Patent Application
20230397290
This application relates to the field of communication processing technology, and particularly to a method for uplink data transmission, a user equipment (UE), and a storage medium.
If a user equipment (UE) in an inactive state has data to be uploaded, the data can be transmitted after a radio resource control (RRC) connection is resumed, or transmission in the inactive state can be achieved by introducing small data transmission (SDT). If the UE needs to perform data transmission multiple times in the inactive state, a service beam of the UE may change. Considering that the UE in the inactive state may not frequently measure the beam and report a measurement result, a network may not provide data transmission for the UE through the original beam, resulting in failure of the data transmission multiple times and further affecting spectrum efficiency and a network performance.
In a first aspect, a method for uplink data transmission is provided. The method is performed by a user equipment (UE). The method includes: indicating in small data transmission (SDT) associated information of data to-be-transmitted, when the UE is in an inactive state and has the data to-be-transmitted.
In a second aspect, a UE is provided. The UE includes a processor and a memory. The memory is coupled with the processor and stores programs. The programs include instructions which are operable with the processor to execute the operations of the method in the first aspect.
In a third aspect, a non-transitory computer-readable storage medium is provided. The non-transitory computer-readable storage medium stores computer programs which, when executed by a UE, cause the UE to execute the method in the first aspect.
The following will give a description of accompanying drawings used for describing implementations of disclosure.
Hereinafter, implementations of the disclosure are depicted with reference to accompanying drawings used for the implementations of the disclosure.
The term “and/or” of the disclosure is merely used to describe an association relationship of associated objects, and indicates that there can be three relationships. For example, “A and/or B” means that: A alone, both A and B, or B alone. In addition, the character “I” herein generally indicates that associated objects before and after the character are in an “or” relationship.
The term “a plurality of/multiple” appearing in implementations of the disclosure means two or more. The descriptions of the “first”, “second”, and the like appearing in implementations of the disclosure are merely used for illustration and distinguishing described objects, and do not indicate an order, nor do they indicate a special limitation on the number of devices of implementations of the disclosure, which should not constitute any limitation to implementations of the disclosure. The “connection” appearing in implementations of the disclosure refers to various connection modes such as direct connection or indirect connection, to realize communication between devices, which is not limited in implementations of the disclosure.
Technical solutions of implementations of the disclosure can be applied to an exemplary communication system 100 illustrated in
In new radio (NR), when the UE has a service demand, the UE will access a network to establish a radio resource control (RRC) connection, to establish a dedicated bearer for data transmission. After the UE enters a connected state, a base station will allocate necessary parameters for the UE such as a security algorithm, L2-related configuration parameters, physical layer-related configuration parameters, and layer 3-related configuration parameters (e.g., wireless link failure parameter and other parameters). For the established bearer, the base station needs to know information about a channel which is established for the bearer and between a core network and the bearer. These parameters are referred to as UE context. When the UE enters an idle state from the connected state, the base station will release all parameters of the UE, that is, releasing the UE context. If the UE wants to establish a service again, the base station needs to reconfigure the above parameters for the UE. This process will be completed through multiple air interface signaling and NG interfaces (an interface between the base station and the core network) signaling.
In practice, different UEs may have different service demands. For example, some UEs may transmit data multiple times within a time period, and the time for each data transmission is limited. For this type of service demand, if the existing mechanism is adopted, a connection needs to be established for each data transmission, and the connection will be released once the data transmission is completed. Repeated multiple transmissions by the UE will cause a large number of signaling interactions, which in turn leads to an excessive network signaling load and a large decrease in efficiency of data transmission.
In NR, the inactive state is introduced, in which the UE does not perform data transmission with the network but can receive paging periodically. The network retains configuration of an RRC connection established by the UE, bearer configuration, security configuration, and parameter configuration of an NG interface related to the UE. The UE also needs to save the configuration of the RRC connection, the bearer configuration, the security configuration, and so on. When the UE in the inactive state has data to be transmitted, the UE can use the saved parameter configuration to quickly access the network and resume the RRC connection through an RRC resume procedure, and then perform data transmission. Since both the UE and the network have the RRC connection parameters of the UE, the UE can quickly access the network to transmit data. Since the UE does not have to establish an RRC connection and a bearer for data transmission, a lot of signaling can be saved.
