Description

Information processing method and device, chip, device and storage medium

Technical Field

The present application relates to communication technology, and relates to, but is not limited to, information processing methods and apparatuses, chips, devices, and storage media.

Background

Packet transmission (Small Data Transmission, SDT) is a mechanism introduced by the third generation partnership project (3rd Generation Partnership Project,3GPP) in version R17 to support the User Equipment (UE) in an inactive state to transmit uplink packet data, and is applicable to packet data services such as health monitoring data upload and application push. Based on this, the transmission modes of the packet data include packet transmission (CG-SDT) based on network pre-Configured resources and packet transmission (RA-SDT) based on contention resolution. The CG-SDT, as the name implies, refers to that the network device configures related resources for UE to perform uplink packet transmission in advance, so that the UE can transmit packet data based on the related resources; RA-SDT refers to a UE randomly accessing a target cell based on a contention manner to establish a connection with the target cell, thereby transmitting packet data based on the connection established with the target cell.

However, when the UE transmits the uplink packet data, there are problems of resource waste and increased power overhead on the UE side.

Fig. 1 illustrates one network architecture to which embodiments of the present application may be applicable. As shown in fig. 1, a network architecture provided in an embodiment of the present application includes: a user device 101 and a network device 102. The user equipment 101 according to the embodiment of the present application may include various handheld devices, vehicle-mounted devices, wearable devices, computing devices or other processing devices connected to a wireless modem, and various types of user terminal devices or Mobile Stations (MSs) and the like. The network device 102 according to the embodiment of the present application is a device deployed in a radio access network to provide a wireless communication function for the user device 101; for example, network device 102 may include various forms of macro base stations, micro base stations, relay stations, or access points, among others.

The information processing method provided by the embodiment of the application can be applied to the user equipment 101. In this embodiment of the present application, the user equipment 101 may also be described as a terminal side device, a terminal, a mobile terminal, a UE, or a user equipment, and the name of the user equipment 101 is not limited in this embodiment of the present application.

The information processing method provided by the embodiment of the application can be applied to various communication systems, wherein the communication systems can be a fourth generation mobile communication system (the 4th generation mobile communication system,4G), a fifth generation mobile communication technology (5 th-Generation wireless communication technology, 5G) New air interface (NR) system or future communication systems, and can also be other various wireless communication systems.

The communication system described in the above embodiments and the network architecture shown in fig. 1 are for more clearly explaining the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided by the embodiments of the present application. As one of ordinary skill in the art can appreciate, with the evolution of the communication system and the network architecture, the technical solutions provided in the embodiments of the present application are applicable to similar technical problems.

As shown in fig. 1, SDT is introduced to support transmission of packet data by a user equipment 101 to a network device 102 in a target cell where the user equipment resides in an inactive state, and is applicable to packet data services such as uploading of health monitoring data and pushing. Types of SDT include CG-SDT and RA-SDT; wherein CG-SDT, as the name implies, refers to that network device 102 configures related resources for uplink packet transmission for user device 101 in advance, so that user device 101 may transmit packet data based on the related resources; RA-SDT, then means that the user equipment 101 randomly accesses the target cell based on a contention manner to establish a connection with the network device 102 in the target cell, thereby transmitting packet data based on the connection.

An embodiment of the present application provides an information processing method, and fig. 2 is a schematic implementation flow diagram of the information processing method provided in the embodiment of the present application, as shown in fig. 2, where the information processing method includes the following steps 201 to 210:

step 201, the radio resource management (Radio Resource Control, RRC) layer of the user equipment 101 receives the upper layer data and informs the radio link control (Medium Access Control, MAC) layer of the user equipment 101 of the transmission;

step 202, the mac layer determines whether the size of the data packet is greater than a second threshold; if yes, go to step 210; otherwise, step 203 is performed.

In some embodiments, the second threshold is a threshold configured by the network device 102 to support data packets transmitted by the user device 101 using an SDT mechanism. If the size of the data packet transmitted by the ue 101 is less than or equal to the second threshold, the network device 102 supports the ue 101 to transmit the data packet in the SDT mechanism.

