The wireless terminal device may communicate with one or more Core Networks (CNs) via a radio access Network (Radio Access Network, RAN), which may be mobile terminal devices such as mobile phones (or "cellular" phones) and computers with mobile terminal devices, e.g., portable, pocket, hand-held, computer-built-in or vehicle-mounted mobile devices that exchange voice and/or data with the radio access Network. Such as personal communication services (Personal Communication Service, PCS) phones, cordless phones, session initiation protocol (Session Initiated Protocol, SIP) phones, wireless local loop (Wireless Local Loop, WLL) stations, personal digital assistants (Personal Digital Assistant, PDAs), and the like. The wireless terminal device may also be referred to as a system, subscriber unit (subscriber unit), subscriber station (subscriber station), mobile station (mobile), remote station (remote station), access point (access point), remote terminal device (remote terminal), access terminal device (access terminal), user terminal device (user terminal), user agent (user agent), user equipment (user device), and embodiments of the present application are not limited in this respect.

The network device according to the embodiment of the present application may be a base station, where the base station may include a plurality of cells for providing services for the terminal. A base station may also be called an access point or may be a device in an access network that communicates over the air-interface, through one or more sectors, with wireless terminal devices, or other names, depending on the particular application. The network device may be operable to exchange received air frames with internet protocol (Internet Protocol, IP) packets as a router between the wireless terminal device and the rest of the access network, which may include an Internet Protocol (IP) communication network. The network device may also coordinate attribute management for the air interface. For example, the network device according to the embodiment of the present application may be a network device (Base Transceiver Station, BTS) in a global system for mobile communications (Global System for Mobile communications, GSM) or code division multiple access (Code Division Multiple Access, CDMA), a network device (NodeB) in a wideband code division multiple access (Wide-band Code Division Multiple Access, WCDMA), an evolved network device (evolutional Node B, eNB or e-NodeB) in a long term evolution (long term evolution, LTE) system, a 5G base station (gNB) in a 5G network architecture (next generation system), a home evolved base station (Home evolved Node B, heNB), a relay node (relay node), a home base station (femto), a pico base station (pico), etc., which are not limited in the embodiment of the present application. In some network structures, the network device may include a Centralized Unit (CU) node and a Distributed Unit (DU) node, which may also be geographically separated.

Multiple-input Multiple-output (Multi Input Multi Output, MIMO) transmissions may each be made between a network device and a terminal device using one or more antennas, and the MIMO transmissions may be Single User MIMO (SU-MIMO) or Multiple User MIMO (MU-MIMO). The MIMO transmission may be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO, or may be diversity transmission, precoding transmission, beamforming transmission, or the like, depending on the form and number of the root antenna combinations.

When the PUSCH is independently scheduled by using the multi-DCI framework, or the PUSCH is simultaneously transmitted by a plurality of CG configurations, or the PUSCH is simultaneously transmitted by a plurality of SRS resource sets, if the plurality of SRS resource sets are configured, the terminal device cannot determine on which SRS resource set the SRI indicated by the SRI in the DCI or in the CG configuration acts, which results in that correct transmission of the PUSCH cannot be effectively ensured, and transmission performance is reduced.

For example, when the PUSCH is independently scheduled by using the multi-DCI framework, the SRS resource set determined by the terminal device may be inconsistent with the SRS resource set understood by the network side, so that correct transmission of the PUSCH cannot be effectively guaranteed. For another example, when the terminal device transmits PUSCH simultaneously through multiple CG configurations, if it is determined that all CG configurations are associated with the first SRS resource set, since each SRS resource set is typically associated with one panel (antenna panel), it may cause the terminal device to perform PUSCH simultaneous transmission only using a single panel, resulting in a degradation of PUSCH transmission performance.

In view of this, the embodiments of the present application provide a PUSCH transmission method, apparatus, and storage medium.

In the embodiment of the present application, the terminal device may understand the SRS resource set for transmitting PUSCH according to a predefined rule, that is, determine on which PUSCH the SRS resource set acts. In this way, when the PUSCH is independently scheduled through the multi-DCI framework, the network equipment and the terminal equipment can be ensured to have consistent understanding, and correct transmission of the PUSCH can be ensured; when the PUSCH is transmitted through DCI scheduling PUSCH and CG configuration or through a plurality of CG configuration, different SRS resource sets can be determined, so that a plurality of panels can be ensured to transmit simultaneously, and the PUSCH transmission performance is improved.

In another case, which SRS resource set is employed for the terminal device may be indicated by the network device. The indication mode can be displayed or implicit, so that correct transmission of the PUSCH can be ensured, and the transmission performance of the PUSCH is improved.

The following describes a PUSCH transmission method provided by the embodiment of the present application through a specific implementation manner. For ease of understanding, the manner in which the SRS resource set is determined based on predefined rules and/or the SRS resource set is determined based on indications is described below, respectively.

1. Determining SRS resource set based on predefined rules

As shown in fig. 1, a flowchart of a method for determining SRS resource set for a terminal device based on a predefined rule, where the method is applied to a scenario of at least one DCI scheduled physical PUSCH, includes the following steps:

step 101, under the condition that terminal equipment detects SRI in DCI, determining an association relationship between a designated parameter and SRS resource set based on a predefined rule; and in step 102, a set of SRS resources is determined based on the association.

Wherein the predefined rule is used for determining the association relationship between the specified parameter and the SRS resource set; the specified parameters include at least one of: coreetpolindex, CORESET detected for transmission of the DCI or PDCCH (Physical Downlink Control Channel ), transmission configuration indication TCI status configuration, specified information field in the DCI, capability value index of the terminal device. The capability value index is a capability value related to a panel (antenna panel) of the terminal device, and the capability value is used for indicating the maximum SRS antenna port number. For example, in the Rel-17 uplink packet selection scenario, before transmission starts, the terminal device may report a packet-related capability value set index (capability [ set ] index), which may also be simply referred to as a capability value index. Each capability value index includes a maximum supported SRS port number (may also be referred to as a capability value), and the SRS port numbers corresponding to any two capability value indexes are different. The network side device can determine the panel of the terminal with a plurality of SRS ports according to the capability value index reported by the terminal. For example, a terminal device has three panels, each having 2,4 SRS antenna ports, and then the terminal device may report 2 capability value indexes corresponding to the 2 SRS ports and the 4 SRS ports, and after receiving the capability value indexes reported by the terminal device, the network side may determine that the terminal device has at least panels with 2 ports and 4 ports. In Rel-17, the capability value index reported by the terminal can only be used for reporting beam measurement, and when reporting L1-RSRP (Layer 1Reference Signal Received Power ) or L1-SINR (Layer 1Signal to Interference and Noise Ratio, layer1signal to interference plus noise ratio), the terminal device will carry a capability value index to indicate which panel is used for measuring the current measurement value when reporting each CRI/SSBRI (Channel state information-reference signal Resource Indicator/Synchronization Signal Block Resource Indicator, channel state information reference signal resource indicator/synchronization signal block resource indicator) and the corresponding L1-RSRP or L1-SINR.

Example 1), when the specified parameter includes CORESET, determining the SRS resource set based on the association relation:

the CORESET and SRS resource set in the specified parameter have a default association relationship.

