Description

Technical Field

[0001] Embodiments of the present disclosure relate to wireless communication technologies, and more particularly, to methods and apparatuses for physical uplink shared channel (PUSCH) transmission, such as configured grant (CG) type 1 PUSCH transmission.

Background Art

[0002] According to current protocols, whether CG type 1 PUSCH transmission is sent to a single transceiver point (TRP) or to two TRPs is determined by the number of configured power control parameter sets in the corresponding configuration. However, in a common beam framework, since the power control parameter set is determined according to the common beam indicated for uplink (UL) transmission, it is not configured in the corresponding configuration of CG type 1 PUSCH. In this case, it is necessary to solve how to determine which common beam is applicable to CG type 1 PUSCH transmission, and whether CG type 1 PUSCH transmission is sent to a single TRP or multiple TRPs.

[0036] Referring to FIG. 1, the wireless communication system 100 may include a BS 101, a TRP 103 (e.g., TRP 103a and TRP 103b), and a UE 105 (e.g., UE 105a, UE 105b, and UE 105c). For simplicity, only one BS 101, two TRPs 103, and three UEs 105 are shown, but it should be noted that the wireless communication system 100 may include more or fewer communication devices, apparatuses, or nodes according to some other embodiments of the present application.

The UE 101 may communicate with the BS 102 via an uplink (UL) communication signal.

[0038] In some embodiments of the present application, BS101 may be referred to as an access point, access terminal, base, base unit, microcell, Node-B, evolved Node B (eNB), gNB, or ng-eNB, Home Node-B, relay node, or device, or may be described using other terms used in the art. UE105 (e.g., UE105a, UE105b, and UE105c) may include, for example, but not limited to, computing devices, wearable devices, mobile devices, internet of things (IoT) devices, vehicles, etc.

[0040] Regarding PUSCH transmission, and in particular, CG type 1 PUSCH transmission, there are some conventions for multi-transmission and reception point (M-TRP) CG type 1 PUSCH in R17, which are shown below. ·For type 1 CG-based m-TRP PUSCH repetitions, introduce the second fields of "pathlossReferenceIndex", "srs-ResourceIndicator", and "precodingAndNumberOfLayers" into "rrc-ConfiguredUplinkGrant". ·When the DCI schedules a retransmission of a CG-PUSCH for type 1 CG-PUSCH or type 2 CG-PUSCH (DCI with CRC scrambled with CS-RNTI and NDI = 1), while the CG configuration is RRC-configured using two fields of power control parameters, apply the same procedure as for DCI activation for the previously agreed type 2 CG, i.e., - The first (legacy) RRC configuration fields "p0-PUSCH-Alpha" and "powerControlLoopToUse" are associated with the first SRS resource set. - The second (new) RRC configuration fields "p0-PUSCH-Alpha" and "powerControlLoopToUse" are associated with the second SRS resource set. - Applying the first RRC configuration field "p0-PUSCH-Alpha", the second RRC configuration field "powerControlLoopToUse", or both of them is determined from the new DCI field (for dynamic switching) of the activating DCI, similar to the case of DG-PUSCH. ·When the fallback DCI (DCI format 0_0) activates type 2 CG, or schedules a retransmission of type 1 CG or type 2 CG, and the CG configuration is RRC-configured using two sets of power control parameters (two "p0-PUSCH-Alpha" and "powerControlLoopToUse"): - The UE uses the first set of values for power control (the first RRC configuration "p0-PUSCH-Alpha" and "powerControlLoopToUse"). DCI containing a new 2-bit DCI field for dynamic switching activates type 2 CG or schedules a retransmission of type 1 CG or type 2 CG when the CG configuration is RRC-configured using only one set of power control parameters (one "p0-PUSCH-Alpha" and "powerControlLoopToUse"): - The UE shall expect that the new DCI field for dynamic switching is set to "00" and that all PUSCH repetitions are associated with the first SRS resource set. · For a BWP configured using two SRS resource sets for CB or NCB-based mTRP PUSCH repetitions with a type 1 CG configuration - If the CG is configured using only one field for each of "pathlossReferenceIndex", "srs-ResourceIndicator", "precodingAndNumberOfLayers", "p0-PUSCH-Alpha", and "powerControlLoopToUse", the PUSCH repetitions are associated with the first SRS resource set.