In the embodiment of the present application, the data packet smaller than or equal to the second threshold may be referred to as packet data or a small data packet.

Step 203, the mac layer determines whether to configure the SDT RSRP threshold; if yes, go to step 204; otherwise, go to step 205; wherein the SDT RSRP threshold value refers to an average threshold value of RSRP of the configured synchronization signal block (Synchronization Signal Block, SSB);

Step 204, the mac layer determines whether the current RSRP is greater than or equal to the SDT RSRP threshold; if yes, go to step 205; otherwise, go to step 210; wherein, the current RSRP refers to the average value of the RSRP of the configured SSB;

step 205, the MAC layer judges whether to configure CG-SDT resource; if yes, go to step 206; otherwise, go to step 207;

step 206, the MAC layer judges whether SSB-RSRP is greater than or equal to CG-SDT RSRP threshold; if yes, go to step 209; otherwise, go to step 207; wherein, SSB-RSRP refers to the RSRP of one SSB; the CG-SDT RSRP threshold value refers to the RSRP threshold value of any configured SSB; in the case where the RSRP of at least one of the configured SSBs satisfies the same CG-SDT RSRP threshold value, the SSB-RSRP may be considered to be greater than or equal to the CG-SDT RSRP threshold value.

Step 207, the mac layer performs RA;

step 208, the mac layer determines whether RA is successful; if yes, go to step 209; otherwise, go to step 210;

in step 209, the mac layer informs the RRC layer of SDT data transmission.

In step 210, the mac layer informs the RRC layer of the non-SDT transmission.

It may be understood that, in the information processing method provided in the foregoing embodiment, when the current RSRP is greater than or equal to the SDT RSRP threshold and the packet data transmission mode is configured to be CG-SDT and SSB-RSRP is less than the CG-SDT RSRP threshold, the user equipment 101 randomly accesses the target cell (i.e., the cell currently residing), transmits the packet data by using the RA-SDT mechanism, and if the random access fails, the packet data needs to be transmitted by using a non-SDT mode. It can be seen that, on the one hand, although the network device 102 in the target cell configures the relevant resources for the user equipment 101 to perform the packet data transmission in advance, the preconfigured relevant resources may not be used in performing the packet data transmission, and the RA-SDT mechanism or the non-SDT mechanism is used for performing the packet transmission, thereby causing resource waste and increasing power consumption.

In view of this, the embodiment of the present application provides an information processing method, which may be applied to the user equipment 101 of fig. 1, and fig. 3A is a schematic implementation flow chart of the information processing method provided in the embodiment of the present application, as shown in fig. 3A, and the information processing method includes the following steps 301a:

step 301a, the user equipment 101 adjusting down at least one SDT RSRP threshold value based on determining that transmission using the RA-SDT mechanism has failed at least once; the at least one SDT RSRP threshold is used to determine whether to employ a CG-SDT mechanism for transmission.

In the embodiment of the present application, the user equipment 101, based on determining that transmission using the RA-SDT mechanism fails at least once, lowers at least one SDT RSRP threshold value used for determining whether transmission using the CG-SDT mechanism is performed; in this way, on the one hand, in the subsequent transmission process, the chance/probability of adopting the CG-SDT mechanism to transmit can be increased, so as to reduce the probability of adopting the RA-SDT mechanism to transmit by the user equipment 101, and further reduce the failure times of RA-SDT, that is, reduce the times of adopting the non-SDT mechanism to transmit. The power consumption caused by non-SDT is higher than that caused by CG-SDT, so in the embodiment of the present application, the user equipment 101 actively lowers the RSRP threshold of SDT, and the opportunity that the user equipment 101 adopts a non-SDT mechanism to transmit is reduced, thereby being beneficial to saving the power consumption.