For a smart terminal, the UE in the inactive state may still have a small data transmission (SDT) demand. If the UE resumes the RRC connection for data transmission every time, transmission efficiency will still be low.
Referring to
At 201, a terminal device transmits a random access preamble to a network device, where the random access preamble is message 1 (Msg1) in the four-step random access procedure.
At 202, the network device transmits a random access response (RAR) message to the terminal device, where the RAR message is message 2 (Msg2) in the four-step random access procedure.
At 203, the terminal device transmits a scheduled transmission message to the network device, where the scheduled transmission message is message 3 (Msg3) in the four-step random access procedure.
At 204, the network device transmits a contention resolution message to the terminal device, where the contention resolution message is message 4 (Msg4) in the four-step random access procedure.
In order to realize the SDT, the base station will allocate relatively large uplink transmission resources for the UE in random access response, so that the UE can transmit small data in Msg3 (i.e., message 3), and at the same time transmit an RRC message such as containing identity information of the UE, etc.
A two-step random access procedure is also introduced in NR. Another SDT method can be realized through two-step random access. Referring to
The UE camps on an NR serving cell and is in an inactive state.
The UE generates some data that needs to be transmitted to a network side. Considering that the amount of the data is small, the UE decides to use an SDT method.
Moreover, the UE finds that transmission of the data amount cannot be completed at one time. For a two-step random access method, the UE can know an amount of data that can be uploaded on a physical uplink shared channel (PUSCH) of the MsgA from configuration of two-step random access in a system message of a cell, and the UE can calculate, according to a size of physical resources occupied by the PUSCH and a modulation-coding scheme adopted, an amount of data that can be uploaded, which does not include a number of bits (that is, quantity, how many) occupied by RRC signaling that needs to be transmitted in the MsgA. For the four-step random access procedure, a resource size of Msg3 is allocated by the base station dynamically, and the UE cannot directly determine whether the entire transmission can be completed at one time without receiving a random access response. Generally, the base station will not allocate very large transmission resources to avoid resource waste. In this situation, the UE may assume that the base station allocates a fixed number of physical resource blocks (e.g., 4 PRBs) at one time, and determine whether transmission of data to-be-transmitted can be completed at one time according to an amount of data that can be transmitted on the 4 PRBs. Alternately, the UE may also monitor RAR messages of other UEs, know from these RAR messages a size of physical resources allocated by the base station at one time, so as to know an amount of data that can be transmitted at one time. Alternatively, when receiving a random access response transmitted by the base station, the UE may determine the amount of data that can be transmitted at one time according to allocated PUSCH resources. Alternatively, the base station may indicate through a system message an amount of data that is predicted to be transmitted at one time, so that the UE can accurately determine whether transmission of data to-be-transmitted can be completed at one time. The UE may continuously generate uplink data, in this situation, the UE may determine that transmission of data to-be-transmitted cannot be completed at one time.
Referring to
At S300, if a UE is in an inactive state and has data to-be-transmitted, the UE indicates in SDT associated information of the data to-be-transmitted.
According to the technical solution of the disclosure, when the UE is in the inactive state and has the data to-be-transmitted, the UE can indicate in the SDT the associated information of the data to-be-transmitted, and report the associated information to the base station, so that the base station can configure resources for the UE according to the associated information, thereby improving a network performance. The data to-be-transmitted may be data that is currently generated by a UE side and needs to be uploaded (which generally refers to data that is already in a buffer of layer 2, that is, available data), or may include data that will be generated by the UE and needs to be uploaded.
In an alternative implementation, the associated information of the data to-be-transmitted includes one or any combination of the following: an interval of resource allocation, an amount of data that can be transmitted in each resource allocation, a duration of data transmission, and a number of times (that is, quantity, how many) of subsequent resource allocation.