In determining the SRS resource set based on the association relationship, it may be implemented as: detecting CORESET for transmitting the DCI or PDCCH; then, an SRS resource set associated with the CORESET is selected from at least one SRS resource set as an SRS resource set for transmitting the PUSCH.

That is, there is a default association between CORESET and SRS resource set, in implementation, CORESET for transmitting the DCI or PDCCH is determined first, and then the SRS resource set of CORESET is determined based on the association.

Example 2), when the specified parameters include CORESET and coresetpoolndex, the SRS resource set is determined based on the association relation:

this case may be implemented as: detecting CORESET for transmitting the DCI or PDCCH; and then selecting an SRS resource set associated with the CORESET or the CORESETPoolIndex of the CORESET from at least one SRS resource set as the SRS resource set for transmitting the PUSCH.

For example, CORESET1 for transmission of the DCI or PDCCH may be determined first, CORESET1 then CORESET1 may be determined, and then the SRS resource set associated with CORESET1 may be selected for subsequent PUSCH transmission.

Example 3), determination of the associative relationship based on CORESET or coresetpoolndex

Whether the predefined rule is the case of example 1) or the case of example 2) above, the association between the specified parameter and the SRS resource set in the predefined rule may be determined based on the configured SRS resource set or based on the capability value index reported by the terminal device.

For example, if the specified parameter includes CORESET, and the association includes an association between CORESET and SRS resource set, determining the association based on the configured SRS resource set may be implemented as:

a. SRS resources based on configurationSet determination of the association relationship

a-1, when the network device configures a certain number of SRS resource sets, the association relationship may be at least one of the following association relationships:

a first specified CORESET, or all CORESETs, associated with one SRS resource set; the first specified CORESET may be a CORESET having a coresetpoil index value of 0, or a CORESET not provided with coresetpoil index, or a CORESET having a coresetpoil index value of 1. When CORESET is not configured with CORESET polindex, the CORESET polindex value of default or equivalent CORESET is 0.

The second specified CORESET is associated with one SRS resource set of the two SRS resource sets configured by the network device, and the third specified CORESET is associated with the other SRS resource set; for example, the second specified CORESET may be a CORESET not configured with corespoolindex or a CORESET having a corespoolindex value of 0, the third specified CORESET may be a CORESET having a corespoolindex value of 1, and the second specified CORESET and the third specified CORESET may be vice versa.

For example, a second specified CORESET is associated with the first SRS resource set and the second SRS resource set, and a third specified CORESET is associated with the third SRS resource set and the fourth SRS resource set. Alternatively, the second specified CORESET is associated with the first SRS resource set and a third SRS resource set, and the third specified CORESET is associated with the second SRS resource set and a fourth SRS resource set. Alternatively, the second specified CORESET is associated with the first SRS resource set through the nth SRS resource set, and the third specified CORESET is associated with the n+1th SRS resource set through the 2n or M SRS resource set. Alternatively, the second specified CORESET is associated with the first SRS resource set, a third SRS resource set, …, to the 2n_1 or 2n+1 th SRS resource set, the third specified CORESET is associated with the 2 nd SRS resource set, the 4 th SRS resource set, …, the 2 nd SRS resource set.

a-2, when the number of SRS resource sets configured by the network side is variable, determining the association relationship according to the number of SRS resource sets configured:

a-2-1, a set of SRS resources is configured:

In the case that the network device configures one SRS resource set for the terminal device, the one SRS resource set is associated with a first specified CORESET or the one SRS resource set is associated with all CORESETs.

a-2-2, two SRS resource sets are configured:

in the case that the network device configures two SRS resource sets for the terminal device, a CORESET with a value of 0 or a CORESET with a value of 0, where the CORESET with a value of 1 corresponds to one SRS resource set in the two SRS resource sets.

For example, if the two SRS resource sets are SRS resource set 1 and SRS resource set 2, respectively, then SRS resource set 1 is associated with coresetpolindex with value 0, and SRS resource set 2 is associated with coresetpolindex with value 1.

a-2-3, a plurality of SRS resource sets are configured

In the case that the network device configures four SRS resource sets for the terminal device, CORESET with a value of 0 or CORESET with a value of 0, which is not configured with CORESET polindex, corresponds to the first SRS resource set and the second SRS resource set, and CORESET with a value of 1 corresponds to the third SRS resource set and the fourth SRS resource set. In summary, when one SRS resource set is configured, the predefined rule specifies that this one SRS resource set is associated with all coreets, or with part of coreets, or with coreets not configured with coretpoolindex, or with CORESETs having a value of 0 from coretpoolindex, or with CORESETs having a value of 1 from coretpoolindex.

When two SRS resource sets are configured, each SRS resource set may default to be associated with one or more CORESET or coresetpoolndex.

When three or more SRS resource sets are configured, a portion of the SRS resource sets may be defaulted to be associated with one or more CORESETs or coresetpooolindices, and so on.

For example, a predefined rule is illustrated how to build up from the number of SRS resource sets. In this example, the following assumptions are made: if the parameters SRS-ResourceSetToAddModList or SRS-ResourceToAddModListDCI-0-2 configure 2 SRS resource sets for the 'codebook' or 'noncodebook' use, then the 1 st SRS resource set is associated with a COESET having a COESETPoolindex value of 0 and the 2 nd SRS resource set is associated with a COESET having a COESETPoolindex value of 1.

In another case, in this embodiment if the parameter SRS-ResourceStokeToAddModList or SRS-ResourceToAddModListDCI-0-2 configures 1 SRS resource set for the 'codebook' or 'noncodebook' use, then the SRS resource set is associated with a CORESETS with a COREset Poolindex value of 0.

In another case, in this embodiment if the parameters SRS-ResourceStokeToAddModList or SRS-ResourceToAddModList DCI-0-2 configure 3 or 4 SRS resource sets for the 'codebook' or 'noncodebook' use, then the 1 st and/or 3 rd SRS resource set is associated with a COREset having a CORESET Pooliindex value of 0 and the 2 nd and/or 4 th SRS resource set is associated with a COREset having a CORESET Pooliindex value of 1.

In the above association, CORESET having a coresetpoirindex value of 0 and coresetpoirindex having a coresetpoirindex value of 1 may be interchanged.

In all embodiments of the present application, a CORESET with a CORESET value of 0 includes both CORESETs with CORESET values of 0 and CORESETs without CORESET parameters.

The nth (n=1, 2,3,4, …) SRS resource sets are all determined according to the low-to-high or high-to-low ordering of the parameters SRS-ResourceSetId, for example, when the higher-layer parameter 'txconfig' is configured as 'codebook', the first SRS resource set is the SRS resource set with the lowest SRS-ResourceSetId value in the SRS resource set with the usage of 'codebook'. When the higher-layer parameter 'txconfig' is configured as 'noncodebook', the first SRS resource set is the SRS resource set having the lowest SRS-ResourceSetId value among the SRS resource sets having the usages of 'noncodebook'.