On the other hand, it can be appreciated that in the CG-SDT mechanism, the network device 102 configures related resources (such as time-frequency resources and CG-SDT RSRP threshold values, etc.) for the user device 101 in advance for packet data transmission, and if the user device 101 does not use the time-frequency resources configured by the network device 102 during transmission, the time-frequency resources are occupied and are not released for other user devices to use, which is obviously a resource waste. Therefore, in the embodiment of the application, the SDT RSRP threshold value is reduced, so that the opportunity/probability of adopting the CG-SDT mechanism for transmission can be increased, and the resource utilization rate is improved.

Further alternative embodiments of the above steps, and related terms, etc., are described below, respectively.

In step 301a, the user equipment 101, based on a determination that transmission using the RA-SDT mechanism failed at least once, lowers at least one SDT RSRP threshold; the at least one SDT RSRP threshold is used to determine whether to employ a CG-SDT mechanism for transmission.

In the embodiment of the present application, the user equipment 101 fails to transmit the data packet less than or equal to the second threshold value at least once based on the determination that the RA-SDT mechanism is adopted; the at least one failure may be that the number of failures of the user equipment 101 to transmit to the target cell by using the RA-SDT mechanism is 1 or more; further, the at least one failure may be that the number of failures of the user equipment 101 to transmit to the target cell using the RA-SDT mechanism within a certain period of time is 1 or more; the target cell refers to a cell where the user equipment 101 currently resides.

In other words, in some embodiments, the user equipment 101 adjusts down at least one SDT RSRP threshold based on determining that the transmission to the target cell failed at least once using the RA-SDT mechanism.

In this embodiment of the present application, the timing for lowering the at least one SDT RSRP threshold is not limited, and the threshold may be lowered by adopting the RA-SDT mechanism to fail transmission once, or by adopting the RA-SDT mechanism to fail transmission multiple times. In some embodiments, the at least one SDT RSRP threshold value is lowered based on determining that the number of failures to transmit using the RA-SDT mechanism is greater than or equal to a first threshold value.

In the embodiment of the present application, the determination manner of the first threshold is not limited; in some embodiments, the first threshold may be set according to a communication latency that the user equipment 101 can tolerate when the target cell is in a network congestion state; the first threshold may be set, for example, according to a maximum communication latency that the user equipment 101 can tolerate when the target cell is in a network congestion state.

It will be appreciated that the ue 101 may transmit multiple data packets, where there may be the same data packet (e.g., retransmitted data packet) or may be different from one data packet to another; thus, for a number of failures transmitted using the RA-SDT mechanism that is greater than or equal to the number of failures in the first threshold, it may include a number of failures transmitted using the RA-SDT mechanism for the same data packet and a number of failures transmitted using the RA-SDT mechanism for a different data packet.

In this embodiment, the user equipment 101 decreases the at least one SDT RSRP threshold value based on determining that the number of failures of transmission using the RA-SDT mechanism is greater than or equal to a first threshold value. The subsequent user equipment 101 accumulates the number of failures after each failure of transmission using the RA-SDT mechanism, and when the number of failures is greater than or equal to the first threshold, again lowers the current at least one SDT RSRP threshold.

In the embodiment of the present application, it is not limited whether the accumulation operation of the failure times is related to the first threshold, and in some embodiments, the accumulation operation of the failure times is not related to the first threshold; for example, whether the accumulated failure frequency T is greater than, less than or equal to the first threshold value after the previous transmission failure using the RA-SDT mechanism, 1 should be added again based on the previous failure frequency T after the current transmission failure using the RA-SDT mechanism, which is the accumulated failure frequency of the current time.

For example, after the transmission fails by the RA-SDT mechanism, the user equipment 101 adds up the number of failures to be equal to the first threshold; after the user equipment 101 fails again in the next transmission process by adopting RA-SDT transmission, 1 is added again on the basis of the current failure number, so as to obtain the latest failure number, and the latest failure number is necessarily larger than the first threshold value.

It can be appreciated that, in this embodiment, if the number of accumulated times is greater than the first threshold after the RA-SDT transmission fails, the number of accumulated times is greater than the first threshold after each subsequent RA-SDT transmission failure, so that at least one SDT RSRP threshold needs to be adjusted after each subsequent RA-SDT transmission failure; in this way, in the subsequent transmission process, the opportunity/probability of adopting the CG-SDT mechanism for transmission can be further increased, thereby saving the electric quantity overhead and improving the resource utilization rate.

