Currently, in a multi-transmission and reception point (Transmission and Reception Point, TRP) scenario, a Physical Uplink Shared Channel (PUSCH) repetition transmission scheme in a Time Division Multiplexing (TDM) manner for dynamic scheduling of Downlink Control Information (DCI) is supported. For Configured Grant (CG) scheduling, multi-TRP repetition transmission is also supported by using one CG configuration. However, when quantities of Sounding Reference Signal (SRS) resource sets configured for different DCI formats are different, how to determine a transmission manner of a type 1 CG is an urgent problem to be resolved.

Therefore, when the quantities of SRS resource sets configured for the at least two DCI formats are different or only the one DCI format is configured, the UE can accurately determine the transmission manner of the CG, so that the UE transmits the PUSCH of the CG.

The following describes some concepts and/or terms in a CG transmission method and apparatus, user equipment, and a storage medium provided in the embodiments of this application.
Currently, in a multi-TRP scenario, a PUSCH repetition transmission scheme in a time division multiplexing (TDM) manner for dynamic scheduling by DCI is supported. For each PUSCH repetition, a plurality of transmit beams corresponding to different TRPs are used respectively, for example, a spatial relation (spatial relation information) is indicated by an SRS resource indicator (SRI) field or a transmit beam is indicated by an uplink Transmission Configuration Indicator (TCI) field to perform sending, thereby improving reliability of PUSCH transmission.
For PUSCH repetition of Type A (slot-level), one PUSCH repetition is one PUSCH transmission occasion in each slot. For PUSCH repetition of Type B, one PUSCH repetition is nominal repetition. For example, DCI may include two SRI indicators, a transmission precoding matrix and layer indicator (Transmit precoding matrix indicator, TPMI), a power control parameter, and the like, and one 2-bit new indicator field is added to the DCI to support dynamic switching between single-TRP (STRP) and multi-TRP (MTRP), and a sequence of transmit beams for PUSCH repetitions is flexibly changed.
For configured grant (CG) scheduling, multi-TRP repetition transmission is also supported by using one CG configuration. A beam or power control mapping mechanism thereof is similar to that of dynamic scheduling, that is, two power control fields are configured in the CG configuration including: two PUSCH P0 and Alpha parameter fields (p0-PUSCH-Alpha) and two closed-loop power control fields (powerControlLoopToUse). A configuration of a type 1 CG includes two transmission configurations (for example, two path loss reference signal indexes (pathlossReferenceIndex), two SRS resource indicators (srs-ResourceIndicator), and two precoding and number of layers indicators (precodingAndNumberOfLayers)). When two SRS resource sets are configured for both DCI format 0_1 and DCI format 0_2, if two SRI indicator fields are configured in the CG, two SRS resources indicated by the two SRIs are associated with two SRS resource sets configured for the DCI format 0_1. If the CG is the Type 1 CG configured with only one power control parameter and transmission parameter, transmission of the CG is associated with the 1st SRS resource set.
Retransmission of the Type 1 CG is dynamically scheduled by DCI.
With reference to the accompanying drawings, the following describes in detail the CG transmission method provided in the embodiments of this application by using some embodiments and application scenarios thereof.
Because SRS resource set(s) are separately configured for DCI formats 0_1 and 0_2, it implies that there can be the case that one SRS resource set is configured for one DCI format and two SRS resource sets are configured for the other DCI format. If two SRS resource sets are configured for the DCI format 0_1 and one SRS resource set is configured for the DCI format 0_2, SRS resource(s) included in the one SRS resource set for the DCI format 0_2 is/are the first NSRS, 0_2 SRS resource(s) in a 1st SRS resource set for the DCI format 0_1. If one SRS resource set is configured for the DCI format 0_1 and two SRS resource sets are configured for the DCI format 0_2, SRS resource(s) included in a 1st SRS resource set for the DCI format 0_2 is/are the first NSRS, 0_2 SRS resource(s) in the SRS resource set for the DCI format 0_1, and SRS resources included in a 2nd SRS resource set for the DCI format 0_2 are without restriction. In some embodiments, only one of the DCI format 0_1 or the DCI format 0_2 may be configured, and one or two SRS resource sets are configured for this configured DCI format; or one or two SRS resource sets are configured for one of the DCI format 0_1 or the DCI format 0_2, and no SRS resource set is configured for the other DCI format. In this case, one or two power control parameters and transmission parameters may be configured for the Type 1 CG, and how to determine an SRS resource set corresponding to a power control parameter and transmission parameter needs to be resolved.