After the UE detects DCI with an SRI field in a certain CORESET, the SRS resource set associated with CORESET may be determined according to the predefined rule, and further, the corresponding SRS resource and the transmission port of PUSCH may be determined according to the indication of SRI. For example, in determining SRS resource set for transmitting PUSCH, CORESET for transmitting DCI may be detected first, and then, if a predefined rule is an association relationship between CORESET and SRS resource set, SRS resource set for transmitting PUSCH may be determined based on the association relationship. In addition, if the predefined rule is an association relationship between coresetpoolndex and SRS resource set, coresetpoolndex configured for CORESET is acquired based on CORESET where DCI is detected, and then SRS resource set for PUSCH transmission can be determined based on the association relationship. In addition, if CORESET is not configured with CORESET Poolindex, SRS resource set may be determined based on the default value of CORESET Poolindex (i.e., value 0) for CORESET.

b, the association of the parameter coresetpoolndex and SRS resource set can also be established directly.For example:

b-1, in case the network device configures a certain number of SRS resource sets:

a first specified coresetpoindindex value, or all coresetpoindindex values, associated with one SRS resource set; the first specified coresetpoolndex value may be 0 or 1.

The second specified coresetpoinlindex value is associated with a set of SRS resources and the third specified coresetpoinlindex value is associated with a set of SRS resources; for example, the second specified coresetpoinlindex value may be 0 or 1 and the third specified coresetpoinlindex value may be 1 or 0.

The second specified coresetpoinlindex value is associated with the first set of SRS resources and the second set of SRS resources and the third specified coresetpoinlindex value is associated with the third set of SRS resources and the fourth set of SRS resources. Alternatively, the second specified coresetpoolndex value is associated with the first set of SRS resources and a third set of SRS resources, and the third specified coresetpoolndex value is associated with the second set of SRS resources and a fourth set of SRS resources. Alternatively, a second specified coresetpoolndex value is associated with the first SRS resource set to the nth SRS resource set and a third specified coresetpoolndex value is associated with the n+1th SRS resource set to the 2N or M SRS resource set. Alternatively, the second specified coresetpolindex value is associated with the first SRS resource set, the third SRS resource set, …, to the 2n-1 or 2n+1 th SRS resource set, and the third specified coresetpolindex value is associated with the 2 nd SRS resource set, the 4 th SRS resource set, …, and the 2 nd SRS resource set.

b-2, when the number of SRS resource sets configured by the network side is variable, determining the association relationship according to the number of the configured SRS resource sets, including the following cases:

b-2-1, configured with one SRS resource set:

in the case that the network device configures one SRS resource set for the terminal device, the one SRS resource set is associated with a first specified coresetpoolndex value, or the one SRS resource set is associated with all coresetpoolndex values.

b-2-2, two SRS resource sets are configured:

and under the condition that the network equipment configures two SRS resource sets for the terminal equipment, the second appointed CORESETPoolIndex value corresponds to one SRS resource set in the two SRS resource sets, and the third appointed CORESETPoolIndex value corresponds to the other SRS resource set.

b-2-3, four SRS resource sets are configured

And under the condition that the network equipment configures four SRS resource sets for the terminal equipment, the second designated CORESETPoolIndex value corresponds to the first SRS resource set and the second SRS resource set, and the third designated CORESETPoolIndex value corresponds to the third SRS resource set and the fourth SRS resource set.

Under the condition of establishing the association relation between the parameter CORESETPoolIndex and the SRS resource set, the terminal can determine the SRS resource set acted by the DCI according to the CORESETPoolIndex value of the CORESET where the DCI is detected, and further determine that the corresponding SRS resource is used for PUSCH transmission.

c. Determining an association based on capability values：

c-1, reporting a capability value index by the terminal equipment

And under the condition that the terminal equipment reports one capability value index, the capability value index establishes the first relation with a second appointed CORESET or all CORESET, and the capability value index establishes the second relation with an appointed SRS resource set.

When one capability value index is reported, defaulting the capability value index to have a first relation with the CORESET value of 0, or defaulting the one capability value index to all CORESETs; having a first relationship and then the one capability value index and the specified SRS resource set having a second relationship.

Thus, when determining the SRS resource set, the CORESET of the DCI or PDCCH is determined first, then the capability value corresponding to the CORESET is determined based on the first relationship, and then the SRS resource set corresponding to the capability value is determined based on the second relationship.

c-2, reporting multiple capability value indexes by the terminal equipment

For example, in the case that the terminal device reports a plurality of capability value indexes, a part of capability value indexes in the plurality of capability values have a first relationship with CORESET not configured with coreetpolindex or coresupoolindex having a value of 0, the remaining other part of capability value indexes have a first relationship with CORESET having a value of 1, and each capability value has a second relationship with the SRS resource set specified by each capability value. That is, the first value and the second value may be set according to the need, the first value may be 0 or 1, and the second value may be 1 or 0, as long as the first value and the second value distinguish different coresetpoolndex.

For another example, when two capability values are reported, the default first capability value is associated with a CORESET having a coresetpoirindex value of 0 or a CORESET not configured with a parameter coresetpoirindex, and the second capability value is associated with a CORESET having a coresetpoirindex value of 1; alternatively, the default first capability value is associated with a CORESET having a coresetpoirindex value of 1, and the second capability value is associated with a CORESET having a coresetpoirindex value of 0 or a CORESET of unconfigured parameter coresetpoirindex;

when three or more capability values are reported, default 2n_1 (n=1, 2, …) capability values or 2n+1 (n=0, 1,2, …) capability values are associated with CORESET having CORESET value 0 or CORESET not configured with parameter CORESET, and 2n (n=0, 1,2, … or n=1, 2, …) capability values are associated with CORESET having CORESET value 1; or default 2n (n=0, 1,2, … or n=1, 2, …) capability values are associated with CORESETs having coresetpolindex values of 0 or CORESETs not configured with the coresetpolindex of parameter coresetpolindex, 2n-1 (n=1, 2, …) capability values or 2n+1 (n=0, 1,2, …) capability values are associated with CORESETs having coresetpolindex values of 1.

d. It is also possible to establish an association of the parameters coresetpoolndex and capability valuesFurther, an association of the parameter coresetpoolndex and the SRS resource set is established. For example:

d-1, reporting a capability value index by the terminal equipment

And under the condition that the terminal equipment reports one capability value index, the first relation is established between the one capability value index and a second designated CORESETPoolIndex value or all CORESETPoolIndex values, and the second relation is established between the one capability value index and a designated SRS resource set. The second specified coresetpoinlindex value may be 0 or 1.

d-2, reporting multiple capability value indexes by the terminal equipment

And under the condition that the terminal equipment reports a plurality of capability value indexes, establishing the first relation between part of capability value indexes in the plurality of capability values and a third appointed CORESETPoolIndex value, and establishing the first relation between the other part of capability value indexes and a fourth appointed CORESETPoolIndex value. The third specified coresetpoil index value may be 0 or 1 and the fourth specified coresetpoil index value may be 1 or 0.

Therefore, when the SRS resource set is determined, firstly, the CORESETPoolIndex value of the CORESET of the DCI or the PDCCH is determined, then the corresponding capability value is determined based on the CORESETPoolIndex value, and further the corresponding SRS resource set is determined based on the association relation between the capability value and the SRS resource set.