In other embodiments, the accumulation of the number of failures is associated with a first threshold; illustratively, the number of failures is cleared based on determining that the number of failures transmitted using the RA-SDT mechanism is greater than or equal to a first threshold. That is, every time the number of failures is increased to the first threshold or the number of failures is greater than the first threshold, the number of failures is counted again after 0 is cleared.

For example, after the transmission fails by using the RA-SDT mechanism, the user equipment 101 counts up the number of failures equal to the first threshold, and clears the number of failures counted up this time to 0; and after the next transmission failure by adopting the RA-SDT mechanism, adding 1 on the basis of 0 to obtain the accumulated failure frequency of 1.

In this embodiment, after the accumulated number of failures is greater than or equal to the first threshold, the number of failures is accumulated again after clearing 0, instead of being accumulated again on the basis of the first threshold. It can be understood that the channel fluctuation can cause frequent failure of transmission by adopting an RA-SDT mechanism, if the failure times are continuously accumulated for 0, the threshold value can be frequently lowered due to the channel fluctuation, so that the data packet which originally does not meet the CG-SDT transmission condition is also transmitted by adopting the CG-SDT mechanism, and the data transmission quality can not be ensured; therefore, after the accumulated failure times are greater than or equal to the first threshold value, the failure times are accumulated after the failure times are cleared to 0, so that frequent threshold value lowering caused by channel fluctuation can be avoided, and the data transmission quality is ensured.

In the embodiment of the present application, the accumulation operation of the failure times and whether the cell handover is related are not limited; in some embodiments, the accumulation of failure times is related to cell handover; illustratively, based on determining that the user equipment 101 has cell handover, the number of failures is cleared; that is, after the user equipment 101 is handed over from the target cell to another cell, the number of failures accumulated in the target cell is cleared to 0.

For example, after the ue 101 switches from the current target cell to another cell, the number of failures accumulated in the target cell is cleared to 0, and after the other cell fails to transmit by RA-SDT for the first time, 1 is added on the basis of 0 to obtain the number of failures accumulated in the current target cell; after the subsequent transmission failure by adopting the RA-SDT mechanism, the failure times are accumulated again on the basis of 1.

It can be understood that the number of failures transmitted by the RA-SDT mechanism can represent the congestion status of the network, the network congestion status of different cells is different, and the number of failures transmitted by the RA-SDT mechanism in the target cell represents the network congestion status of the target cell but cannot represent the network congestion status of another cell; therefore, when the cell switching happens, the failure times are cleared to 0, and whether at least one SDT RSRP threshold value should be regulated down is judged according to the accumulated failure times in the other cell, so that the probability of packet transmission resource transmission based on network side configuration can be increased when the network of the other cell is congested.

In the embodiment of the present application, when the number of failures is greater than or equal to the first threshold, the at least one SDT RSRP threshold is turned down once, but the number of times the at least one SDT RSRP threshold is turned down is not limited in general, and in some embodiments, the at least one SDT RSRP threshold may be turned down once in total, or the at least one SDT RSRP threshold may be turned down multiple times in total.

Illustratively, after the user equipment 101 fails to adopt the RA-SDT mechanism this time, the number of failures accumulated this time is greater than or equal to the first threshold, and thus, the current at least one SDT RSRP threshold is turned down once; after the subsequent ue 101 fails again with RA-SDT transmission, if the number of failures accumulated for this time is greater than or equal to the first threshold, at least one SDT RSRP threshold is turned down once again based on the last turn down.

It can be understood that after at least one SDT RSRP threshold value is lowered once, the subsequent transmission by using the RA-SDT mechanism still fails, which indicates that the at least one SDT RSRP threshold value after the lowering temporarily does not meet the condition of transmission by using the CG-SDT mechanism, so that the at least one SDT RSRP threshold value can be lowered again; in this way, in the subsequent transmission process, the opportunity/probability of adopting the CG-SDT mechanism for transmission can be further increased, thereby saving the electric quantity overhead and improving the resource utilization rate.