[0041] For M-TRP type 1 CG PUSCH, when two fields of "precodingAndNumberOfLayers" and / or "srs-ResourceIndicator" are present in "rrc-ConfiguredUplinkGrant" - The two precoding informations (for CB PUSCH) shown are determined separately using the two fields of "precodingAndNumberOfLayers". - The SRI shown (for CB / NCB PUSCH) is determined separately using the two fields of "srs-ResourceIndicator". · For mTRP type 1 CG PUSCH, when both srs-ResourceSetToAddModList and srs-ResourceSetToAddModListDCI-0-2 are configured with two SRS resource sets, the two SRS resource sets configured by srs-ResourceSetToAddModList are used to determine the SRS resource indication by the two srs-ResourceIndicator fields of mTRP CG PUSCH. · For type 1 CG-based multi-TRP PUSCH repetition: - The first (legacy) RRC configuration fields "p0-PUSCH-Alpha" and "powerControlLoopToUse" are associated with the first SRS resource set. - The second (new) RRC configuration fields "p0-PUSCH-Alpha" and "powerControlLoopToUse" are associated with the second SRS resource set. · For M-TRP CG type 1 PUSCH, - When two SRS resource sets with the usage set to "codebook" or "non-codebook" are configured in srs-ResourceSetToAddModList, those two SRS resource sets are used to determine the SRS resource indication by srs-ResourceIndicator and srs-ResourceIndicator2, - Otherwise, the two SRS resource sets with the usage set to "codebook" or "non-codebook" configured in srs-ResourceSetToAddModListDCI-0-2 are used to determine the SRS resource indication by srs-ResourceIndicator and srs-ResourceIndicator2.

[0042] For dynamic grant DG PUSCH or CG type 2 PUSCH, the SRS resource set indicator (SRI) field for indicating that the PUSCH is S-TRP PUSCH or M-TRP PUSCH is in the corresponding DCI. According to the above convention, whether the CG type 1 PUSCH is transmitted to a single TRP or two TRPs is determined by the number of configured power control parameter sets in the corresponding configuration. This is because when only one SRS resource is configured in each SRS resource set, there is no SRS resource indicator (i.e., srs-ResourceIndicator or srs-ResourceIndicator2).

[0043] However, the SRS resource set indicator field is not in the CG PUSCH configuration, and the CG type 1 PUSCH transmission is configured as an S-TRP or M-TRP according to the number of SRS resource indicators (i.e., srs-ResourceIndicator) and the number of power control parameter sets (e.g., p0-PUSCH-Alpha, pathlossReferenceIndex, and powerControlLoopToUse) configured in the configured grant PUSCH configuration.

[0044] In the common beam framework, the power control parameter set of the CG type 1 PUSCH is not configured in the CG PUSCH configuration and is determined according to the common beam indicated for UL transmission (e.g., PUSCH and PUCCH transmission).

[0045] However, considering that only one SRS resource is configured in any SRS resource set configured using the usage "codebook" or "non-codebook", there may be no srs-ResourceIndicator in the CG PUSCH configuration. In this case, when two common beams are indicated for UL transmission, it is not clear whether CG type 1 PUSCH transmission should be transmitted by one common beam (i.e., S-TRP PUSCH), or by two common beams (i.e., M-TRP PUSCH).

[0046] Therefore, it is necessary to solve how to determine whether PUSCH transmission, such as CG type 1, etc., is transmitted to a single TRP or multiple TRPs, especially when there is no SRS resource indicator (i.e., srs-ResourceIndicator) in the corresponding configuration. Embodiments of the present disclosure propose a technical solution for solving such technical problems, especially for CG type 1 PUSCH transmission (e.g., only PUSCH configured by RRC signaling).

[0047] Multiple SRS resource sets in a list, such as srs-ResourceSetToAddModList or srs-ResourceSetToAddModListDCI-0-2, whose usage in the list is set to "codebook" or "non-codebook", can be configured for M-TRP PUSCH transmission. The UE supports simultaneous transmission with multiple panels (i.e., STxMP), and multiple SRS resource sets in srs-ResourceSetToAddModList or srs-ResourceSetToAddModListDCI-0-2 whose usage is set to "codebook" or "non-codebook" may also be configured for STxMP PUSCH transmission, and the PUSCH transmission can be transmitted to one of the multiple TRPs or two or more of the multiple TRPs.