In the embodiments of this application, in a case that quantities of SRS resource sets configured for at least two DCI formats are different or only one DCI format is configured, UE may determine target SRS resource set(s) associated with a transmission configuration of a CG according to the SRS resource sets configured for the at least two DCI formats or an SRS resource set configured for the one DCI format, to determine a transmission manner of the CG. That is, the UE uses one or more SRS resources in all SRS resource sets configured for the at least two DCI formats as an SRS resource set for transmitting a PUSCH of the CG or uses one or more SRS resources in all SRS resource sets configured for the only one configured DCI format as an SRS resource set for transmitting a PUSCH of the CG. Therefore, when the quantities of SRS resource sets configured for the at least two DCI formats are different or only the one DCI format is configured, the UE can accurately determine the transmission manner of the CG, so that the UE transmits the PUSCH of the CG.
An embodiment of this application provides a CG transmission method.
Step 201: In a case that quantities of SRS resource sets configured for at least two DCI formats are different or only one DCI format is configured, UE determines target SRS resource set(s) associated with a transmission configuration of a CG according to the SRS resource sets configured for the at least two DCI formats or an SRS resource set configured for the one DCI format.
In this embodiment of this application, that quantities of SRS resource sets configured for at least two DCI formats are different or only one DCI format is configured may be understood as follows: In one case, the SRS resource sets are configured for the at least two DCI formats, and the quantities of SRS resource sets configured for the at least two DCI formats are different (for example, one SRS resource set is configured for a first DCI format, and two SRS resource sets are configured for a second DCI format, or two SRS resource sets are configured for a first DCI format, and one SRS resource set is configured for a second DCI format). In another case, no SRS resource set is configured for one DCI format of the at least two DCI formats, and at least one SRS resource set is configured for another DCI format (for example, no SRS resource set is configured for a first DCI format, and one SRS resource set or two SRS resource sets are configured for a second DCI format, or one SRS resource set or two SRS resource sets are configured for a first DCI format, and no SRS resource set is configured for a second DCI format). In still another case, a network side device configures only one DCI format (for example, a first DCI format or a second DCI format) in the at least two DCI formats and does not configure another DCI format of the at least two DCI formats, and configures at least one SRS resource set for the one DCI format (for example, only a first DCI format is configured, and one SRS resource set or two SRS resource sets are configured for the first DCI format; or only a second DCI format is configured, and one SRS resource set or two SRS resource sets are configured for the second DCI format).
It should be noted that quantities of SRS resource sets configured for at least two DCI formats are different may be understood as follows: Quantities of SRS resource sets configured for all of the at least two DCI formats are different, or quantities of SRS resource sets configured for a part of the at least two DCI formats are different.
It should be noted that the at least two DCI formats include a first DCI format and a second DCI format. The at least two DCI formats may further include DCI in other different formats, and this is not limited in this embodiment of this application. The only one configured DCI format in this embodiment of this application is one DCI format of the at least two DCI formats.
In this embodiment of this application, the first DCI format may be a DCI format 0_1, and the second DCI format may be a DCI format 0_2. The first DCI format and the second DCI format may be DCI in other different formats, and this is not limited in this embodiment of this application.
In this embodiment of this application, an SRS resource set configured for the first DCI format is configured by using a higher-layer parameter srs-ResourceSetToAddModList, and an SRS resource set configured for the second DCI format is configured by using a higher-layer parameter srs-ResourceSetToAddModListDCI-0-2.
In this embodiment of this application, an SRS resource set may include at least one SRS resource. For example, the SRS resource sets configured for the at least two DCI formats include an SRS resource set 1, an SRS resource set 2, an SRS resource set 3, and an SRS resource set 4, where the SRS resource set 1 includes N1 SRS resources, the SRS resource set 2 includes N2 SRS resources, the SRS resource set 3 includes N3 SRS resources that are the first N3 SRS resources in the SRS resource set 1, and the SRS resource set 4 includes N4 SRS resources that are the first N4 SRS resources in the SRS resource set 2.
In this embodiment of this application, the CG may be a CG of a target type, for example, a CG of a type 1 or a CG of another type.
In this embodiment of this application, the transmission configuration of the CG includes at least one of the following: precoding and number of layers information (for example, a precoding and number of layers indicator field (precodingAndNumberOfLayers)), SRS resource indication information (for example, an SRS resource indicator field (srs-ResourceIndicator)), power control information (for example, a P0 and Alpha parameter field (p0-PUSCH-Alpha)), a closed-loop power control field (powerControlLoopToUse), a path loss reference signal index (pathlossReferenceIndex), or the like.
