Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of communication, and particularly relates to a processing method and device of configuration of configured grant, equipment and storage medium. BACKGROUND

[0002] Rel-15 and Rel-16 support configured grant (CG) transmission to meet the high reliability and low latency requirements of ultra-reliable and low latency communications (URLLC) services. When the data packet of the UE arrives, the UE selects a CG configuration for the initial transmission of data.

[0003] When the network detects that the data transmitted on the CG has an error, the retransmission of the data is dynamically scheduled by downlink control information (DCI). The dynamic scheduling in this case is different from the direct dynamic scheduling of the network side. The power control parameters of the physical uplink shared channel (PUSCH) of the retransmission scheduling, such as the target power P0, the path loss compensation factor alpha, and the path loss reference signal (PL-RS) index, continue to use the set of configurations of the CG.

[0004] In a multi-transmitting receiving point (MTRP) scenario, the CG PUSCH can use multiple sets of parameters, and the prior art cannot implement multiple sets of parameter indication. When the CG link is blocked / occluded, the network side can dynamically schedule the retransmission of the data to another transmitting receiving point (TRP) by using DCI. At this time, the beam, channel, and target power P0 of the target TRP of the transmission will change significantly. If the prior art solution is continued to be used, the retransmission PUSCH scheduled by the DCI still uses the power control parameters of the CG configuration, which will cause the transmission power of the UE to be too high or too low for the retransmission data. Too high will cause interference to other users, and too low will reduce the reception performance of the retransmission data, and in serious cases, cause the retransmission to fail. The network continuously schedules the retransmission data to cause a large load, and multiple retransmissions will bring a large delay. SUMMARY

[0215] Optionally, the network side configures one or more power offset values for the UE, which can be positive or negative.

[0216] Optionally, the transmission power of the retransmission PUSCH is provided by the SRI-PUSCH-PowerControl mapped by the SRI field of the DCI.

[0217] Optionally, the UE calculates the transmission power according to the parameters provided by the SRI-PUSCH-PowerControl and superimposes the power offset value configured by the network side as the final transmission power.

[0218] 3.1.3 The high-level signaling indicates whether the retransmission power control parameters of the terminal CG are configured by CG or indicated by DCI.

[0219] Optionally, the higher-layer signaling is RRC or MAC CE.

[0220] When the CG is not configured with power control parameters and the higher-layer signaling does not indicate the retransmission power control parameters of the terminal CG, the DCI is used to indicate the power control parameters.

[0221] The methods in the above embodiments are further illustrated below with several specific examples:

[0222] Example 1:

[0223] Figure 3 This is one of the schematic diagrams illustrating the configuration authorization method provided in the embodiments of this application, such as... Figure 3 As shown, the network side configures two SRS resource sets for the UE. The SRS resource indicated by the srs-ResourceIndicator configured in the CG or the SRI field of the activated DCI belongs to the first SRS resource set, and the corresponding beam points to TRP1. The power parameters configured in the CG match the target receiving TRP, i.e., TRP1, including the target received power P0, the path loss reference signal PL-RS for calculating path loss, and the closed-loop power control adjustment state l. When the data transmission fails, the network side dynamically schedules the retransmission of the data through the DCI. The SRS resource indicated by the SRI field of the DCI belongs to the second SRS resource set, and the beam points to TRP2. When the UE sends the retransmission PUSCH, the power control parameters are matched with the target TRP, i.e., TRP2. At this time, the UE can directly use the SRI-PUSCH-powerControl mapped by the SRI value of the scheduling DCI, which provides P0 / α, PL-RS, and the closed-loop power control index.

[0224] The UE can also continue to use the power control reference signal configured in the CG. However, due to beam changes, the path loss measured by the retransmission PUSCH might be relatively large, resulting in higher UE transmit power and interference to other users. Therefore, the network can configure a negative power offset value for the CG, adding this power offset value to the power calculated based on the CG parameters. This ensures that the power received by the base station is approximately the same as the power of data arriving at the base station from other users.