[0048] In the present disclosure, two SRS resource sets with their usage set to "codebook" or "non-codebook" may be configured for PUSCH transmission. The first SRS resource set among the two SRS resource sets may be the SRS resource set with a smaller index (or less identification information), and the second SRS resource set among the two SRS resource sets may be the SRS resource set with a higher index (or more identification information). For example, the first SRS resource set may have an index of "0", and the second SRS resource set may have an index of "1". In some other cases, more than two, for example, three SRS resource sets may be configured for codebook or non-codebook-based PUSCH transmission. The first SRS resource set among the three SRS resource sets may have the lowest index, the second SRS resource set among the three SRS resource sets may have an index higher than that of the first SRS resource set, and the third SRS resource set may have the highest index. For other numbers of SRS resource sets, they may be indexed in a similar manner.

[0049] In R17, for M-TRP PUSCH transmission, based on legacy beam indication (i.e., spatial relation information), the beam for PUSCH transmission is the same as the beam of the indicated SRS resource of the related SRS resource set. In the common beam framework, the beam for PUSCH transmission is indicated by downlink control information (DCI) format 1_1 or DCI format 1_2, and the medium access control control element (MAC CE) activates a plurality of transmission configuration indication (TCI) code points, or the MAC CE activates only one TCI code point that is not related to the beam of the related SRS resource. Moreover, each SRS resource set is configured by radio resource control (RRC) to follow the common beam indicated for uplink UL transmission. In R18, M-TRP PUSCH transmission is supported based on the common beam framework.

[0050] When two SRS resource sets configured for PUSCH transmission are configured to follow the indicated common beam, the beam of the SRS resource set related to the PUSCH transmission and the beam of the PUSCH transmission are the same, and the PUSCH and the related SRS resource set of the PUSCH are transmitted to the same TRP.

[0051] When two SRS resource sets configured for PUSCH transmission are not configured to follow the indicated common beam, the PUSCH transmission and the related SRS resource set of the PUSCH should also be transmitted to the same TRP. Each SRS resource of each SRS resource set is configured by RRC using a beam or activated by MAC CE using a beam when the two SRS resource sets are not configured to follow the indicated common beam. Considering that all SRS resources in one SRS resource set share the same power control parameter set, the beams of all SRS resources in one SRS resource set are associated with the same TRP. To ensure that the PUSCH transmission and its related SRS resource set are transmitted to the same TRP, an association is established between the beam and the TRP.

[0052] In the present disclosure, a TCI state group or a TCI state pool (hereinafter, "TCI state group" and "TCI state pool" may be used interchangeably as appropriate) can be used to identify a TRP. Therefore, two TCI state groups can be configured to identify two TRPs. Each beam is associated with one TCI state group by RRC signaling or a MAC CE indication. Therefore, when a PUSCH transmission is associated with a beam associated with a TCI state group, the beam of the associated SRS resource set of the PUSCH transmission is also associated with the TCI state group. On the BS side, it can configure or activate the beam for one of the two SRS resource sets configured for PUSCH transmission so as to be associated with one of the two TCI state groups, and configure or activate the beam for the other of the two SRS resource sets configured for PUSCH transmission so as to be associated with the other of the two TCI state groups. In the present disclosure, the beam may refer to a joint or UL TCI state.

[0053] Hereinafter, in the present disclosure, when a PUSCH transmission, such as a CG type 1 PUSCH transmission, etc., is configured to be associated with two common beams, the PUSCH transmission repetition of the PUSCH transmission associated with one common beam (which can be time-division multiplexed, frequency-division multiplexed, or single-frequency networked), the layer subset of the PUSCH transmission (e.g., SDM), or the frequency portion of the PUSCH transmission (e.g., frequency-division multiplexed) is referred to as a PUSCH transmission opportunity. According to the above, the PUSCH transmission opportunity associated with the common beam is also associated with the same SRS resource set of the two SRS resource sets.

[0054] Therefore, the common beam of the PUSCH transmission opportunity of PUSCH is always associated with the same TCI state group, and the beam of the associated SRS resource set of the PUSCH transmission opportunity is associated regardless of whether the two SRS resource sets configured for PUSCH transmission are configured to follow the common beam indicated for UL transmission.

[0055] According to some embodiments of the present application, an indicator field (e.g., called an SRS resource set indicator or a beam indicator) that may include 2 bits or other numbers of bits is introduced to indicate a common beam and an associated SRS resource set for, e.g., CG type 1 PUSCH, and may be provided in the corresponding configuration.