In one possible implementation, the at least one SDT RSRP threshold value is not supported to be turned down indefinitely, and before turning down the at least one SDT RSRP threshold value, the method further comprises: determining that the number of times the at least one SDT RSRP threshold is turned down is less than a number of times threshold; and/or determining that the current at least one SDT RSRP threshold is greater than the threshold. That is, the number of times at least one SDT RSRP threshold is lowered is limited, the total number of times of lowering does not exceed the number of times threshold, and the threshold after lowering should be greater than or equal to the threshold value.

It will be appreciated that the initial at least one SDT RSRP threshold is configured by the network device 102, and when the initial at least one SDT RSRP threshold is met, for example, when the average value of RSRP of the configured SSBs is greater than or equal to the initial first RSRP threshold and the RSRP of at least one of the configured SSBs is configured with CG-SDT resources, and the RSRP of the configured SSB is greater than or equal to the initial second RSRP threshold, the transmission quality of the transmission by the user device 101 using the CG-SDT mechanism can reach a best match state with the CG-SDT resources configured by the network device; as the at least one SDT RSRP threshold is continuously lowered, it may result in a reduction in the transmission quality of transmissions using the CG-SDT mechanism. In this way, in the embodiment of the present application, a threshold value and a frequency threshold value are set, before the current at least one SDT RSRP threshold value is turned down, it is determined that the frequency of turning down the at least one SDT RSRP threshold value is smaller than the frequency threshold value, and/or it is determined that the current at least one SDT RSRP threshold value is greater than the threshold value, and only when the frequency of turning down the at least one SDT RSRP threshold value is smaller than the frequency threshold value and/or the current at least one SDT RSRP threshold value is greater than the threshold value, the current at least one SDT RSRP threshold value is turned down. Therefore, the transmission quality can be ensured while the probability of adopting the CG-SDT mechanism for transmission is improved.

In the embodiment of the present application, different SDT RSRP threshold values correspond to different frequency thresholds or to the same frequency threshold. In the embodiment of the present application, different SDT RSRP thresholds may correspond to different threshold values, or may correspond to the same threshold value.

In the embodiment of the present application, the threshold type included in the at least one SDT RSRP threshold is not limited. In some embodiments, the at least one SDT RSRP threshold value comprises a first RSRP threshold value that is an average threshold value of RSRP of the configured SSB; in other embodiments, the at least one SDT RSRP threshold includes a second RSRP threshold that is an RSRP threshold of any one of the configured SSBs.

In this embodiment of the present application, the user equipment 101 may adjust down some or all SDTRSRP threshold values in the at least one SDT RSRP threshold value based on determining that transmitting the data packet using the RA-SDT mechanism fails at least once, which is not limited in this embodiment of the present application. Illustratively, as described above, the at least one SDTRSRP threshold includes a first RSRP threshold and a second RSRP threshold, and if transmitting the data packet using the RA-SDT mechanism fails at least once, the user equipment 101 may adjust the first RSRP threshold, may also adjust the second RSRP threshold, and may also adjust the first RSRP threshold and the second RSRP threshold.

In this embodiment of the present application, the amplitude of each SDT RSRP threshold is not limited, and the amplitude of the first RSRP threshold and the amplitude of the second RSRP threshold that are adjusted down may be the same or different, and the amplitudes of the first RSRP threshold and the second RSRP threshold that are adjusted down may be both determined according to actual requirements; in some embodiments, the first RSRP threshold is turned down by an amplitude M that is greater than 0 and less than the first RSRP threshold, and the second RSRP threshold is turned down by an amplitude K that is greater than 0 and less than the second RSRP threshold.