Further explanation of how the SRS resource set is determined based on the association relation determined by the capability value is provided below, for example:

for example, when the UE reports a capability value, the capability value is associated with CORESET having a coresetpoirindex value of 0;

when the UE reports 2 capability values, the first capability value is associated with the CORESET with the CORESETPoolindex value of 0, and the second capability value is associated with the CORESET with the CORESETPoolindex value of 1;

when the UE reports 3 or more capability values, the 2n_1 (n=1, 2, …) or 2n+1 (n=0, 1,2, …) capability values are associated with CORESET having CORESET value 0, and the 2n (n=0, 1,2, … or n=1, 2, …) capability values are associated with CORESET having CORESET value 1.

After detecting DCI with an SRI domain in a certain CORESET, the UE may determine a CORESET-associated capability value according to the predefined rule, further determine a maximum SRS port and an SRS resource set corresponding to the capability value, and determine corresponding SRS resources and PUSCH transmission ports according to the indication of the SRI.

It should be noted that the above-mentioned association is merely illustrative, and is not intended to limit the embodiments of the present application.

Example 4), predefined rules established based on TCI state configuration in specified parameters:

different TCI state configurations may be predefined to associate different SRS resource sets.

Thus, in determining SRS resource set for transmitting PUSCH, TCI status configuration associated with DCI may be determined first, and then according to the predefined rule, it may be determined which SRS resource set to use for determining SRS resource.

For example, the TCI status configuration may be status bits in the TCI field in the DCI. For example, one TCI field indicates N TCI states. The predefined rule may be that each TCI status bit corresponds to a set of SRS resources. For example, the TCI field indicates 4 TCI states, with a first TCI state bit and a second TCI state bit for a downstream TCI state indication, and a third TCI state bit and a fourth TCI state bit for an upstream TCI state indication. According to a predefined rule, the terminal may determine that a third TCI status bit is associated with the first SRS resource set and a fourth TCI status bit is associated with the second SRS resource set. When the TCI status bit indicates a first specific value (e.g., '111') or Reserved value ('Reserved'), then it is indicated that the TCI status bit is not to be used. When the TCI status bit indicates a second particular value (e.g., '000' to '110'), then it indicates that the TCI status bit indicates a particular TCI status. Therefore, the terminal can determine the SRS resource set acted by the DCI according to the indication of the TCI in the DCI and the association of the TCI state bit and the SRS resource set, and further determine that the corresponding SRS resource is used for PUSCH transmission.

For another example, it is still determined by predefined rules that one or more TCI status bits each correspond to a set of SRS resources. When the TCI field indicates a TCI state, the SRS resource set field or another information field is used to indicate which information bit is in effect, e.g., the first TCI state bit is in effect, or the second TCI state bit is in effect, or both 2 TCI state bits are in effect. If SRS resource set is used, for example, SRS resource set indicates '0' indicating that the first TCI state is in effect, 1' indicates that the second TCI state is in effect, and 2' or 3' indicates that both TCIs are in effect. Therefore, the terminal can determine the SRS resource set acted by the SRI domain in the current DCI according to the indication of the DCI and the predefined rule, and further determine that the corresponding SRS resource is used for PUSCH transmission.

Example 5), determining SRS resource sets based on the capability value index in the specified parameter:

different capability value indexes may be predefined to associate different SRS resource sets.

Thus, when determining the SRS resource set for transmitting PUSCH, the capability value reported by the terminal device may be determined first, and then according to the predefined rule, it may be determined which SRS resource set to use to determine the SRS resource.

For example, a first capability value index is associated with SRS resource set 0 and a second capability value index is associated with SRS resource set 1. Of course, the association relationship is merely illustrative, and is not intended to limit the embodiments of the present application. The first capability value index and the second capability value index are respectively ordered from small to large or from large to small according to the value of the SRS port. For example, the number of SRS ports corresponding to the capability value index reported by the terminal is 2 and 4, respectively, and the first capability value index refers to the capability value index with the number of SRS ports being 2, and the second capability value index refers to the capability value index with the number of SRS ports being 4.

For another example, the terminal reports the capability value index for each TRP (for example, corresponding to coresetpolindex value of 0 or 1) schedule, and both the network device and the terminal may determine the SRS resource set corresponding to the TRP (for example, corresponding to coresetpolindex value of 0 or 1) schedule.

Step 103, determining SRS resources based on the SRS resource set.

In implementation, SRS resources are determined based on the SRI field in the DCI.

Step 104, sending a PUSCH based on the SRS resource.

In summary, there may be various implementations based on the predefined rule, and the predefined rule may be determined to be adopted according to the actual requirement when implementing. When the terminal equipment adopts a predefined rule to determine the SRS resource set, the terminal equipment can track the SRS resource set, and can ensure that the SRS resource set determined by the terminal equipment is accurate and the accurate transmission of the PUSCH can be ensured.

As shown in fig. 2, a flowchart of a method for determining SRS resource set for a terminal device based on predefined rules, the method being applied to a scenario in which PUSCH is transmitted through at least one CG configuration, comprising the following steps 201-204:

step 201, under the condition that the terminal equipment acquires SRI contained in CG configuration, determining an association relationship between a designated parameter and SRS resource set based on a predefined rule; and in step 202, a set of SRS resources is determined based on the association.

Wherein the predefined rule is used for determining the association relationship between the specified parameter and the SRS resource set; the specified parameters include at least one of: the higher layer parameters coresetpoolndex, transmission configuration indication TCI status configuration, capability value index of the terminal device, SRS resource set index, CG index, specified radio resource control RRC parameters.

The specified parameters may be configured by RRC parameters, e.g., the RRC parameters may be configured under RRC-configurable uplink, or srs-resource eindicator srs-resource eindicator2-r 17. The CG configuration contains an SRI indication, which may be configured by SRS-resource indicator or SRS-resource indicator2-r17, indicating the SRS resource in the SRS resource set associated therewith. The CG index may be a CG configuration ID, such as configurable grantconfildindex-r 16 (up to 32).

In some embodiments, when the specified parameter includes a higher-level parameter coresetpoolndex, determining the SRS resource set based on the association relationship may be implemented as:

acquiring the CG configuration or the CORESETPoolIndex associated with the SRI; and selecting an SRS resource set which is configured in the higher-layer parameters of the SRS resource set and is the same as the CORESETPoolIndex configured by the CG or associated with the SRI from at least one SRS resource set as the SRS resource set for transmitting the PUSCH.

Wherein the coreepoolindex value associated therewith may be configured under one CG configuration or one SRI indication, and the SRS resource set is also associated with one coreepoolindex value, so that the CG configuration or SRI indication associated with the same coreepoolindex value is associated with the SRS resource set. If a CG configuration includes an SRI indicator (SRS-resource indicator or SRS-resource indicator2-r 17), the SRS resource set corresponding to the value of the coreetpolindex associated with the CG configuration is the SRS resource set associated with the SRI indicator; if a CG includes multiple SRI indications, each SRI indication may be associated with a different coreetpoolndex value, i.e., a different SRS resource set, respectively.

In some embodiments, when the specified parameter includes an SRS resource set index, determining an SRS resource set based on the association relationship may be implemented as: and taking the SRS resource set corresponding to the CG configuration or the SRI associated SRS resource set index as the SRS resource set for transmitting the PUSCH.