[0056] When only one SRS resource is configured for each of the two SRS resource sets configured for PUSCH transmission, the srs-ResourceIndicator field does not exist in the corresponding configuration for CG type 1 PUSCH transmission. In this case, the SRS resource set indicator or beam indicator is configured to indicate the beam of the PUSCH and the associated SRS resource set. When more than one SRS resource is configured for each SRS resource set, one or two srs-ResourceIndicator fields can be configured for, e.g., CG type 1 PUSCH transmission. In this case, the number of srs-ResourceIndicators can indicate whether the PUSCH transmission is sent to a single TRP or multiple TRPs. The SRS resource set indicator or beam indicator is not always required for, e.g., CG type 1 PUSCH transmission. Two scenarios are shown separately below. The first scenario is that the srs-ResourceIndicator does not exist for, e.g., CG type 1 PUSCH, and the SRS resource set indicator or beam indicator is always configured for, e.g., CG type 1 PUSCH transmission. The second scenario is that at least one srs-ResourceIndicator field exists for, e.g., CG type 1 PUSCH, and the SRS resource indicator or beam indicator can optionally be configured for, e.g., CG type 1 PUSCH transmission.

[0057] For example, FIG. 2 shows a method of PUSCH according to some embodiments of the present disclosure that can be performed by a BS.

[0058] In operation 201, the BS may transmit configuration information indicating CG type 1 PUSCH transmission. The configuration information includes at least one of: first indication information indicating the association of CG type 1 PUSCH transmission with at least a part of at least one common beam or the association of CG type 1 PUSCH transmission with at least a part of a plurality of SRS resource sets configured for CG type 1 PUSCH transmission; second indication information indicating the PUSCH format of CG type 1 PUSCH transmission; or third indication information including at most two SRS resource indicator values, and is included to indicate which common beam among at least one common beam applicable to uplink transmission in a slot is associated with CG type 1 PUSCH transmission. In operation 202, the BS may receive CG type 1 PUSCH transmission in a slot based on the configuration information.

[0059] Hereinafter, more specific embodiments are shown in various scenarios using CG type 1 PUSCH transmission as an example. The PUSCH transmission may be single-TRP PUSCH transmission or multi-TRP PUSCH transmission.

[0060] Scenario 1 In Scenario 1, in the configuration of PUSCH transmission, there is no SRS resource indication information (e.g., srs-ResourceIndicator), or the SRS resource indication information does not include an SRS resource indicator value, which means that only one SRS resource is configured for each SRS resource set for PUSCH transmission. The present disclosure proposes several strategies for determining one or more common beams for PUSCH transmission.

[0061] Strategy 1-1A In this solution, at least one common beam and a plurality of SRS resource sets are configured for PUSCH transmission, and the network may configure first indication information indicating the association of PUSCH transmission with at least a part of the plurality of SRS resource sets configured for PUSCH transmission. For example, the network may configure an SRS resource set indicator to indicate the associated SRS resource set for PUSCH transmission.

[0062] The indication information, that is, the SRS resource set indicator, may include 1 bit. Therefore, there are two states of the bit, namely "0" and "1", and the two states may indicate the following information as shown in Table 1 below.

[0063]

Table 1

[0064] The first state "0" in Table 1 indicates that the PUSCH transmission is associated with the first SRS resource set among the plurality of SRS resource sets whose usage is set to "codebook" or "non-codebook". The UE may determine the beam of the PUSCH transmission based on the first SRS resource set. Specifically, when the SRS resource set configured for PUSCH transmission is not configured to follow the common beam indicated for UL transmission, the beam of the first SRS resource set may be associated with a TCI state group, and there may be one common beam among at least one common beam that is similarly associated with the same TCI state group, and this common beam is determined as the common beam for PUSCH transmission. In other words, the beam of the first SRS resource set and the common beam used for PUSCH transmission of at least one common beam are associated with the same TCI state group.

[0065] In some other cases, when the SRS resource set configured for PUSCH transmission is configured to follow the common beam indicated for UL transmission, the beam of the first SRS resource set may be the first common beam among at least one common beam, and this beam is determined as the common beam for PUSCH transmission. That is, the beam of the first SRS resource set and the common beam used for PUSCH transmission of at least one common beam are the same.