In this embodiment of this application, the transmission configuration of the CG may be at least one transmission configuration, and each transmission configuration is associated with one SRS resource set, that is, an SRS resource indicated by SRS resource indication information (SRI) is one SRS resource in the corresponding SRS resource set. If the transmission configuration of the CG is one transmission configuration, an SRS resource set associated with the determined transmission configuration of the CG is one SRS resource set. If the transmission configuration of the CG is a plurality of transmission configurations, SRS resource sets associated with the determined transmission configuration of the CG are a plurality of SRS resource sets (the plurality of transmission configurations are associated with the plurality of SRS resource sets in a one-to-one manner).
It should be noted that SRS resource sets associated with the plurality of transmission configurations are different; or SRS resource sets associated with a part of the plurality of transmission configurations are different; or SRS resource sets associated with the plurality of transmission configurations are the same (that is, the plurality of transmission configurations are associated with a same SRS resource set).
It can be understood that the UE may determine an association between the transmission configuration of the CG and an SRS resource set according to status of SRS configurations for different DCI formats, that is, determine the SRS resource set associated with the transmission configuration of the CG.
For example, as shown in Table 1, Table 1 shows an association between SRS resource sets configured for two DCI formats and the transmission configuration of the CG provided in this embodiment of this application.
For example, in the foregoing Table 1, if two SRS resource sets (the SRS resource set 1 and the SRS resource set 2) are configured for the DCI format 0_1, and no SRS resource set is configured for the DCI format 0_2 or the DCI format 0_2 is not configured, in one case, the CG is configured with one transmission configuration, and an SRS resource set associated with the one transmission configuration is the SRS resource set 1 (that is, a 1st SRS resource set) of the SRS resource sets configured for the DCI format 0_1; and in another case, the CG is configured with two transmission configurations, and SRS resource sets associated with the two transmission configurations are the SRS resource set 1 and the SRS resource set 2 (that is, a 1st SRS resource set associated with a 1st transmission configuration and a 2nd SRS resource set associated with a 2nd transmission configuration) of the SRS resource sets configured for the DCI format 0_1. It should be noted that, for other cases in the table (that is, an association between an SRS resource set configured for a DCI format and the transmission configuration of the CG), details are not listed one by one herein.
In this embodiment of this application, if the SRS resource sets configured for all the at least two DCI formats (for example, the DCI format 0_1 and the DCI format 0_2) are two SRS resource sets (for example, the SRS resource set 1 and the SRS resource set 2 are configured for the DCI format 0_1, and the SRS resource set 3 and the SRS resource set 4 are configured for the DCI format 0_2), in one case, the CG is configured with one transmission configuration, and an SRS resource set associated with the one transmission configuration is the SRS resource set 1 (that is, a 1st SRS resource set) of the SRS resource sets configured for the DCI format 0_1; and in another case, the CG is configured with two transmission configurations, and SRS resource sets associated with the two transmission configurations are the SRS resource set 1 and the SRS resource set 2 in the SRS resource sets configured for the DCI format 0_1.
In a first implementation of this embodiment of this application, the transmission configuration of the CG is one transmission configuration. The foregoing step 201 may be implemented by using the following step 201a.
Step 201a: In a case that the transmission configuration of the CG is one transmission configuration, if quantities of SRS resource sets configured for at least two DCI formats are different or only one DCI format is configured, the UE determines a 1st SRS resource set of SRS resource set(s) configured for a target DCI format as the target SRS resource set.
In this embodiment of this application, the target DCI format is the only one configured DCI format or any DCI format of the at least two DCI formats.
It can be understood that in a case that the transmission configuration of the CG is one transmission configuration, if the quantities of SRS resource sets configured for the at least two DCI formats are different, the UE may determine a 1st SRS resource set of SRS resource set(s) configured for any DCI format of the at least two DCI formats as an SRS resource set (that is, the target SRS resource set) associated with the one transmission configuration; or if the only one DCI format (for example, the first DCI format or the second DCI format) is configured, the UE may determine a 1st SRS resource set of SRS resource set(s) configured for the only configured first DCI format as an SRS resource set associated with the one transmission configuration, or determine a 1st SRS resource set of SRS resource set(s) configured for the only configured second DCI format as an SRS resource set associated with the one transmission configuration.
The following describes a specific solution in which the UE determines the target SRS resource set associated with the transmission configuration of the CG in a case that the transmission configuration of the CG is one transmission configuration by using specific implementations (that is, the following manner 1 to manner 4).
In the manner 1 of this embodiment of this application, the foregoing step 201 may be implemented by using the following step 201a1.