Wherein an SRS resource set index associated therewith may be configured under one CG configuration or one SRI indication, which SRS resource set index may correspond to the higher layer parameter SRS-ResourceSetId. If one CG configuration comprises one SRI indication, the SRS resource set corresponding to the SRS resource set index associated with the CG configuration is the SRS resource set associated with the SRI indication; if one CG includes multiple SRI indications, each SRI indication may be associated with a different SRS resource set index, i.e. with a different SRS resource set, respectively.

In some embodiments, when the specified parameter includes a capability value index of the terminal device, determining the SRS resource set based on the association relationship may be implemented as: and determining an SRS resource set corresponding to the CG configuration or the capability value index of the terminal equipment associated with the SRI as the SRS resource set for transmitting the PUSCH.

Wherein the capability value index of the terminal device associated with it can be configured under one CG configuration or one SRI indication, and the SRS resource set is also associated with one capability value index, so that the CG configuration or SRI indication and the SRS resource set associated with the same capability value index are associated. If one CG configuration comprises one SRI indication, SRS resource set corresponding to the associated capability value index of the CG configuration is the SRS resource set associated with the SRI indication; if one CG includes multiple SRI indications, each SRI indication may be associated with a different capability value index, i.e. a different SRS resource set, respectively.

In some embodiments, when the indication parameter includes TCI state configuration, determining the SRS resource set based on the association relationship may be implemented as: determining the CG configuration or the SRI associated TCI state configuration; and determining the SRS resource set associated with the TCI state configuration as the SRS resource set for transmitting the PUSCH.

Wherein, what number of TCI states are associated can be configured under one CG configuration or one SRI indication, and the SRS resource set is also associated with one TCI state (such as a first TCI state configured or indicated, or a second TCI state, etc.), so that the CG configuration or SRI indication and the SRS resource set associated with the same TCI state are associated. If one CG configuration comprises one SRI indication, SRS resource set corresponding to the TCI state associated with the CG configuration is the SRS resource set associated with the SRI indication; if a CG includes multiple SRI indications, each SRI indication may be associated with a different TCI state, i.e., with a different SRS resource set, respectively.

In some embodiments, when the specified parameter includes a CG index, the association may include: and the association relation between the CG index configured in the CG configuration and the SRS resource set.

The CG index configured in the CG configuration may be understood as specifying RRC parameters.

In a possible implementation manner, the association relationship between the CG index configured in the CG configuration and the SRS resource set includes: the odd CG index corresponds to one SRS resource set of the two SRS resource sets configured by the network device, and the even CG index corresponds to the other SRS resource set.

In this embodiment, CG indexes (configurable grantconfiguginex-r 16) have a predefined correspondence with SRS resource set indexes, odd CG indexes corresponding to the first SRS resource set and even CG indexes corresponding to the second SRS resource set. The corresponding SRS resource set may be determined according to the CG index configured in the CG configuration.

In some embodiments, when the specified parameter includes a specified RRC parameter, the association relationship may include: and the association relation between the designated RRC parameter and the SRS resource set configured in the CG configuration.

In a possible implementation manner, the CG configuration includes a second CG index of another CG associated with the CG configuration, and the association between the designated RRC parameter and the SRS resource set configured in the CG configuration includes the following two cases:

in the first case, if the first CG index corresponding to the CG configuration is smaller than the second CG index, the first CG index corresponds to a first SRS resource set of the two SRS resource sets configured by the network device.

In the second case, if the first CG index corresponding to the CG configuration is greater than the second CG index, the first CG index corresponds to a second SRS resource set of the two SRS resource sets configured by the network device.

The second CG index of the other CG associated in the CG configuration may be understood as a specified RRC parameter, or the first CG index and the second CG index may be both understood as specified RRC parameters, respectively associated with two SRS resource sets.

In addition, when the CG configuration does not include association information with other CGs, that is, the CG corresponding to the CG configuration does not associate with other CGs, the association relationship includes: the CG configures one SRS resource set, e.g., a first SRS resource set, of a plurality of SRS resource sets configured for the corresponding network device.

In this embodiment, the network device may pre-establish an association between 2 CGs, for example, the network device configuration part CG may make simultaneous transmission (or repeated transmission) in combination, for example, including an ID of the CG in the CG configuration, and a CG ID for simultaneous transmission or repeated transmission in combination with the CG, such as the following configuration codes:

ConfiguredGrantConfig::＝SEQUENCE{

…

configuredGrantConfigIndex-r16

ConfiguredGrantConfigIndex-r16

OPTIONAL,--Cond CG-List

associatedconfiguredGrantConfigIndex

ConfiguredGrantConfigIndex-r16

…

}

wherein associable configurable grantconfiguginex is used to configure CG indexes of other associated CGs.

For example, among 2 CG associated with other CG, CG having a lower CG index may be associated with a first SRS resource set, and CG having a higher CG index may be associated with a second SRS resource set. CG that is not associated with other CG may be associated with only the first SRS resource set.

In another possible implementation manner, the association relationship between the designated RRC parameter configured in the CG configuration and the SRS resource set includes:

For example, a first RRC parameter corresponds to a first SRI indication (SRS-Resourceindicator) that corresponds to a first SRS resource set, and a second RRC parameter corresponds to a second SRI indication (SRS-Resourceindicator 2-r 17) that corresponds to a second SRS resource set. The network device may configure only srs-resourceidosator or srs-resourceidosator 2-r17 in CG configuration, or both srs-resourceidosator and srs-resourceidosator 2-r17.

Step 203, determining SRS resources based on the SRS resource set.

In implementation, SRS resources are determined based on the SRI in the CG configuration. The SRI indication (SRS-ResourceBinder or SRS-ResourceBinder 2-r 17) indicates the SRS resource in the SRS resource set associated therewith.

Step 204, sending PUSCH based on the SRS resource.

In summary, there may be various implementations based on the predefined rule, and the predefined rule may be determined to be adopted according to the actual requirement when implementing.

In the embodiment of the present application, the method for determining SRS resource set for the terminal device based on the predefined rule may also be applied to a scenario where DCI scheduling PUSCH and CG configuration transmission PUSCH are performed simultaneously, and in this scenario, for DCI scheduling PUSCH, SRS resource set may be determined by the method shown in fig. 1 in the foregoing embodiment; for CG configured PUSCH transmission, the SRS resource set may be determined by the method shown in fig. 2 in the foregoing embodiments, which is not described herein.

The terminal device may select 2 CGs for simultaneous transmission or repeated transmission, and at this time, may select CGs associated with different SRS resource sets for transmission. The terminal device may also select 1 CG to transmit simultaneously or repeatedly with the DCI schedule, where the selected CG and DCI schedule are associated with different SRS resource sets, respectively. The terminal device may also select 2 or more CGs associated for simultaneous or repeated transmission.

2. Determining SRS resource set based on indication information of network device

As shown in fig. 3, a flowchart of a method for determining SRS resource set for indication information of a terminal device network device, where the method is applied to a scenario where at least one DCI schedules a physical PUSCH or a scenario where PUSCH is transmitted through at least one CG configuration, and may also be applied to a scenario where DCI schedules a PUSCH and CG configuration transmit PUSCH simultaneously, where the steps include:

Step 301, a network device configures indication information for indicating a channel sounding reference signal SRS resource set for the terminal device;

and step 302, the network equipment sends the indication information to the terminal equipment.