It may be understood that, in this embodiment of the present application, the ue 101 performs, in time, a lowering operation on the first RSRP threshold value and/or the second RSRP threshold value configured by the network device 102 when transmission using the RA-SDT mechanism fails at least once, so that the average value of RSRP of the configured SSBs is greater than or equal to the lowered first RSRP threshold value and/or the RSRP of at least one SSB of the configured SSBs is greater than the lowered second RSRP threshold value, thereby improving the chance/probability of transmission using the CG-SDT mechanism; thereby being beneficial to improving the utilization rate of resources.

In this embodiment, after the at least one SDT RSRP threshold is adjusted down, the user equipment 101 determines whether to transmit using the CG-SDT mechanism based on the adjusted down at least one SDT RSRP threshold.

In the embodiment of the present application, the basis for the user equipment 101 to adopt the CG-SDT mechanism for transmission is not limited; in some embodiments, the user equipment 101 uses the CG-SDT mechanism for transmission based on determining that the average value of RSRP of configured SSBs is greater than or equal to the first RSRP threshold after throttling down, and that RSRP of at least one of the configured SSBs is greater than or equal to the second RSRP threshold after throttling down, and is configured with CG-SDT resources.

Further, in some embodiments, the user equipment 101 may determine whether the average value of RSRP of the configured SSBs is greater than or equal to the first RSRP threshold after being adjusted down, and determine whether CG-SDT resources are configured, and determine whether the RSRP of at least one of the configured SSBs is greater than or equal to the second RSRP threshold after being adjusted down; in some embodiments, the judging sequence of the three judgments is not limited; for example, the user equipment 101 may first determine whether the average value of RSRP of the configured SSB is greater than or equal to the first RSRP threshold after being adjusted down, and if so, determine whether CG-SDT resources are configured; if yes, still further judging whether the RSRP of at least one SSB in the configured SSBs is larger than or equal to the second RSRP threshold after being regulated down.

In the embodiment of the present application, the basis for the user equipment 101 to adopt non-SDT transmission is not limited; in some embodiments, the user equipment 101 uses a non-SDT mechanism for transmission based on determining that the average value of RSRP of the configured SSB is less than the first RSRP threshold value after throttling down.

In the embodiment of the present application, the basis for the user equipment 101 to adopt RA-SDT mechanism transmission is not limited; in some embodiments, the user equipment 101 employs the RA-SDT mechanism for transmission based on determining that the average value of RSRP of the configured SSB is greater than or equal to the first RSRP threshold value after throttling down and the CG-SDT resources are not configured; in other embodiments, the user equipment 101 uses the RA-SDT mechanism for transmission based on determining that the average value of RSRP of configured SSBs is greater than or equal to the first RSRP threshold after throttling down and that RSRP of at least one of the configured SSBs is less than the second RSRP threshold after throttling down is configured with CG-SDT resources.

It can be understood that the lower the first RSRP threshold value is, the lower the probability that the user equipment 101 adopts a non-SDT mechanism to transmit is, and the lower the second RSRP threshold value is, the lower the probability that the user equipment 101 adopts an RA-SDT mechanism to transmit is, so as to improve the probability that the user equipment 101 adopts CG-SDT resources preconfigured by the network equipment 102 to transmit, which is beneficial to improving the resource utilization.

In step 301a, the packet transmitted by the RA-SDT mechanism is different from the packet transmitted by the CG-SDT mechanism, and the packet transmitted by the RA-SDT mechanism may be the packet currently attempted to be transmitted by the RA-SDT mechanism and failed to be transmitted, and the packet transmitted by the CG-SDT mechanism may be the next packet ready for subsequent transmission.

Based on this, in some embodiments: the user equipment 101 transmits the current data packet using a non-SDT mechanism based on determining that the transmission of the current data packet using the RA-SDT mechanism fails, and decreases the at least one SDT RSRP threshold value; the at least one SDT RSRP threshold after being turned down is used for determining whether to transmit a next data packet by adopting the CG-SDT mechanism. That is, when the data packet is transmitted this time, if contention resolution fails when the target cell is randomly accessed, a non-SDT mechanism is used to transmit the data packet that needs to be transmitted this time.