Step 201a1: In a case that the transmission configuration of the CG is one transmission configuration, if at least one SRS resource set is configured for a first DCI format of the at least two DCI formats, the UE determines a 1st SRS resource set of the at least one SRS resource set as the target SRS resource set.
It should be noted that, in the foregoing step 201a1, if one SRS resource set is configured for the first DCI format, the 1st SRS resource set is the one SRS resource set.
It can be understood that, in the manner 1, in a case that the quantities of SRS resource sets configured for the at least two DCI formats are different, the 1st SRS resource set of the SRS resource set(s) configured for the first DCI format is the target SRS resource set.
If one SRS resource set is configured for the first DCI format and at least two SRS resource sets are configured or zero SRS resource sets (that is, no SRS resource set is configured for the second DCI format) are configured for the second DCI format, the UE may determine the one SRS resource set (that is, one SRS resource set configured for the first DCI format) as the target SRS resource set (for example, (1e) in the foregoing Table 1).
In some embodiments, if at least two SRS resource sets are configured for the first DCI format and zero SRS resource sets or one SRS resource set is configured for the second DCI format, the UE may determine a 1st SRS resource set of the at least two SRS resource sets (that is, a 1st SRS resource set of the at least two SRS resource sets configured for the first DCI format) as the target SRS resource set (for example, (1a) and (1b) in the foregoing Table 1).
In the manner 2 of this embodiment of this application, the foregoing step 201 may be implemented by using the following step 201a2.
Step 201a2: In a case that the transmission configuration of the CG is one transmission configuration, if no SRS resource set is configured for a first DCI format of the at least two DCI formats or only a second DCI format is configured, the UE determines a 1st SRS resource set of SRS resource set(s) configured for the second DCI format as the target SRS resource set.
It can be understood that in the manner 2, (1) in a case that the quantities of SRS resource sets configured for the at least two DCI formats are different, the 1st SRS resource set of the SRS resource set(s) configured for the second DCI format is the target SRS resource set.
If no SRS resource set is configured for the first DCI format and one SRS resource set is configured for the second DCI format, the UE may determine the one SRS resource set (that is, one SRS resource set configured for the second DCI format) as the target SRS resource set (for example, (1g) in the foregoing Table 1).
In some embodiments, if no SRS resource set is configured for the first DCI format and at least two SRS resource sets are configured for the second DCI format, the UE may determine a 1st SRS resource set of the at least two SRS resource sets as the target SRS resource set (for example, (1d) in the foregoing Table 1).
If one SRS resource set is configured for the second DCI format, the UE may determine the one SRS resource set (that is, one SRS resource set configured for the second DCI format) as the target SRS resource set.
In some embodiments, if at least two SRS resource sets are configured for the second DCI format, the UE may determine a 1st SRS resource set of the at least two SRS resource sets as the target SRS resource set.
In the manner 3 of this embodiment of this application, the foregoing step 201 may be implemented by using the following step 201a3 or step 201a4.
Step 201a3: In a case that the transmission configuration of the CG is one transmission configuration, if at least two SRS resource sets are configured for one DCI format of the at least two DCI formats and no SRS resource set is configured for another DCI format of the at least two DCI formats, the UE determines a 1st SRS resource set of the at least two SRS resource sets as the target SRS resource set.
It can be understood that in the manner 3, in a case that the quantities of SRS resource sets configured for either of the at least two DCI formats are different, if one SRS resource set is not configured for the at least two DCI formats (that is, a quantity of SRS resource sets configured for each of the at least two DCI formats is not one), a 1st SRS resource set in a DCI format for which at least two SRS resource sets are configured is the target SRS resource set.
If at least two SRS resource sets are configured for the first DCI format and no SRS resource set is configured for the second DCI format, the UE may determine a 1st SRS resource set of the at least two SRS resource sets (that is, a 1st SRS resource set of the at least two SRS resource sets configured for the first DCI format) as the target SRS resource set (for example, (1a) in the foregoing Table 1).
In some embodiments, if at least two SRS resource sets are configured for the second DCI format and no SRS resource set is configured for the first DCI format, the UE may determine a 1st SRS resource set of the at least two SRS resource sets (that is, a 1st SRS resource set of the at least two SRS resource sets configured for the second DCI format) as the target SRS resource set (for example, (1d) in the foregoing Table 1).
Step 201a4: In a case that the transmission configuration of the CG is one transmission configuration, if only the one DCI format is configured and at least two SRS resource sets are configured for the one DCI format, the UE determines a 1st SRS resource set of the at least two SRS resource sets as the target SRS resource set.