In step 303, if the terminal device detects or acquires the SRI contained in the CG configuration in the DCI, the association between the specified parameter and the SRS resource set of the channel sounding reference signal is determined based on the indication information of the network device.

Step 304, the terminal device determines the SRS resource set according to the association relation.

The indication information of the network equipment is used for determining the association relation between the designated parameter and the SRS resource set; the specified parameters include at least one of: coreetpolindex, CORESET detected for transmission of the DCI or PDCCH, TCI status configuration, specified information field in the DCI, capability value index of the terminal device, SRS resource set index, CG index, specified radio resource control RRC parameter.

Therefore, when the SRS resource set is determined, the SRS resource set is determined according to specific parameters in the indication information of the network side, and the SRS resource set can be accurately understood based on the indication of the network side.

In implementation, the indication information of the network device includes at least one of:

1) Coresetpoolndex configured in the higher layer parameters of SRS resource set; in this way, the SRS resource set indicated by the indication information can be obtained by the higher layer parameter of the SRS resource set.

When the indication information is coresetpoolndex configured in a higher-level parameter of the SRS resource set, the association relationship may be understood as an association relationship of coresetpoolndex and the SRS resource set.

In this case, when the terminal device detects the SRI in the DCI, determining the SRS resource set may be implemented as:

detecting CORESET for transmitting the DCI or PDCCH;

obtaining a coresetpoillolndex of the CORESET;

In another case, when the terminal device acquires the SRI contained in the CG configuration, determining the SRS resource set may be implemented as:

acquiring the CG configuration or the CORESETPoolIndex associated with the SRI;

For example, the following example illustrates the configuration of coreetpolindex parameters in SRS resource set-related higher layer parameters:

in this example, the higher-layer parameter corresponding to the SRS resource set is SRS-ResourceSet, which is configured in the parameters SRS-ResourceSetToAddModList or SRS-ResourceSetToAddModListDCI-0-2, and the use (use) of the SRS resource set is configured as 'codebook' or 'non-Codebook'. Parameters SRS-ResourceSetToAddModList or SRS-ResourceSetToAddModListDCI-0-2 correspond to DCI formats 0_1 or 0_2, respectively, and 2 or more SRS resource sets with usages of 'codebook' or 'non-codebook' can be configured. The SRI is a 'SRS resource indicator' domain or a 'Second SRS resource indicator' domain, and can be carried by DCI format 0_1 or 0_2, where no SRI exists in DCI format 0_0.

An alternative implementation is to configure the associated coreetpolindex parameters under the higher-layer parameters SRS-resource set corresponding to SRS resource set. For example, the associated coretpoolindex parameter is configured only under the SRS-resource set corresponding to the SRS resource set with the use of 'codebook' or 'non-codebook', and the condition for the coretpoolindex parameter configuration under the SRS-resource set is that the use is 'codebook' or 'non-codebook'. For SRS resource set with usage of 'codebook' or 'non-codebook', the value of coresetpolindex can be considered to be 0 if the coresetpolindex is not configured. When the PUSCH transmission mode related parameter txConfig is configured as 'codebook' or 'non-codebook', and the DCI is detected in CORESET with a value of k (k=0 or 1) of CORESET polindex, the terminal may determine that the SRS resource set associated with SRI is the SRS resource set with a value of k of CORESET polindex, and the user is also the SRS resource set of 'codebook' or 'non-codebook'. This method is applicable to the case where one or more SRS resource sets with user's name ' code book ' or ' non-code book ' are configured in the higher-layer parameters SRS-ResourceSetToAddModList or SRS-ResourceSetToAddModListDCI-0-2. The terminal expects that the number of SRS resource sets with k values of use 'codebook' or 'non-codebook' in one BWP or one cell is not more than 1, or that the number of SRS resource sets with k values of use 'codebook' or 'non-codebook' configured in the higher-layer parameter SRS-resourcestto addmodlist or SRS-resourcestto addmodlist dci-0-2 is not more than one. If the higher-level parameters SRS-ResourceStokeToAddModList or SRS-ResourceToAddModList DCI-0-2 are configured with more than 1 SRS resource set with a value k of CORESPOOL index of 'codebook' or 'non-codebook', the SRI-associated SRS resource set in the DCI can be determined jointly using this method and other methods described below.

In addition, a parameter coreetpolindex may be configured in an SRS resource set whose usage is 'beam management' or 'antenna switching', to indicate association between the SRS resource set and CORESET (TRP), so as to be used for uplink beam management or uplink antenna switching, so as to facilitate subsequent multi-panel transmission.

In the embodiment, unless otherwise specified, the SRS resource set refers to the SRS resource set whose use is 'codebook' or 'non-codebook'.

2) If the indication information is the capability value index of the terminal equipment configured by CORESET; thus, by configuring the capability value index of the terminal device under CORESET, the SRS resource set can be determined according to the capability value index.

When the terminal device detects the SRI in the DCI, determining the SRS resource set may be implemented as:

detecting CORESET for transmitting the DCI or PDCCH;

For example, a parameter Capability [ Set ] Index is configured under each CORESET, and the UE determines a corresponding SRS resource Set according to the number of SRS ports corresponding to the Capability [ Set ] Index (corresponding to the 3 rd case in the second mode).

A panel-related Capability value (e.g., capability Set Index) is configured below each CORESET, indicating that the CORESET may schedule a certain panel of the UE for transmission. If the number of SRS ports included in SRS resource set of SRS-ResourceSetToAddModList or SRS-resourcesettoaddmodlistdi-0-2 is different, for example, the number of SRS ports included in SRS resource set 5 (SRS-resourcesetid=5) is 2,SRS resource set 2 (SRS-resourcesetid=2) is 4, the capability value 1 corresponds to SRS maximum port number of 4, the capability value 2 corresponds to SRS maximum port number of 4, and after the UE detects DCI with SRI in a certain CORESET, the capability value (e.g. capability value 2) associated with SRI can be determined according to the association relationship, and further the associated SRS port number (4 ports) can be determined, so that the SRS resource set (i.e. SRS resource set 2) associated with SRI can be indirectly determined.

CORESETs with the same coresetpolindex value may correspond to the same capability value, or UEs expect CORESETs with the same coresetpolindex parameter to have the same capability value, so that a fixed association of TRPs and panels may be established, indicating that one TRP schedules only panels with one capability value. The CORESETs with different coresetpolindex values can correspond to different capability values, so that different panels of a plurality of TRP scheduling can be ensured, no conflict is caused, that is, the same panel of the same scheduling of a plurality of TRPs at the same time can not occur, and the condition that the scheduling of a network side exceeds the capability of a terminal is avoided.

3) The indication information includes a designated information field in the DCI.

In some possible embodiments, the specified information field in the DCI may include at least one of:

a first information indication field for indicating the SRS resource set;

third information indicating a status of the TCI indicates a domain.

For example, the first information indication field may identify an identification of SRS resource set, whereby the SRS resource set may be determined based on the first information indication field.