[0066] The second state "1" in Table 1 indicates that the PUSCH transmission is associated with at least two of the multiple SRS resource sets whose usage is set to "codebook" or "non-codebook". For each PUSCH transmission opportunity (or each opportunity for PUSCH transmission), if the SRS resource set configured for PUSCH transmission is not configured to follow the common beam indicated for UL transmission, the beam of the SRS resource set associated with the PUSCH transmission opportunity and the common beam used for the PUSCH transmission opportunity of at least one common beam are associated with the same TCI state group. For example, for the first PUSCH transmission opportunity, it can be associated with the first (or second, third, etc.) SRS resource set among the multiple SRS resource sets whose usage is set to "codebook" or "non-codebook". The beam of the first SRS resource set may be associated with a certain TCI state group, and among at least one common beam, there may be a common beam that is similarly associated with the same TCI state group, and this common beam is determined as the common beam for the first PUSCH transmission opportunity.

[0067] In some other cases, when the SRS resource set configured for PUSCH transmission is configured to follow the common beam indicated for UL transmission, the beams of the first SRS resource set and the second SRS resource set may be the first common beam and the second common beam of at least one common beam respectively, and the first common beam is determined as the common beam for the first PUSCH transmission opportunity. That is, the beam of the first SRS resource set and the common beam used for the first PUSCH transmission opportunity of at least one common beam are the same.

[0068] In an embodiment, two common beams and two SRS resource sets are configured for PUSCH transmission, and the indication information, such as the SRS resource set indicator, may include 1 bit. Therefore, there are two states of the bit, such as "0" and "1", and the two states may indicate the following information as shown in Table 2 below.

[0069]

Table 2

[0070] The first state "0" in Table 2 indicates that the PUSCH transmission is associated with the first SRS resource set of the two SRS resource sets whose usage is set to "codebook" or "non-codebook". The UE may determine the beam of the PUSCH transmission based on the first SRS resource set. Specifically, when the SRS resource set configured for PUSCH transmission is not configured to follow the common beam indicated for UL transmission, the beam of the first SRS resource set may be associated with a certain TCI state group, and among the two common beams, there may be a common beam associated with the same TCI state group, and this common beam is determined as the common beam for PUSCH transmission. In other words, the beam of the first SRS resource set and the common beam used for PUSCH transmission of the two common beams are associated with the same TCI state group.

[0071] In some other cases, when the SRS resource set configured for PUSCH transmission is configured to follow the common beam indicated for UL transmission, the beam of the first SRS resource set may be the first common beam of the two common beams, and this beam is determined as the common beam for PUSCH transmission. That is, the beam of the first SRS resource set and the common beam used for PUSCH transmission of the two common beams are the same.

[0072] The second state "1" in Table 2: PUSCH transmission is associated with two SRS resource sets whose usage is set to "codebook" or "non-codebook". PUSCH transmission is associated with two of the multiple SRS resource sets whose usage is set to "codebook" or "non-codebook". For each PUSCH transmission opportunity (or each opportunity for PUSCH transmission), if the SRS resource set configured for PUSCH transmission is not configured to follow the common beam indicated for UL transmission, the beam of the SRS resource set associated with the PUSCH transmission opportunity and the common beam used for the PUSCH transmission opportunity of the two common beams are associated with the same TCI state group. For example, for the first PUSCH transmission opportunity, it may be associated with the first (or second) SRS resource set of the multiple SRS resource sets whose usage is set to "codebook" or "non-codebook". The beam of the first SRS resource set may be associated with a TCI state group, and among the two common beams, there may be a common beam that is similarly associated with the same TCI state group, and this common beam is determined as the common beam for the first PUSCH transmission opportunity.

[0073] In some other cases, when the SRS resource set configured for PUSCH transmission is configured to follow the common beam indicated for UL transmission, the beams of the first SRS resource set and the second SRS resource set may be the first common beam and the second common beam of the two common beams respectively, and the first common beam is determined as the common beam for the first PUSCH transmission opportunity. That is, the beam of the first SRS resource set and the common beam used for the first PUSCH transmission opportunity of the two common beams are the same.

[0074] The UE may determine the beam for PUSCH transmission in a manner similar to that described for Table 1, and the details are omitted here.

[0075] In some other embodiments, the indication information, such as the SRS resource set indicator, may include 2 bits. There are four states of the 2 bits, namely "00", "01", "10", and "11", and the four states may indicate the following information as shown in Table 3 below.