It can be understood that if only a first DCI format is configured and at least two SRS resource sets are configured for the first DCI format, the UE determines a 1st SRS resource set of the at least two SRS resource sets (that is, a 1st SRS resource set of the at least two SRS resource sets configured for the first DCI format) as the target SRS resource set; or if only a second DCI format is configured and at least two SRS resource sets are configured for the second DCI format, the UE determines a 1st SRS resource set of the at least two SRS resource sets (that is, a 1st SRS resource set of the at least two SRS resource sets configured for the second DCI format) as the target SRS resource set.
In the manner 4 of this embodiment of this application, the foregoing step 201 may be implemented by using the following step 201a5.
Step 201a5: In a case that the transmission configuration of the CG is one transmission configuration, if one SRS resource set is configured for one DCI format of the at least two DCI formats, the UE determines the one SRS resource set as the target SRS resource set.
It can be understood that, in the manner 4, in a case that the quantities of SRS resource sets configured for the at least two DCI formats are different, an SRS resource set for a DCI format for which only one SRS resource set is configured is the target SRS resource set.
If one SRS resource set is configured for the first DCI format and no SRS resource set or at least two SRS resource sets are configured for the second DCI format, the UE may determine the one SRS resource set (that is, one SRS resource set configured for the first DCI format) as the target SRS resource set (for example, (1e) in the foregoing Table 1).
In some embodiments, if one SRS resource set is configured for the second DCI format and no SRS resource set or at least two SRS resource sets are configured for the first DCI format, the UE may determine the one SRS resource set (that is, one SRS resource set configured for the second DCI format) as the target SRS resource set (for example, (1c) and (1g) in the foregoing Table 1). In a second implementation of this embodiment of this application, the transmission configuration of the CG is at least two transmission configurations. The foregoing step 201 may be implemented by using the following step 201b or step 201c.
Step 201b: In a case that the transmission configuration of the CG is at least two transmission configurations, if no SRS resource set is configured for one DCI format of the at least two DCI formats and one SRS resource set is configured for another DCI format of the at least two DCI formats, the UE determines the one SRS resource set as an SRS resource set associated with a 1st transmission configuration and a 2nd transmission configuration of the at least two transmission configurations.
It can be understood that in a case that the transmission configuration of the CG is at least two transmission configurations, if there is no SRS resource set for the first DCI format (that is, no SRS resource set is configured for the first DCI format or the first DCI format is not configured) and only one SRS resource set is configured for the second DCI format, the UE may determine the one SRS resource set (that is, one SRS resource set configured for the second DCI format) as an SRS resource set associated with the at least two transmission configurations, that is, an SRS resource set associated with each transmission configuration of the at least two transmission configurations is one SRS resource set configured for the second DCI format; or if there is no SRS resource set for the second DCI format (that is, no SRS resource set is configured for the second DCI format or the second DCI format is not configured) and only one SRS resource set is configured for the first DCI format, the UE may determine the one SRS resource set (that is, one SRS resource set configured for the first DCI format) as an SRS resource set associated with the at least two transmission configurations, that is, an SRS resource set associated with each transmission configuration of the at least two transmission configurations is one SRS resource set configured for the first DCI format.
Step 201c: In a case that the transmission configuration of the CG is at least two transmission configurations, if only the one DCI format is configured and one SRS resource set is configured for the one DCI format, the UE determines the one SRS resource set as an SRS resource set associated with a 1st transmission configuration and a 2nd transmission configuration of the at least two transmission configurations.
It can be understood that in a case that the transmission configuration for the CG is at least two transmission configurations, if only the first DCI format is configured and only one SRS resource set is configured for the first DCI format, the UE may determine the one SRS resource set (that is, one SRS resource set configured for the first DCI format) as an SRS resource set associated with the at least two transmission configurations, that is, an SRS resource set associated with each transmission configuration of the at least two transmission configurations is one SRS resource set configured for the first DCI format; or if only the second DCI format is configured and only one SRS resource set is configured for the second DCI format, the UE may determine the one SRS resource set (that is, one SRS resource set configured for the second DCI format) as an SRS resource set associated with the at least two transmission configurations, that is, an SRS resource set associated with each transmission configuration of the at least two transmission configurations is one SRS resource set configured for the second DCI format.
In a third implementation of this embodiment of this application, the transmission configuration of the CG is at least two transmission configurations. The foregoing step 201 may be implemented by using the following step 201d.
