the method for transmitting information according to the embodiments of the present disclosure further includes:
In some embodiments, in the LCP procedure, a first PDU is prioritized, or a first PDU set is prioritized, or an LCH priority is prioritized. Specific implementations are as follows.
In the LCP procedure, the first PDU is prioritized, or an LCH corresponding to the first PDU is prioritized, or data corresponding to the first PDU is preferentially put into the MAC PDU, or the priority of an LCH or an LCH group corresponding to the first PDU is adjusted to a high priority, or the first PDU set is prioritized, or an LCH corresponding to the first PDU set is prioritized, or data corresponding to the first PDU set is preferentially put into the MAC PDU, or the priority of an LCH in the MAC PDU or the LCP procedure is adjusted, or the priority of an LCH or an LCH group corresponding to the first PDU set is adjusted to a high priority.

The first PDU set is a specified PDU set and/or an associated PDU set; and the first PDU is a specified PDU or a specified data packet. In some embodiments, the specified PDU set is a data packet with a third identifier, or the specified PDU set is a first data packet; or the specified PDU is a data packet with a third identifier, or the specified PDU is a first data packet. The third identifier is one of an importance identifier, a priority identifier, or a latency value.

For example, the first data packet is a specific data packet. The specific data packet is one of data packets of importance or prioritization, data packets with a high latency requirement, with a small PSDB, with a latency or a remaining latency less than a threshold, with a small latency or a remaining latency (less than others, other LCHs, or other LCHs of the same priority), with a small PSDB or a PSDB less than a threshold, with a latency greater than a threshold 1 and less than a threshold 2, or data packets that do not satisfy or are about to fail satisfying the PSDB requirement.
In the embodiments of the present disclosure, at least one of a PSDB, a latency, a remaining PSDB, or a remaining latency is determined by MAC or a PDCP through statistics. The MAC or the PDCP determines at least one of the PSDB, the latency, the remaining PSDB, or the remaining latency based on a first duration or a first timer.
In some embodiments, the first duration or the first timer is started in the case that a data packet or a data packet of a PDU set arrives, is stored, or is available.

For descriptions related to the latency in the embodiments of the present disclosure, reference may be made to the foregoing content. The details are not described herein any further.
In some embodiments, in the LCP procedure, a quantity of available tokens in a token bucket corresponding to a logical channel further needs to be considered, specifically as follows.
In the LCP procedure, the size of a PDU set corresponding to a first logical channel is prioritized before a first variable is subtracted from the size of the MAC PDU, or the size of a first associated PDU set corresponding to a first logical channel is prioritized before a first variable is subtracted from the size of the MAC PDU; or
The first variable indicates the quantity of available tokens in a token bucket corresponding to the first logical channel, the second variable indicates the quantity of available tokens in a token bucket corresponding to the second logical channel, the first logical channel is a logical channel corresponding to a specified PDU set, and the second logical channel is a logical channel corresponding to an associated PDU set.