In this embodiment, the ue 101 may transmit a plurality of data packets in the target cell, after each time of transmitting the failure number by using the RA-SDT mechanism, it is determined whether to lower the current at least one SDT RSRP threshold according to the current accumulated failure number, and if the accumulated failure number is at least one, the current at least one SDT RSRP threshold is lowered, so as to determine whether to use the CG-SDT mechanism for transmitting the next data packet based on the lowered at least one SDT RSRP threshold.

In some embodiments, the procedure for the user equipment 101 to employ RA-SDT mechanism transmission is: the user equipment 101 executes a transmission task, and after the MAC layer randomly accesses the target cell in a contention-based mode, the RRC layer is informed of transmission based on an SDT mechanism; however, in the above procedure, if the ue 101 fails to access the target cell randomly, the transmission task cannot be completed, and the RA-SDT mechanism is adopted to transmit the failure; in case of transmission failure using the RA-SDT mechanism, the MAC layer informs the RRC layer of transmission using the non-SDT mechanism.

Fig. 3B is a schematic implementation flow chart of the data transmission method according to the embodiment of the present application, as shown in fig. 3B, where the data transmission method includes the following steps 301B to 302B:

step 301b, the user equipment 101 lowering at least one SDT RSRP threshold value based on determining that transmission using the RA-SDT mechanism has failed at least once; the at least one SDT RSRP threshold is used for determining whether to adopt a CG-SDT mechanism for transmission;

step 302b, after the user equipment 101 has turned down the at least one SDT RSRP threshold value, determining whether to employ the CG-SDT mechanism for transmission based on the at least one SDT RSRP threshold value after the turning down.

It can be appreciated that, in the embodiment of the present application, the ue 101 performs, in time, a lowering operation on at least one SDT RSRP threshold configured by the network device 102 when transmission using the RA-SDT mechanism fails at least once, so as to enable the opportunity/probability of transmission using the CG-SDT mechanism to be improved when transmission is performed next time, which is further beneficial to reducing power consumption and improving resource utilization.

SDT is introduced for supporting the UE to carry out uplink packet data transmission in an inactive state so as to reduce power consumption, signaling overhead and transmission delay, and can be applied to packet data services such as uploading and pushing of health monitoring data. The packet transfer types include CG-SDT and RA-SDT, and the SDT specific flow is shown in fig. 2.

In fig. 2, after receiving the upper layer packet, the RRC layer notifies the MAC layer of transmission, and the MAC layer first determines whether the packet size is greater than a second threshold, if yes, notifies the RRC layer of non-SDT transmission, if not, continues to determine whether the current RSRP (an example of the average value of the configured RSRP of the SSB) is greater than or equal to the SDT RSRP threshold (an example of the first RSRP threshold), if not, notifies the RRC layer of non-SDT transmission, and if the current RSRP (an example of the average value of the configured RSRP of the SSB) is greater than or equal to the SDT RSRP threshold (an example of the first RSRP threshold), or the SDT RSRP threshold (an example of the first RSRP threshold) is not configured, continues to determine whether CG-SDT resources are configured. If the CG-SDT related resources are carried in an RRC Release (Release) message, determining whether the SSB-RSRP (an example of RSRP of at least one SSB) is greater than or equal to the CG-SDT RSRP threshold (an example of a second RSRP threshold), if so, informing the RRC layer that SDT mechanism transmission may be employed, and if no or no CG-SDT resources are configured, attempting RA-SDT. And (3) performing random access, if the contention resolution is successful, informing the RRC layer that SDT transmission can be performed, and if RA-SDT transmission fails, informing the RRC layer that non-SDT transmission is performed.

In some embodiments, when the number of users in the target cell is large, the network congestion may cause the RA-SDT contention resolution to fail, and in some embodiments, the RA-SDT may be performed even if the network configures CG-SDT resources, such as the average value of RSRP of configured SSBs is greater than or equal to the first RSRP threshold after being turned down and the RSRP of at least one SSB of configured SSBs is less than the second RSRP threshold after being turned down. The UE initiates SDT transmission requests for many times in the congested cell, the SDT cannot be transmitted because CG-SDT contention resolution fails, and only a non-SDT transmission flow can be carried out, in the non-SDT transmission, the RRC layer needs to enter a connection state first, the current network is still in a congestion state, so that the contention resolution of connection establishment fails, data cannot be uploaded, and CG-SDT configured by the network is not fully utilized.