For another example, the capability value index of the terminal device is determined based on the second information indication field, and then the SRS resource set to be employed may be determined based on an association relationship between the capability value index and the SRS resource set established in advance.

For another example, the third information indication field may determine a TCI state indicated by the network device, and then pre-establish SRS resource sets associated with different TCI states, thereby determining the SRS resource set to be employed based on the TCI state in the DCI.

For another example, for the case where different indication fields are used in combination, one possible embodiment indicates 2 TCI states for the TCI field in the DCI, then uses the SRS resource set field or other information field to specify that one of the TCI state bits is used (i.e., single TRP transmission), then only one of the 2 TCI states indicated by the TCI state field will be valid. The SRS resource set associated with the validated TCI state is determined based on a preset rule for PUSCH transmission.

The terminal device determining the SRS resource set may be implemented as: acquiring the designated information field in the DCI; then, the SRS resource set indicated by the specified information domain is used as the SRS resource set for transmitting the PUSCH.

In addition, since 2 TRPs are independently scheduled, each of which is independently indicated by SRS resource set or capability value, the 2 DCIs may indicate the same SRS resource set and further indicate the same SRS resource, and thus PUSCH scheduled by 2 TRPs may use the same port as SRS port to transmit PUSCH, which may exceed the capability of UE. For example, each of 2 TRP indicates that the terminal uses a 4-port panel or uses 4 ports to transmit PUSCH with 4 data streams, whereas a panel with only one 4 ports for the UE cannot transmit a total of 8 data streams. However, for some UEs, the number of panels is large, and the number of txrus is also large, and even if 2 TRP scheduled UEs use the same SRS resource set or SRS resource as the transmission port of PUSCH, the UEs can transmit according to the scheduling of the network side. Therefore, the UE may previously transmit capability information of whether to support a designated information field in the DCI to the network device. If the UE has no correlation capability, the network device cannot use the method for the UE.

After the terminal determines the SRS resource set associated with the DCI, determining that the corresponding SRS resource is used for PUSCH transmission according to the indication of the SRI. For PUSCH transmission based on codebook, the DCI also includes a TPMI field for instructing the terminal to send a precoding codeword and a corresponding layer number (layer). If the terminal capability is low, it may happen that the number of PUSCH ports scheduled by 2 DCIs is greater than the maximum number of ports that the terminal can transmit, or the number of data layers scheduled by 2 DCIs exceeds the maximum number of data layers that the terminal can transmit. To avoid this, the scheduling of DCI may also be limited, such as limiting the maximum number of ports of PUSCH scheduled per DCI, or limiting the maximum number of data layers scheduled per DCI. For example, the terminal supports 4 data layer transmissions at most, and it may be limited that the number of data layers of each DCI schedule is not more than 2, or the number of PUSCH data layers of DCI schedules transmitted in a coreset with a value of 0 or without coreepoolindex is not more than 3, the number of PUSCH data layers of DCI schedules transmitted in a coreset with a value of 1 is not more than 1, etc. Or, when the sum of the data layers of the 2 DCI schedules is greater than the maximum layer number (such as Nmax) supported by the terminal, the PUSCH scheduled by the designated DCI is reduced to an Nmax-N1 layer, wherein N1 is the data layer scheduled by another DCI. For example, the number of PUSCH data layers scheduled by DCI transmitted in corerset with or without coreepoolindex value of 0 is transmitted according to TPMI indicated by DCI, and the number of PUSCH data layers scheduled by DCI transmitted in corerset with coreepoolindex value of 1 is reduced to Nmax-N1. After the data is reduced, the network device may be notified of the data stream reduction event, e.g., the reduced data stream, by UCI feedback or other uplink signaling, etc. The precoding codeword corresponding to the current data stream may be additionally indicated, and the precoding codeword may also be a codeword predefined in the protocol. For example, a default precoding codeword is defined for PUSCH transmissions of rank 1,2,3,4, respectively, for use in data stream puncturing.

The following describes how the three specified information fields respectively determine SRS resource sets:

(1) Based on the first specified information field:

for example, the indication of the corresponding SRS resource set by the first specified information domain, i.e. the SRS resource set domain, may be implemented as:

when 2 SRS resource sets are configured (the use is 'codebook' or 'noncodebook'), the SRS resource set field bit width is 1bit, and only the first SRS resource set or the second SRS resource set is indicated.

In implementation, the relationship between the index of the bit field and the indicated SRS resource set may be as shown in table 2:

TABLE 2

Bit field mapping to index	SRS resource set indication
		0	SRI and TPMI domains and first SRS resource set association
1	SRI and TPMI domains and second SRS resource set association

When 3 SRS resource sets are configured, the SRS resource set field bit width is 2 bits, and the SRS resource set is indicated by using table 3. The relationship is shown in Table 3:

TABLE 3 Table 3

Similarly, when 4 SRS resource sets are configured, the SRS resource set field bit width is 2 bits, and the SRS resource set indication is performed using table 4.

TABLE 4 Table 4

Based on the above cases of the tables, after receiving the SRI, the UE determines the SRS resource set associated with the SRI according to the SRS resource set indication domain, determines the corresponding SRS resource according to the indication of the SRI, and uses the same antenna port as the SRS resource to transmit the PUSCH.

(2) Based on the second specified information field:

for example, the second designated information field is used to indicate the capability value, and the UE determines the corresponding SRS resource set according to the maximum SRS port number associated with the capability value (the second information designated field in case 4 of the corresponding mode 2).

When the UE reports 1 capability value, the bit width of the capability value indication field (i.e. the second information indication field) is 0 bit, the UE expects that the number of SRS resources set with user being 'codebook' or 'noncodebook' configured at the network side is 1, and the SRI in the DCI is associated with the SRS resources set, i.e. indicates the SRS resources in the SRS resources set.

When the UE reports 2 capability values, the capability value indicates that the field bit width is 1 bit, and the code points '0' and '1' correspond to the first capability value and the second capability value, respectively.

When the UE reports 3 capability values, the capability value indicates that the domain bit width is 2 bits, and the code points '00, 01' and '10' correspond to the first, second and third capability values respectively, and the code point '11' is in a reserved state.

When the UE reports 4 capability values, the capability value indicates that the field bit width is 2 bits, and the code points '00, 01', '10' and '11' correspond to the first, second, third and fourth capability values, respectively.

The UE may determine a corresponding maximum number of SRS ports according to the capability value indicated in the DCI, and further determine a corresponding SRS resource set according to the maximum number of SRS ports. In this way, the panel of the individual TRP schedules can be dynamically changed.

The second information indication field may be a new information field, or may use an existing DCI information field, such as a TCI indication field, an SRS resource set indication field, etc.

Since 2 TRPs are independently scheduled, and each is independently indicated by an SRS resource set or a capability value, the 2 DCIs may indicate the same SRS resource set and further indicate the same SRS resource, and thus PUSCH scheduled by 2 TRPs may be transmitted by using the same port as the SRS port, which may possibly exceed the capability of the UE. For example, each of 2 TRP indicates that the terminal uses a 4-port panel or uses 4 ports to transmit PUSCH with 4 data streams, whereas a panel with only one 4 ports for the UE cannot transmit a total of 8 data streams. However, for some UEs, the number of panels is large, and the number of txrus is also large, and even if 2 TRP scheduled UEs use the same SRS resource set or SRS resource as the transmission port of PUSCH, the UEs can transmit according to the scheduling of the network side. Therefore, the UE may report in advance whether the capability of dynamically indicating SRS resource set-related information is supported. If the UE has no relevant capability, the network side cannot use the method for the UE.