With reference to
In some embodiments, the method for transmitting information according to the embodiments of the present disclosure further includes:
Based on the foregoing content, taking a logical channel j as an example, in the case that an uplink grant indicating new transmission is received, the terminal performs logical channel prioritization processing based on the following processes.
Process 1: For all logical channels with Bj>0, resources are allocated in a descending priority order from high to low, wherein a resource allocated to each logical channel can only satisfy a PBR requirement, that is, the resource is allocated to the logical channel based on a quantity of tokens in a PBR token bucket corresponding to the logical channel. In the case that a PBR of a specific logical channel is set to infinity, only when a resource requirement of the logical channel is satisfied, a logical channel of a lower priority than the logical channel is considered.
Process 2: The size of all MAC SDUs multiplexed into a MAC PDU in process 1 of the logical channel j is subtracted from Bj.
Process 3: The size of data, in a PDU set in the logical channel j, multiplexed into the MAC PDU is determined, and the size of remaining data in the PDU set in the logical channel j is determined. The size of the remaining data in the PDU set in the logical channel j is subtracted from Bj.
Process 4: In the case that there are remaining uplink resources after processes 1 to 3 are performed, the remaining resources are sequentially allocated to each logical channel in a descending logical channel priority order from high to low regardless of the size of Bj. Only in the case that data on a logical channel of a high priority is all transmitted and the uplink grant is not exhausted, the logical channel with lower priority can be served. That is, in this case, the terminal maximizes data transmission for the logical channel of a high priority.
In some embodiments, the method for transmitting information according to the embodiments of the present disclosure further includes:
In some embodiments, the size of a MAC service data unit (MAC SDU) multiplexed into the MAC PDU in a fourth logical channel is subtracted from a fourth variable.
In some embodiments, the resource is allocated to the at least one logical channel based on a result acquired by subtracting the size of a PDU or a PDU set that has been allocated to a logical channel from the quantity of tokens in a token bucket corresponding to the logical channel.
Based on the foregoing content, still taking a logical channel j as an example, in the case that an uplink grant indicating new transmission is received, the terminal performs logical channel prioritization processing based on the following processes.
Process 1: For all logical channels with Bj>0, resources are allocated in a descending priority order from high to low, wherein a resource allocated to each logical channel can only satisfy a PDU set requirement, that is, the resource is allocated to the logical channel based on the size of a PDU set corresponding to the logical channel. The size of all MAC SDUs multiplexed into a MAC PDU in this process of the logical channel j is subtracted from Bj.
Process 2: For all logical channels with Bj>0, resources are allocated in a descending priority order from high to low, wherein a resource allocated to each logical channel can only satisfy a PBR requirement, that is, the resource is allocated to the logical channel based on the quantity of tokens in a PBR token bucket corresponding to the logical channel, or the resource is allocated to the logical channel based on a result acquired by subtracting the size of the PDU set allocated to the logical channel in process 1 from the quantity of tokens in a PBR token bucket corresponding to the logical channel. In the case that a PBR of a specific logical channel is set to infinity, only when a resource requirement of the logical channel is satisfied, a logical channel of a lower priority than the logical channel is considered.
Process 3: The size of all MAC SDUs multiplexed into a MAC PDU in process 2 of the logical channel j is subtracted from Bj.
Process 4: In the case that there are remaining uplink resources after processes 1 to 3 are performed, the remaining resources are sequentially allocated to each logical channel in a descending logical channel priority order from high to low regardless of the size of Bj. Only in the case that data on a logical channel of a high priority is all transmitted and the uplink grant is not exhausted, the logical channel with lower priority can be served. That is, in this case, the terminal maximizes data transmission for the logical channel of a high priority.
In summary, in the method according to the embodiments of the present disclosure, by enhancing the LCP procedure, differentiated processing between different PDUs or PDU sets mapped to the same LCH or QoS flow is ensured. It should be understood that, the method according to the embodiments of the present disclosure may be implemented in combination with the foregoing embodiments. The details are not described herein any further.
In some embodiments, taking a PDU set as an example, the method according to the embodiments of the present disclosure may be implemented as follows.

For the related description of the fourth condition, reference may be made to the foregoing content. The details are not described herein any further.
In some embodiments, the status report carries data packet transmission information of an associated PDU set; or the status report carries an SN and/or a status of a data packet.

In some other embodiments, process 702 is further implemented as at least one of:
The second data packet is at least one of the following cases. The second data packet is a data packet in an associated PDU set; the second data packet is a PDU, in the PDU set, not transmitted, not needed, and/or not successfully transmitted; or the second data packet is a PDU set not successfully transmitted; or the second packet is a PDU set that exceeds a PSDB requirement and is not transmitted; or the second data packet is a PDU set that exceeds a PSDB requirement and is not successfully transmitted; or the second data packet is a PDU set that exceeds a packet discarding duration of the PDU set and is not transmitted; or the second data packet is a PDU set that exceeds a packet discarding duration of the PDU set and is not successfully transmitted.
In summary, the method for processing a data packet provided in the embodiments of the present disclosure is a new method for processing a data packet.
In some embodiments, the method may be implemented as follows.
The receiver or the transmitter performs the data packet processing. For example, the UE or a base station performs the data packet processing.
For example, the base station and/or the UE determines whether to perform the data packet processing, and/or how to perform the data packet processing; and for example, the base station and/or the UE determines whether to perform the packet discarding processing and/or how to perform the packet discarding processing.

For example, in the status report, an indication corresponding to an SN of the PDCP PDU/SDU of the associated PDU set is an ACK, or in the status report, it is indicated that a data packet in the PDU set/associated PDU set is lost, no longer needed, or received.
For example, the transmitter or the receiver triggers the status report in the case that the fourth condition is satisfied, and the status report includes an SN of a data packet and/or a status of the data packet (the status includes packet discarded, not needed, considered as received, lost, or the like).