Step 201d: In a case that the transmission configuration of the CG is at least two transmission configurations, if only the one DCI format is configured and at least two SRS resource sets are configured for the one DCI format, the UE determines a 1st SRS resource set of the at least two SRS resource sets configured for the one DCI format as an SRS resource set associated with a 1st transmission configuration of the at least two transmission configurations, and determines a 2nd SRS resource set of the at least two SRS resource sets configured for the one DCI format as an SRS resource set associated with a 2nd transmission configuration of the at least two transmission configurations.
It can be understood that in a case that the transmission configuration of the CG is at least two transmission configurations, if only a first DCI format is configured and at least two SRS resource sets are configured for the first DCI format, the UE may determine a 1st SRS resource set of the at least two SRS resource sets (that is, the at least two SRS resource sets configured for the first DCI format) as an SRS resource set associated with the 1st transmission configuration, and determine a 2nd SRS resource set of the at least two SRS resource sets as an SRS resource set associated with the 2nd transmission configuration; or if only a second DCI format is configured and at least two SRS resource sets are configured for the second DCI format, the UE may determine a 1st SRS resource set of the at least two SRS resource sets (that is, the at least two SRS resource sets configured for the second DCI format) as an SRS resource set associated with the 1st transmission configuration, and determine a 2nd SRS resource set of the at least two SRS resource sets as an SRS resource set associated with the 2nd transmission configuration.
In this embodiment of this application, if at least two SRS resource sets are not configured for either of the at least two DCI formats (that is, a quantity of SRS resource sets configured for each of the at least two DCI formats is not at least two), the UE does not expect the transmission configuration of the CG to be at least two transmission configurations, or the transmission configuration of the CG cannot be at least two transmission configurations. In other words, in a case that there are at least two transmission configurations configured for the transmission configuration of the CG, there is at least one DCI format of at least two DCI formats, where at least two SRS resource sets must be configured for each of the at least one DCI format.
In a fourth implementation of this embodiment of this application, the transmission configuration of the CG is at least two transmission configurations. The foregoing step 201 may be implemented by using the following step 201e.
Step 201e: In a case that the transmission configuration of the CG is at least two transmission configurations, if at least two SRS resource sets are configured for only one DCI format of the at least two DCI formats, the UE determines at least two SRS resource sets of the SRS resource sets configured for the at least two DCI formats as SRS resource sets associated with the at least two transmission configurations.
The at least two transmission configurations are associated, in a one-to-one manner, with the at least two SRS resource sets of the SRS resource sets configured for the at least two DCI formats, that is, a 1st transmission configuration is associated with a 1st SRS resource set, and a 2nd transmission configuration is associated with a 2nd SRS resource set.
It can be understood that, in a case that the transmission configuration of the CG is at least two transmission configurations, if at least two SRS resource sets are configured for one DCI format of the at least two DCI formats, the UE may determine at least two SRS resource sets of the SRS resource sets configured for the one DCI format (that is, a DCI format for which at least two SRS resource sets are configured) of the at least two DCI formats as SRS resource sets associated with the at least two transmission configurations. In this manner, SRS resource sets associated with each transmission configuration of the at least two transmission configurations are different.
The following describes a specific solution in which the UE determines the target SRS resource set associated with the transmission configuration of the CG in a case that the transmission configuration of the CG is at least two transmission configurations by using specific implementations (that is, the following manner 5 to manner 8).
In the manner 5 of this embodiment of this application, the foregoing step 201 may be implemented by using the following step 201e1.
Step 201e1: In a case that the transmission configuration of the CG is at least two transmission configurations, if no SRS resource set is configured for one DCI format of the at least two DCI formats and at least two SRS resource sets are configured for another DCI format of the at least two DCI formats, the UE determines a 1st SRS resource set of the at least two SRS resource sets configured for the another DCI format as an SRS resource set associated with a 1st transmission configuration of the at least two transmission configurations, and determines a 2nd SRS resource set of the at least two SRS resource sets configured for the another DCI format as an SRS resource set associated with a 2nd transmission configuration of the at least two transmission configurations.
It can be understood that, in the manner 5, if no SRS resource set is configured for the first DCI format and at least two SRS resource sets are configured for the second DCI format, the UE determines a 1st SRS resource set of the at least two SRS resource sets configured for the second DCI format as the SRS resource set associated with the 1st transmission configuration, and determines a 2nd SRS resource set of the at least two SRS resource sets configured for the second DCI format as the SRS resource set associated with the 2nd transmission configuration; or if no SRS resource set is configured for the second DCI format and at least two SRS resource sets are configured for the first DCI format, the UE determines a 1st SRS resource set of the at least two SRS resource sets configured for the first DCI format as the SRS resource set associated with the 1st transmission configuration, and determines a 2nd SRS resource set of the at least two SRS resource sets configured for the first DCI format as the SRS resource set associated with the 2nd transmission configuration.