The duration of data transmission herein may be a total duration of the transmission, or may include a duration of each transmission, because the UE may generate data periodically, for example, uplink data needs to be transmitted every 40 ms, and each transmission needs to last for 6 ms. The duration of data transmission may refer to the duration of each transmission or the total duration of the data transmission. If the UE expects to transmit data of 100 periods and the period is 40 ms, the total duration of the transmission is 100×40=4000 ms.
In an alternative implementation, the method further includes: determining, by the UE, a service characteristic of the data to-be-transmitted, and indicating, by the UE, in the SDT the associated information of the data to-be-transmitted when the service characteristic is different from a service characteristic reported before the UE enters the inactive state. The UE may only indicate indicators of different service characteristics, and does not need to indicate complete service characteristics.
Before entering the inactive state, the UE generally indicates to the base station service characteristics of logical channels or different data radio bearers, such as an interval of service generation, a size of data generated each time, and other parameters. A network switches the UE into the inactive state when there is no data transmission on the data radio bearer or the logical channel. After a certain time period, new data is generated again on the data radio bearer or the logical channel of the UE, so the UE transmits the new data through the SDT method. However, a service characteristic corresponding to the newly generated data (e.g., an interval of data generation, a size of data generated each time) may be the same as or different from a service characteristic reported by the UE before. In order to save signaling, the interval of data generation and the size of data generated each time can be indicated when the service characteristic corresponding to the newly generated data is different from the service characteristic reported by the UE before. The duration of data transmission (or the number of times of subsequent resource allocation) also needs to be indicated.
In an alternative implementation, the service characteristic includes one or any combination of the following: a size of service data generated each time, an interval period of service generation, and a time deviation of service data generation.
The time deviation refers to a start time point at which data is generated in a period. As an example, the interval period of service generation is 40 ms, and data is generated at the sixth ms in the period of 40 ms.
In an alternative implementation, the method further includes: reporting, by the UE, an amount of the data to-be-transmitted through a buffer status report (BSR) or preset signaling, where the amount of the data to-be-transmitted contains an amount of existing data to-be-transmitted and an amount of data that is predicted to be transmitted.
In an alternative implementation, the method further includes: skipping, by the UE, indicating that there is subsequent data transmission when the UE determines that a generation interval of the data to-be-transmitted exceeds an interval threshold, and transmitting, by the UE, data generated next through a next SDT process upon next data generation.
The above interval threshold may be configured by the base station through a system message, or may be a threshold set by a protocol.
In an alternative implementation, the associated information of the data to-be-transmitted includes a channel quality of a beam currently accessed by the UE.
In an alternative implementation, the associated information of the data to-be-transmitted further includes a channel quality and a beam identifier of at least one candidate beam.
In an alternative implementation, indicating, by the UE, in the SDT the associated information of the data to-be-transmitted specifically includes: indicating, by the UE, the associated information of the data to-be-transmitted through message 3 (Msg3) or message a (MsgA) of the SDT.
In an alternative implementation, when transmission of the data to-be-transmitted cannot be completed in one SDT, the UE indicates in the SDT the associated information of the data to-be-transmitted.
The First Implementation
The first implementation of the disclosure provides a method for uplink data transmission. An implementation scenario of the implementation of the disclosure may be the communication system illustrated in
At S400, the UE finds that transmission of the data to-be-transmitted cannot be completed at one time through an SDT method, and the UE indicates in MsgA/Msg3 an interval of subsequent resource allocation, an amount of data that can be transmitted in each resource allocation, a duration of data transmission, or a number of times of subsequent resource allocation.
Optionally, the MsgA/Msg3 may contain an RRC message, and the interval of subsequent resource allocation, the amount of data that can be transmitted in each resource allocation, or the duration of data transmission (the duration of data generation), or the number of times of subsequent resource allocation are indicated in the RRC message, so that a base station can reasonably allocate subsequent uplink transmission resources.
At S401, the base station allocates periodic uplink transmission resources for the UE according to an amount of data each time and the interval indicated by the UE, and the base station releases the allocated periodic resources once data transmission reaches the duration indicated by the UE.