In some embodiments, the resource selection is transmission resource selection, or is HARQ process or resource selection.
In process 802, a transmission resource or a hybrid automatic repeat request (HARQ) process is selected based on at least one of a second PDU, an LCH corresponding to the second PDU, data corresponding to the second PDU, or a logical channel priority.
In some embodiments, the method for selecting a resource according to the embodiments of the present disclosure further includes: prioritizing the logical channel priority; or prioritizing the second PDU; or prioritizing the LCH corresponding to the second PDU; or prioritizing the data corresponding to the second PDU.
In some embodiments, the method for selecting a resource according to the embodiments of the present disclosure further includes at least one of:
In the embodiments of the present disclosure, the second PDU is a specified PDU or a specified data packet. In some embodiments, the specified PDU is a data packet with a third identifier, or the specified PDU is a first data packet. The third identifier is one of an importance identifier, a priority identifier, or a latency value.
In some embodiments, the first data packet is one of: a data packet of importance higher than a threshold; a data packet of a priority higher than a threshold; a data packet with a latency requirement higher than a threshold; a data packet with a PSDB less than a threshold; a data packet with a latency less than a threshold; a data packet with a remaining latency less than a threshold; a data packet with the latency higher than a first threshold and lower than a second threshold; a data packet that does not satisfy a PSDB requirement; a data packet that does not satisfy the PSDB requirement after a first time; or a data packet that does not satisfy the PSDB requirement within the first duration.
For example, the first data packet is a specific data packet. The specific data packet is one of data packets of importance or prioritization, data packets with a high latency requirement, with a small PSDB, with a latency or a remaining latency less than a threshold, with a small latency or a remaining latency (less than others, other LCHs, or other LCHs of the same priority), with a small PSDB or a PSDB less than a threshold, with a latency greater than a threshold 1 and less than a threshold 2, or data packets that do not satisfy or are about to fail satisfying the PSDB requirement.
In the embodiments of the present disclosure, at least one of a PSDB, a latency, a remaining PSDB, or a remaining latency is determined by MAC or a PDCP through statistics. The MAC or the PDCP determines at least one of the PSDB, the latency, the remaining PSDB, or the remaining latency based on a first duration or a first timer.
In some embodiments, the first duration or the first timer is started in the case that a data packet or a data packet of a PDU set arrives, is stored, or is available. For example, the first duration or the first timer is started in the case that the data packet or the data packet of the PDU set (for example, the first data packet, where for example, whether the PDU set or not is determined based on an SN of the PDU set) arrives, is stored, or is available.
In some embodiments, the latency/remaining latency/PSDB/remaining PSDB/duration is determined in the resource selection process.
In some embodiments, the PSDB, the latency, the remaining PSDB, the remaining latency, and the duration are determined in the MAC or the PDCP. For example, the PSDB, the latency, the remaining PSDB, the remaining latency, and the duration are interacted to the MAC by another layer (for example, the PDCP layer).
In some embodiments, whether a data packet belongs to the PDU set is determined by the MAC based on a higher layer packet header, or is determined based on inter-layer interaction, or is determined based on a control PDU.
For descriptions related to the latency in the embodiments of the present disclosure, reference may be made to the foregoing content. The details are not described herein any further.
In summary, a new method for selecting a resource is provided in the embodiments of the present disclosure.
In some embodiments, the resource selection method is implemented as follows.
In the case of resource conflict, or in the case of selection of a resource for preferential transmission, or in a HARQ selection process, a specific PDU or an LCH/data of a specific PDU is used as one of the factors for the selection; or the selection is performed based on an LCH priority and/or a specific PDU or an LCH/data of a specific PDU.
In some embodiments, in the resource selection process, the LCH priority is prioritized, or the specific PDU or the LCH/data of the specific PDU is prioritized. For example, a HARQ or a grant for an LCH of a high priority is preferentially transmitted, or a HARQ or a grant including the specific PDU or the LCH/data of the specific PDU is preferentially transmitted.
In some embodiments, in the resource selection process, the LCH priority is prioritized, and the specific PDU or the LCH/data of the specific PDU is then considered. For example, in HARQ/grant selection for LCHs of the same priority, the specific PDU or the LCH/data of the specific PDU is prioritized.
In some embodiments, in the resource selection process, the specific PDU or the LCH/data of the specific PDU is prioritized, and the LCH priority is then considered. For example, in the case that all HARQs/grants include the specific PDU or the LCH/data of the specific PDU, one of a higher LCH priority is selected.
In some embodiments, in the resource selection process, an LCH corresponding to the specific PDU is prioritized, or a HARQ/resource for data of an LCH corresponding to a specific PDU set is preferentially transmitted, or the specific PDU is prioritized, or a HARQ/resource for data of a specific PDU is preferentially transmitted, or an LCH priority during the current selection is adjusted, or a priority of an LCH/LCH corresponding to the specific PDU is adjusted to a high or highest priority.
In some embodiments, the specific PDU is a PDU, a PDU set, or a data packet.
For example, the specific PDU is a PDU of importance, priority, low-latency, low-PSDB, or the like. Alternatively, the specific PDU is a packet with a specific identifier. The specific identifier includes any one of importance, a priority, a latency value, a PSDB identifier, or the like. Alternatively, the specific PDU is a PDU with a latency, a remaining latency, a remaining PDB, or a remaining PSDB less than a threshold; or the specific PDU is a PDU with a small latency, remaining latency, remaining PDB, or remaining PSDB (less than others, other LCHs, or other LCHs of the same priority); or the specific PDU is one of a PDU with a small PSDB or a PSDB less than a threshold, a PDU with a latency greater than a threshold 1 and less than a threshold 2, a PDU that does not satisfy or is about to fail satisfying a PDB/PSDB requirement, or an associated PDU.
In some embodiments, in a prioritization procedure or HARQ process selection, the UE takes latency information (for example, a remaining duration for waiting) of a PDU set/LCH/LCG/LCH pair into account;
The indication/enabler/parameter may be from the network side (for example, the gNB or a core network), or the indication/enabler/parameter may be from the application layer or an application server, or the indication/enabler/parameter may be pre-configured to the UE.
In some embodiments, solution 1, solution 2, and solution 3 are implemented separately, or are implemented in any combination.
In some embodiments, at least one of solution 1, solution 2, or solution 3 is implemented in any combination with at least one of solution 4 to solution 7.
In some embodiments, for one or more types of information related to solution 1, solution 2, and solution 3, in the case that a network device allocates a transmission resource or allocates a UL transmission resource based on a report, the UL transmission resource carries an indication, wherein the indication indicates a resource type. In some embodiments, the resource type indicates data or an LCH that can be multiplexed onto the UL transmission resource. For the UE, only data or an LCH of a corresponding resource type can be multiplexed onto the UL transmission resource.
In some embodiments, for one or more types of information related to solution 1, solution 2, and solution 3, in the case that a network device allocates a transmission resource or allocates a UL transmission resource based on a report, the UL transmission resource carries an indication, wherein the indication indicates a resource type or a resource indication. In some embodiments, the resource type or the resource indication indicates data or an LCH that can be multiplexed onto the UL transmission resource, or indicates use of a first LCP (LCP enhancement in solution 5) or a first HARQ selection or prioritization procedure (the HARQ selection or priority selection enhancement in solution 7). For the UE, only data or an LCH of a corresponding resource type can be multiplexed onto the UL transmission resource, or the UE performs packaging or resource transmission using a solution corresponding to the resource indication (for example, the LCP, the HARQ selection, or the priority selection).
In some embodiments, in the case that a network device allocates a transmission resource or allocates a UL transmission resource, the UL transmission resource carries an indication, wherein the indication indicates a resource type.