In the manner 6 of this embodiment of this application, the foregoing step 201 may be implemented by using the following step 201e2 or step 201e3.
Step 201e2: In a case that the transmission configuration of the CG is at least two transmission configurations, if one SRS resource set is configured for a first DCI format of the at least two DCI formats and at least two SRS resource sets are configured for a second DCI format of the at least two DCI formats, the UE determines the one SRS resource set as an SRS resource set associated with a 1st transmission configuration of the at least two transmission configurations, and determines a 2nd SRS resource set of the SRS resource sets configured for the second DCI format as an SRS resource set associated with a 2nd transmission configuration of the at least two transmission configurations.
For example, with reference to the foregoing Table 1, for example, (2e) in Table 1, if one SRS resource set (that is, the SRS resource set 1) is configured for the DCI format 0_1, and two SRS resource sets (that is, the SRS resource set 3 and the SRS resource set 4) are configured for the DCI format 0_2, the SRS resource set associated with the 1st transmission configuration is the SRS resource set (that is, the SRS resource set 1) for the DCI format 0_1, and the SRS resource set associated with the 2nd transmission configuration is a 2nd SRS resource set (that is, the SRS resource set 4) for the DCI format 0_2.
Step 201e3: In a case that the transmission configuration of the CG is at least two transmission configurations, if one SRS resource set is configured for a first DCI format of the at least two DCI formats and at least two SRS resource sets are configured for a second DCI format of the at least two DCI formats, the UE determines a 1st SRS resource set of the SRS resource sets configured for the second DCI format as an SRS resource set associated with a 1st transmission configuration of the at least two transmission configurations, and determines a 2nd SRS resource set of the SRS resource sets configured for the second DCI format as an SRS resource set associated with a 2nd transmission configuration of the at least two transmission configurations.
In the manner 7 of this embodiment of this application, the foregoing step 201 may be implemented by using the following step 201e4.
Step 201e4: In a case that the transmission configuration of the CG is at least two transmission configurations, if at least two SRS resource sets are configured for a first DCI format of the at least two DCI formats, the UE determines a 1st SRS resource set of the at least two SRS resource sets configured for the first DCI format as an SRS resource set associated with a 1st transmission configuration of the at least two transmission configurations, and determines a 2nd SRS resource set of the at least two SRS resource sets configured for the first DCI format as an SRS resource set associated with a 2nd transmission configuration of the at least two transmission configurations.
It can be understood that, in the manner 7, if at least two SRS resource sets are configured for the first DCI format and one SRS resource set or zero SRS resource sets are configured for the second DCI format, the UE may separately determine a 1st SRS resource set and a 2nd SRS resource set of the at least two SRS resource sets configured for the first DCI format as the SRS resource set associated with the 1st transmission configuration and the SRS resource set associated with the 2nd transmission configuration (for example, (2a) and (2b) in the foregoing Table 1).
In the manner 8 of this embodiment of this application, the foregoing step 201 may be implemented by using the following step 201e5.
Step 201e5: In a case that the transmission configuration of the CG is at least two transmission configurations, if at least two SRS resource sets are configured for any one DCI format of the at least two DCI formats, the UE determines a 1st SRS resource set of the at least two SRS resource sets configured for the any one DCI format as an SRS resource set associated with a 1st transmission configuration of the at least two transmission configurations, and determines a 2nd SRS resource set of the at least two SRS resource sets configured for the any one DCI format as an SRS resource set associated with a 2nd transmission configuration of the at least two transmission configurations.
It can be understood that, in the manner 8, if at least two SRS resource sets are configured for one DCI format and one SRS resource set or zero SRS resource sets are configured for another DCI format (for example, at least two SRS resource sets are configured for the second DCI format and the first DCI format is not configured, or at least two SRS resource sets are configured for the second DCI format and one SRS resource set or zero SRS resource sets are configured for the first DCI format), the UE may separately determine a 1st SRS resource set and a 2nd SRS resource set of the at least two SRS resource sets configured for the one DCI format as the SRS resource set associated with the 1st transmission configuration and the SRS resource set associated with the 2nd transmission configuration. In other words, if two SRS resource sets are configured for only one DCI format, the 1st transmission configuration is associated with a 1st SRS resource set for the DCI format, and the 2nd transmission configuration is associated with a 2nd SRS resource set for the DCI format (for example, (2a), (2b), (2c), and (2d) in the foregoing Table 1).