[0225] Example 2:

[0226] Figure 4 This is the second schematic diagram of the configuration authorization method provided in the embodiments of this application, as shown below. Figure 4As shown, a CG is configured with two sets of SRS-ResourceIndicators, or the SRI field of the activated DCI indicates that the SRS belongs to two SRS resource sets, corresponding to two beams pointing to TRP1 and TRP2 respectively. Two sets of power control parameters are configured corresponding to the two SRIs. When an error occurs in the initial data transmission on the CG, the network dynamically schedules the retransmission of this data through the DCI. If the SRS resources indicated by the SRI in the scheduling DCI belong to the same SRS resource set, then when the UE sends the retransmission PUSCH, the power control uses the power control parameters associated with the second SRI, because the SRS resource set where the SRS indicated by the SRI field in the dynamic scheduling DCI belongs is the same resource set as the SRS resource set indicated by the second SRI in the CG.

[0227] This approach allows the continued use of the CG's power control parameters, ensuring the performance of data transmission from the CG to the TRP.

[0228] Example three:

[0229] Figure 5 The third schematic diagram of the configuration authorization method provided in the embodiments of this application is as follows: Figure 5 As shown, a CG is configured with two SRIs, indicating SRSs belonging to two SRS resource sets, corresponding to two beams pointing to TRP1 and TRP2 respectively. Two sets of power control parameters are configured corresponding to the two SRIs. When an error occurs in the initial data transmission on the CG, the network dynamically schedules the retransmission of this data through DCI. The SRS resources indicated by the SRIs in the scheduling DCI belong to two SRS resource sets. At this time, when the UE sends a retransmission PUSCH, it uses the two sets of power control parameters corresponding to the CG.

[0230] Example 4:

[0231] Figure 6 The fourth schematic diagram of the configuration authorization method provided in the embodiments of this application is as follows: Figure 6 As shown, a CG is configured with a set of SRS-ResourceIndicators, indicating SRS resources belonging to different SRS resource sets. Initial data transmission occurs on two CGs, each with a corresponding beam pointing to TRP1 and TRP2 respectively. When an error occurs in the initial data transmission on a CG, the network dynamically schedules a retransmission of the data via a DCI. If the SRS resources indicated by the SRI in the scheduling DCI belong to the same SRS resource set, then when the UE sends the retransmission PUSCH, the power control uses the power control parameters of CG1, because the SRS resource set indicated by the SRI field in the dynamic scheduling DCI is the same as the SRS resource set indicated by the SRI in CG1.

[0232] Example five:

[0233] Figure 7 As shown in a fifth configuration mode of the configuration of the configured grant provided in the embodiments of the present application, Figure 7 a set of srs-ResourceIndicator is configured in one CG, the initial transmission of data occurs on two CGs, and the SRS resources indicated by the srs-ResourceIndicator of the two CGs belong to different SRS resource sets, corresponding to two beams respectively pointing to TRP1 and TRP2. When the initial transmission of data on the CG occurs error, the network dynamically schedules the retransmission of the data through two DCIs from CORESETs associated with different CORESETPoolIndex, and the SRS resources indicated by the SRI in the scheduling DCIs belong to different SRS resource sets. When the UE transmits the retransmission PUSCH, the power control parameters are configured in the CG. PUSCH1 is scheduled by the DCI from the CORESET associated with CORESETPoolIndex=0, and the power control parameters corresponding to PUSCH1 adopt the parameters in CG1 associated with CORESETPoolIndex=0. Similarly, PUSCH2 adopts the configuration of CG2. The power control parameters here include P0 / α, PL-RS, and closed-loop power control state index l.

[0234] Example six:

[0235] Figure 8 As shown in a sixth configuration mode of the configuration of the configured grant provided in the embodiments of the present application, Figure 8 a set of srs-ResourceIndicator is configured in one CG, the initial transmission of data occurs on two CGs, and the SRS resources indicated by the srs-ResourceIndicator of the two CGs belong to different SRS resource sets, corresponding to two beams respectively pointing to TRP1 and TRP2. The two CGs are respectively associated with different CORESETPoolIndex. When the initial transmission of data on the CG occurs error, the network dynamically schedules the retransmission of the data through two DCIs from CORESETs associated with different CORESETPoolIndex, and the SRS resources indicated by the SRI in the scheduling DCIs belong to different SRS resource sets. When the UE transmits the retransmission PUSCH, the power control parameters are configured in the CG. PUSCH1 is scheduled by the DCI from the CORESET associated with CORESETPoolIndex=0, and the power control parameters corresponding to PUSCH1 adopt the parameters in CG1 associated with CORESETPoolIndex=0. Similarly, PUSCH2 adopts the configuration of CG2. The power control parameters here include P0 / α, PL-RS, and closed-loop power control state index l.