For the UE, only data or an LCH of a corresponding resource type can be multiplexed onto the UL transmission resource.
In some embodiments, in the case that a network device allocates a transmission resource or allocates a UL transmission resource, the UL transmission resource carries an indication, wherein the indication indicates a resource type or a resource indication.

For the UE, only data or an LCH of a corresponding resource type can be multiplexed onto the UL transmission resource, or the UE performs packaging or resource transmission using a solution corresponding to the resource indication (for example, the LCP, the HARQ selection, or the priority selection).
In some other embodiments, the packaging, the resource selection, or the resource transmission is performed based on specific information.
In some embodiments, specific indication information is configured for an LCH, RLC, or a DRB, to indicate a resource type corresponding to the LCH, the RLC, or the DRB. In some embodiments, in the case that the resource type matches (for example, is the same as) a resource type configured or scheduled by the network, the LCH, the RLC, or the DRB is transmitted using a resource configured or scheduled by the network, or is borne/multiplexed on a resource configured or scheduled by the network. In some embodiments, specific information is configured for an LCH, RLC, or a DRB, to indicate a data type corresponding to the LCH, the RLC, or the DRB. In some embodiments, the data type corresponds to information of a PDU set or a data burst, or is information (for example, attributes) of a PDU set or a data burst; or the data type is an identifier supported by a PDU set or a data burst. Alternatively, the data type may be a specific identifier.
In some embodiments, the specific indication information or the specific information is pre-configured, determined by the UE, or configured by RRC.