[0076]

Table 3

[0077] The first state "00" in Table 3 indicates that the PUSCH transmission is associated with the first SRS resource set among a plurality of SRS resource sets whose usage is set to "codebook" or "non-codebook". The UE may determine the beam for the PUSCH transmission based on the first SRS resource set. Specifically, when the SRS resource set configured for the PUSCH transmission is not configured to follow the common beam indicated for the UL transmission, the beam of the first SRS resource set may be associated with a certain TCI state group, and there may be a common beam among at least one common beam that is also associated with the same TCI state group, and this common beam is determined as the common beam for the PUSCH transmission. In other words, the beam of the first SRS resource set and the common beam used for the PUSCH transmission of at least one common beam are associated with the same TCI state group.

[0078] In some other cases, when the SRS resource set configured for the PUSCH transmission is configured to follow the common beam indicated for the UL transmission, the beam of the first SRS resource set may be the first common beam among at least one common beam, and this beam is determined as the common beam for the PUSCH transmission. That is, the beam of the first SRS resource set and the common beam used for the PUSCH transmission of at least one common beam are the same.

[0079] The second state "01" in Table 3 indicates that PUSCH transmission is associated with a second SRS resource set among a plurality of SRS resource sets whose usage is set to "codebook" or "non-codebook". The UE may determine the beam for PUSCH transmission based on the second SRS resource set. Specifically, if the SRS resource set configured for PUSCH transmission is not configured to follow the common beam indicated for UL transmission, the beam of the second SRS resource set may be associated with a certain TCI state group, and there may be a common beam among at least one common beam that is also associated with the same TCI state group, and this common beam is determined as the common beam for PUSCH transmission. In other words, the beam of the second SRS resource set and the common beam used for PUSCH transmission of at least one common beam are associated with the same TCI state group.

[0080] In some other cases, if the SRS resource set configured for PUSCH transmission is configured to follow the common beam indicated for UL transmission, the beam of the second SRS resource set may be the second common beam among at least one common beam, and this beam is determined as the common beam for PUSCH transmission. That is, the beam of the second SRS resource set and the common beam used for PUSCH transmission of at least one common beam are the same.

[0081] The third state "10" in Table 3 indicates that the PUSCH transmission is associated with at least two of a plurality of SRS resource sets whose usage is set to "codebook" or "non - codebook". Among the PUSCH transmission opportunities, the first PUSCH transmission opportunity is associated with the first SRS resource set among the plurality of SRS resource sets. For each PUSCH transmission opportunity (or each opportunity of PUSCH transmission including the first PUSCH transmission opportunity), if the SRS resource set configured for PUSCH transmission is not configured to follow the common beam indicated for UL transmission, the beam of the SRS resource set associated with the PUSCH transmission opportunity and the common beam used for the PUSCH transmission opportunity of at least one common beam are associated with the same TCI state group. For example, the beam of the first SRS resource set may be associated with a certain TCI state group, and among at least one common beam, there may be a common beam that is similarly associated with the same TCI state group, and this common beam is determined as the common beam of the first PUSCH transmission opportunity.

[0082] In some other cases, when the SRS resource set configured for PUSCH transmission is configured to follow the common beam indicated for UL transmission, the beams of the first SRS resource set and the second SRS resource set may be the first common beam and the second common beam among at least one common beam respectively, and the first common beam is determined as the common beam of the first PUSCH transmission opportunity. That is, the beam of the first SRS resource set and the common beam used for the first PUSCH transmission opportunity of at least one common beam are the same.

[0083] In some embodiments, the first PUSCH transmission opportunity can be a PUSCH transmission associated with the earliest start symbol, the smallest start resource block (RB), the CDM group with the smallest index, or the CDM group with the smallest DMRS port index among all PUSCH transmission opportunities.

[0084] The fourth state "11" in Table 3 (Table 3) indicates that the PUSCH transmission is associated with at least two of a plurality of SRS resource sets whose usage is set to "codebook" or "non-codebook". Among the PUSCH transmission opportunities, the first PUSCH transmission opportunity is associated with the second SRS resource set among the plurality of SRS resource sets. For each PUSCH transmission opportunity (or each opportunity of PUSCH transmission including the first PUSCH transmission opportunity), if the SRS resource set configured for PUSCH transmission is not configured to follow the common beam indicated for UL transmission, the beam of the SRS resource set associated with the PUSCH transmission opportunity and the common beam used for the PUSCH transmission opportunity of at least one common beam are associated with the same TCI state group. For example, the beam of the second SRS resource set may be associated with a certain TCI state group, and among at least one common beam, there may be a common beam that is also associated with the same TCI state group, and this common beam is determined as the common beam of the first PUSCH transmission opportunity.