For example, with reference to the foregoing Table 1, for example, (2c) in Table 1, if no SRS resource set is configured for the DCI format 0_1 and two SRS resource sets are configured for the DCI format 0_2 (that is, the SRS resource set 3 and the SRS resource set 4), the SRS resource set associated with the 1st transmission configuration is a 1st SRS resource set (that is, the SRS resource set 3) for the DCI format 0_2, and the SRS resource set associated with the 2nd transmission configuration is a 2nd SRS resource set (that is, the SRS resource set 4) for the DCI format 0_2.
In another implementation of this embodiment of this application, the transmission configuration of the CG is one transmission configuration. The foregoing step 201 may be implemented by using the following step 201f or step 201g.
Step 201f: In a case that the transmission configuration of the CG is one transmission configuration, configure at least one SRS resource set for the target DCI format of the two DCI formats.
In some embodiments, the target DCI is a DCI format 0_1.
It can be understood that in a case that the transmission configuration of the CG is one transmission configuration, the terminal does not expect that no SRS resource set is configured for the DCI format 0_1.
Step 201g: In a case that the transmission configuration of the CG is one transmission configuration, when no SRS resource set is configured for the target DCI format, a terminal ignores target parameter indication(s) in the transmission configuration of the CG.
In some embodiments, the target parameter indication(s) is/are at least one of the following: an SRI (srs-ResourceIndicator) or a TPMI (precodingAndNumberOfLayers).
In a fifth implementation of this embodiment of this application, the transmission configuration of the CG is two transmission configurations. The foregoing step 201 may be implemented by using the following step 201h or step 201i.
Step 201h: In a case that the transmission configuration of the CG is two transmission configurations, configure at least two SRS resource sets for the target DCI format of the two DCI formats.
In some embodiments, the target DCI is a DCI format 0_1.
It can be understood that in a case that the transmission configuration of the CG is two transmission configurations, the terminal does not expect that one SRS resource set or no SRS resource set is configured for the DCI format 0_1.
Step 201i: In a case that the transmission configuration of the CG is two transmission configurations, when only one SRS resource set is configured for the target DCI format, a terminal ignores a 2nd transmission configuration of the CG.
In some embodiments, the 2nd transmission configuration is at least one of the following: a second SRI (srs-ResourceIndicator2) or a second TPMI (precodingAndNumberOfLayers2).
In a sixth implementation of this embodiment of this application, the foregoing step 201 may be implemented by using the following step 201j or step 201k.
Step 201j: When no SRS resource set is configured for the target DCI format, a terminal transmits the CG by using a single-antenna port.
In some embodiments, the target DCI is a DCI format 0_1.
In some embodiments, step 201j may be used together with step 201g. When no SRS resource set is configured for the target DCI format, the terminal ignores target parameter indication(s) in the transmission configuration of the CG, and transmits the CG by using a single-antenna port.
Step 201k: When no SRS resource set is configured for a target DCI format, determine SRS resource set(s) in a target configuration as the SRS resource set.
In some embodiments, the target configuration is an RRC release configuration.
Step 202: The UE transmits a PUSCH of the CG according to the transmission configuration of the CG and the target SRS resource set.
In this embodiment of this application, the target SRS resource set is used by the UE to transmit an uplink data channel of the CG.
According to the CG transmission method provided in this embodiment of this application, in a case that quantities of SRS resource sets configured for at least two DCI formats are different or only one DCI format is configured, UE may determine target SRS resource set(s) associated with a transmission configuration of a CG according to the SRS resource sets configured for the at least two DCI formats or an SRS resource set configured for the one DCI format, to determine a transmission manner of the CG. That is, the UE uses one or more SRS resources of all SRS resource sets configured for the at least two DCI formats as an SRS resource set for transmitting a PUSCH of the CG or uses one or more SRS resources of all SRS resource sets configured for the only one configured DCI format as an SRS resource set for transmitting a PUSCH of the CG. Therefore, when the quantities of SRS resource sets configured for the at least two DCI formats are different or only the one DCI format is configured, an association between the transmission configuration of the CG and an SRS resource set makes the protocol more complete. In this way, when the quantities of SRS resource sets configured for the at least two DCI formats are different or only the one DCI format is configured, the UE can accurately determine the transmission manner of the CG, so that the UE transmits the PUSCH of the CG.
It should be noted that, the CG transmission method provided in this embodiment of this application may be performed by a CG transmission apparatus, or a control module that is in the CG transmission apparatus and that is configured to perform the CG transmission method.