In view of this, the embodiment of the present application further provides a data transmission method, and fig. 4 is a schematic implementation flow chart of the data transmission method provided in the embodiment of the present application, as shown in fig. 4, where the data transmission method includes the following steps 401 to 415:

step 401, the rrc layer receives the upper layer data and notifies the MAC layer of transmission;

step 402, the mac layer determines whether the data size is greater than a second threshold; if yes, go to step 415; otherwise, go to step 403;

Step 403, the mac layer determines whether the network device 102 configures a first RSRP threshold; if yes, go to step 404; otherwise, go to step 405;

step 404, the mac layer determines whether the average value of RSRP of the configured SSB is greater than or equal to a first RSRP threshold value; if yes, go to step 405; otherwise, step 415 is performed;

step 405, the mac layer determines whether the network device 102 configures CG-SDT resources; if yes, go to step 406; otherwise, go to step 407;

step 406, the mac layer determines whether at least one SSB of the configured SSBs is greater than or equal to a second RSRP threshold; if yes, go to step 414; otherwise, go to step 407;

step 407, the mac layer attempts to transmit using RA-SDT mechanism;

step 408, the mac layer determines whether RA is successful; if yes, go to step 414; otherwise, go to step 409;

step 409, the mac layer determines whether the number of failures transmitted by using the RA-SDT mechanism is greater than or equal to a first threshold; if yes, go to step 410; otherwise, step 415 is performed;

step 410, the mac layer determines whether the network device 102 configures CG-SDT resources; if yes, go to step 411; otherwise, step 415 is performed;

step 411, the mac layer decreases the second RSRP threshold by K;

Step 412, the mac layer determines whether the network device 102 configures a first RSRP threshold; if yes, go to step 413; otherwise, step 415 is performed;

in step 413, the mac layer lowers the first RSRP threshold by M, and performs step 415.

In step 414, the mac layer informs the RRC layer of SDT data transmission.

In step 415, the mac layer informs the RRC layer of the non-SDT data transmission.

When the UE fails to transmit RA-SDT in the same target cell, the UE accumulates the failure times, and if the failure times are greater than or equal to a first threshold (the first threshold needs to be determined according to the actual test condition), if CG-SDT resources are configured, the second RSRP threshold is lowered by K, and if the first RSRP threshold is configured, the threshold is lowered by M (the M needs to be determined according to the actual test condition), and then the RRC is notified to perform non-SDT transmission. When there is an SDT transmission requirement in the cell next time, due to the decrease of the first RSRP threshold value and the second RSRP threshold value, CG-SDT is executed with more possibility to meet CG-SDT check conditions. Because the SDT configurations of different cells are different, the accumulation of failure times and the lowering of at least one SDT RSRP threshold value are only applicable to the situation that the target cell is unchanged, and the cell needs to be emptied when the cell is changed.

It can be understood that in the case that the target cell is unchanged, the embodiment of the application can judge that the current network is likely to be in a congestion state according to the number of times of adopting RA-SDT transmission failure, and further perform feedback adjustment on the first RSRP threshold value and/or the second RSRP threshold value, dynamically adjust to meet the RSRP condition of CG-SDT, and fully utilize the network preconfigured resource to make CG-SDT under the condition that RSRP is still available, thereby avoiding the negative effects of increased power consumption, prolonged time delay and the like caused by making a small amount of data into non-SDT, and avoiding the data unable to be uploaded caused by the network always being in the congestion state.

In the embodiment of the application, the UE actively adjusts the first RSRP threshold value and the second RSRP threshold value, and reduces the condition of meeting the CG-SDT under the condition that the RA-SDT transmission fails at least once, so that the UE can fully utilize network pre-configuration resources to make the CG-SDT when transmitting the small packet.