When the UE determines that the data to-be-transmitted cannot be transmitted through one SDT, that is, subsequent data transmission is required, the interval of subsequent resource allocation and a size of a resource allocated each time can be indicated in MsgA/Msg3, where MsgA/Msg3 may contain an RRC message, and the interval of subsequent resource allocation, the amount of data that can be transmitted in each resource allocation, or the duration of data transmission (the duration of data generation) are indicated in the RRC message, so that the base station can reasonably allocate subsequent uplink transmission resources, and accordingly, the UE can transmit uplink data in time to avoid resource waste. As an example, the base station can allocate periodic uplink transmission resources for the UE according to the amount of data each time and the interval indicated by the UE, and the base station can release the allocated periodic resources after the data transmission reaches the duration indicated by the UE. As such, timely and efficient data transmission can be realized with the least signaling interaction.
The Second Implementation
The second implementation of the disclosure provides a method for uplink data transmission. An implementation scenario of the implementation of the disclosure may be the communication system illustrated in
At S500, an access layer of a UE can interact with applications to obtain service characteristics of different applications and predict subsequent data transmission, and turn to subsequent operations if the subsequent data transmission is multiple data transmissions.
The interaction between the access layer of the UE and the application belongs to internal implementation of the UE, and may be implemented in various ways, for example, the UE can count service characteristics of different applications (e.g., WeChat® and Weibo®) by itself, which is not limited in the disclosure.
At S501, the UE obtains a generation interval of data to-be-transmitted, and the UE will not indicate that there is subsequent data transmission once the generation interval exceeds an interval threshold (indicate that there is subsequent data transmission only when the generation interval is shorter than the interval threshold). When the interval threshold is exceeded, the UE transmits through SDT when data generated next needs to be transmitted.
According to the technical solution of the disclosure, if a duration for the UE to generate data next time exceeds the interval threshold, the UE skips indicating the need for subsequent transmission resources (that is, indicate that there is subsequent transmission when the duration is shorter than the interval threshold). The UE will re-initiate an SDT process once there is data transmission next time. As such, it is avoided that a current beam cannot support data transmission due to UE movement in case of excessively long interval, which can improve reliability of data transmission and a network performance
The Third Implementation
The third implementation of the disclosure provides a method for uplink data transmission. An implementation scenario of the implementation of the disclosure may be the communication system illustrated in
At S600, a UE indicates in Msg3/MsgA a channel quality or an identifier of a currently accessed beam.
At S601, a base station selects an appropriate modulation-coding scheme according to indication in Msg3/MsgA.
According to the technical solution of the disclosure, the UE can indicate in MsgA or Msg3 the channel quality of the currently accessed beam. Optionally, the UE can indicate a channel quality of a (candidate) good beam, such as a channel quality of a beam exceeding a signal-quality threshold. Since the UE needs to transmit data multiple times, a beam accessed by the UE may change during the multiple data transmission (the UE determines a corresponding preamble according to a selected beam in a random access procedure, and the base station determines the beam accessed by the UE according to the preamble transmitted by the UE). In order to improve transmission efficiency, the UE reports a signal quality of the accessed beam, such as a channel quality index (CQI), which helps the base station to select an appropriate modulation-coding scheme to improve transmission efficiency and spectrum efficiency. The UE can report the channel quality of the currently accessed beam, and can also report a signal quality of a candidate beam(s). If the currently accessed beam is the strongest beam in a serving cell measured by the UE and the UE also detects one or more second-strongest beams, the UE can report a beam identifier and a channel quality of the second-strongest beam or only report the beam ID, so that the base station can know a candidate beam(s) of the UE, select a candidate beam to provide services for the UE, and know a channel quality of the candidate beam measured by the UE. As such, when a beam serving the UE changes, an appropriate modulation-coding scheme can be selected for data transmission.

In combination with algorithm steps/operations of each example described in the implementations disclosed herein, the disclosure can be implemented in hardware or a combination of hardware and computer software.