A certain limitation may also be made on the scheduling, for example, in the case that 2 PUSCH transmission schemes for DCI scheduling are different, for example, one PUSCH transmission based on codebook, another PUSCH transmission based on codebook, and non-codebook based PUSCH transmission, SRS resource set under two usages are not conflicting. In this case, the network side configures 2 txConfig parameters, such as txConfig and txConfig-r18, for the UE, corresponding to the cases where coresetpoolndex takes values of 0 and 1, respectively.

(3) Indicating a domain based on the third information:

for example, the TCI field in the DCI indicates a TCI state, and the UE determines a corresponding SRS resource set according to the TCI state. Similar to the method based on the second information indication field, the TCI field in the DCI may be detected, then the TCI state indicated by the TCI field is obtained, and then the SRS resource set used is determined according to the association relationship between the pre-defined TCI state and the SRS resource set.

4) The indication information indicates TCI state configuration for transmission configuration; thus, the SRS resource set can be implicitly indicated by TCI state configuration.

In one case, when the terminal device detects the SRI in the DCI, determining the SRS resource set may be implemented as:

determining a TCI status configuration associated with the DCI;

In the embodiment of the present application, the TCI status configuration associated with the DCI includes at least one of the following:

at least one TCI state activated by MAC-CE signaling; for example, multiple sets of TCI state combinations are activated using MAC-CE signaling, and then one set of TCI state combinations is indicated using DCI signaling. Each set of TCI state combinations may include an uplink TCI state and/or a downlink TCI state, where the uplink TCI state and the downlink TCI state may be one or more, in the case of multiple, corresponding to multiple channels or information (e.g., corresponding to multiple TRP or multiple panel transmissions), respectively. When the MAC-CE signaling activates the TCI state, the SRS resource set index may be carried, indicating that the TCI state may act on the corresponding SRS resource set transmission. The network side may activate a corresponding TCI state for each configured SRS resource set, respectively, e.g. all TCI state combinations in MAC-CE signaling are associated with one SRS resource set. The SRS resource set index carried in the MAC-CE signaling may be an absolute index or a relative index of the SRS resource set. In addition, the MAC-CE signaling carries a coresetpoolndex value, so that an association between DCI and TCI state activated MAC-CE signaling is established. Specifically, after detecting DCI, the terminal determines a corresponding MAC-CE signaling according to the CORESET where the DCI is located or a parameter coresetpoolndex of the CORESET, thereby determining an associated SRS resource set. As another example, each TCI state combination in MAC-CE signaling is associated with one SRS resource set, in which case the terminal may determine the corresponding associated SRS resource set from the TCI state combination (i.e., the code point of the TCI state, e.g., '011') indicated in the DCI signaling.

At least one TCI state currently in effect (which may be understood to be in effect);

In another case, when the terminal device acquires the SRI included in the CG configuration, determining the SRS resource set may be implemented as:

determining the CG configuration or the SRI associated TCI state configuration;

Wherein, what number of TCI states (e.g., a first TCI state configured or indicated, or a second TCI state, etc.) are configurable under one CG configuration or one SRI indication, the SRS resource set is also associated with one TCI state, and thus, the CG configuration or SRI indication and the SRS resource set associated with the same TCI state are associated. If one CG configuration comprises one SRI indication, SRS resource set corresponding to the TCI state associated with the CG configuration is the SRS resource set associated with the SRI indication; if a CG includes multiple SRI indications, each SRI indication may be associated with a different TCI state, i.e., with a different SRS resource set, respectively.

Index of one SRS resource set associated with TCI state configured by RRC signaling;

index of SRS resource set contained in the TCI status signaling activated by MAC CE.

For example, the configuration at the network side is different from the association of the TCI state configuration with the SRS resource set, and the UE determines the (associated) SRS resource set acted by the SRI through the TCI state configuration.

In a possible implementation, when the RRC configures the TCI states, each TCI state is associated with an index of an SRS resource set.

In another possible implementation, the SRS resource set index is included when the MAC CE activates the TCI state (similar to the COREETPoolIndex parameter carried in Rel-16 TCI activation/update MAC CE).

In one possible implementation, assuming that (integrated) TCI status indications are used, each TCI status bit corresponds to one SRS resource set (predefined rule), when one TCI status bit in one DCI schedules one SRS resource set, the indication of the other TCI status bit is a specific value, e.g. "111", corresponding to a reserved bit, and the terminal determines the SRS resource set to which the SRI acts according to the TCI status indication.

In one possible implementation, each TCI state indication bit corresponds to a set of SRS resources, and when the TCI state bit indicates a first specific value (e.g., '111') or a Reserved value ('Reserved'), it indicates that the TCI state bit is not used. When the TCI status bit indicates a second particular value (e.g., '000' to '110'), then it indicates that the TCI status bit indicates a particular TCI status. Therefore, the terminal can determine the SRS resource set acted by the DCI according to the indication of the TCI in the DCI and the association of the TCI state bit and the SRS resource set, and further determine that the corresponding SRS resource is used for PUSCH transmission.

In addition to using the specified information field in the DCI based on the above method, in the embodiment of the present application, the network device may instruct the terminal device to use the SRS resource set index, and the terminal device may determine the SRS resource set according to the DCI and the resource set index.

In a possible implementation, the SRS resource set index indicated by the network device includes an SRS resource set index configured for CORESET. At this time, the terminal device may detect CORESET for transmitting the DCI or PDCCH; and taking the SRS resource set corresponding to the SRS resource set index of the CORESET as the SRS resource set for transmitting the PUSCH.

For example, an associated SRS resource set index is configured under each CORESET, which may be associated with SRS resource sets having usages of codebook and/or non-codebook. The associated SRS resource set index may be configured within a higher-level parameter, controlresource set, corresponding to CORESET. The SRS resource set index may be a higher layer parameter SRS-ResourceSetId, i.e. an absolute index of SRS resource set (e.g. 0-15, ordered within one BWP). But also the relative index of SRS resource set. For example, the relative index is a first SRS resource set or a second SRS resource set, and these two indexes respectively correspond to the SRS resource set with a lower index or a higher index in the SRS resource set of the 'codebook' or the 'non-codebook', which is configured in SRS-ResourceSetToAddModList or SRS-resourcesettoaddmodlistdi dci-0-2.

After detecting the DCI with the SRI, the terminal equipment can determine SRS resource set associated with the SRI according to the CORESET where the DCI is located, and further determine corresponding SRS resources. The SRS resource set indexes associated with CORESET with the same coreetpolindex parameter may be the same or different, and if the SRS resource set indexes are the same, it means that one TRP is associated with one SRS resource set, i.e. the TRP only schedules the SRS resource set for transmission.

In the application, the network device can configure two PUSCH transmission parameters (such as txconfig and txconfig_r18) for the terminal device, and the values of the two PUSCH transmission parameters are the same or different.