[0085] In some other cases, when the SRS resource set configured for PUSCH transmission is configured to follow the common beam indicated for UL transmission, the beams of the first SRS resource set and the second SRS resource set may be the first common beam and the second common beam among at least one common beam respectively, and the second common beam is determined as the common beam of the first PUSCH transmission opportunity. That is, the beam of the second SRS resource set and the common beam used for the first PUSCH transmission opportunity of at least one common beam are the same.

[0086] In one embodiment, two common beams and two SRS resource sets are configured for PUSCH transmission, and the indication information, i.e., the SRS resource indicator, may include 2 bits. There are four states of the 2 bits, namely "00", "01", "10", and "11", and the four states may indicate the following information as shown in Table 4 below.

[0087]

Table 4

[0088] The first state "00" in Table 4 indicates that the PUSCH transmission is associated with the first SRS resource set among the two SRS resource sets whose usage is set to "codebook" or "non-codebook". The UE may determine the beam of the PUSCH transmission based on the first SRS resource set. Specifically, if the SRS resource set configured for PUSCH transmission is not configured to follow the common beam indicated for UL transmission, the beam of the first SRS resource set may be associated with a certain TCI state group, and among the two common beams, there may be a common beam that is also associated with the same TCI state group, and this common beam is determined as the common beam for PUSCH transmission. In other words, the beam of the first SRS resource set and the common beam used for PUSCH transmission of the two common beams are associated with the same TCI state group.

[0089] In some other cases, if the SRS resource set configured for PUSCH transmission is configured to follow the common beam indicated for UL transmission, the beam of the first SRS resource set may be the first common beam among the two common beams, and this beam is determined as the common beam for PUSCH transmission. That is, the beam of the first SRS resource set and the common beam used for PUSCH transmission of the two common beams are the same.

[0090] The second state "01" in Table 4 indicates that PUSCH transmission is associated with the second SRS resource set among the two SRS resource sets whose usage is set to "codebook" or "non-codebook". The UE may determine the beam for PUSCH transmission based on the second SRS resource set. Specifically, when the SRS resource set configured for PUSCH transmission is not configured to follow the common beam indicated for UL transmission, the beam of the second SRS resource set may be associated with a certain TCI state group, and among the two common beams, there may be a common beam that is similarly associated with the same TCI state group, and this common beam is determined as the common beam for PUSCH transmission. In other words, the beam of the second SRS resource set and the common beam used for PUSCH transmission of the two common beams are associated with the same TCI state group.

[0091] In some other cases, when the SRS resource set configured for PUSCH transmission is configured to follow the common beam indicated for UL transmission, the beam of the second SRS resource set may be the second common beam among the two common beams, and this beam is determined as the common beam for the PUSCH transmission opportunity. That is, the beam of the second SRS resource set and the common beam used for PUSCH transmission of the two common beams are the same.

[0092] The third state "10" in Table 4 indicates that the PUSCH transmission is associated with two SRS resource sets whose usage is set to "codebook" or "non-codebook". Among the PUSCH transmission opportunities, the first PUSCH transmission opportunity is associated with the first SRS resource set among the two SRS resource sets. For each PUSCH transmission opportunity (or each opportunity of PUSCH transmission including the first PUSCH transmission opportunity), if the SRS resource set configured for PUSCH transmission is not configured to follow the common beam indicated for UL transmission, the beam of the SRS resource set associated with the PUSCH transmission opportunity and the common beam used for the PUSCH transmission opportunity of the two common beams are associated with the same TCI state group. For example, the beam of the first SRS resource set may be associated with a certain TCI state group, and among the two common beams, there may be a common beam that is similarly associated with the same TCI state group, and this common beam is determined as the common beam for the first PUSCH transmission opportunity.

[0093] In some other cases, when the SRS resource set configured for PUSCH transmission is configured to follow the common beam indicated for UL transmission, the beams of the first SRS resource set and the second SRS resource set may be the first common beam and the second common beam among the two common beams respectively, and the first common beam is determined as the common beam for the first PUSCH transmission opportunity. That is, the beam of the first SRS resource set and the common beam used for the first PUSCH transmission opportunity of the two common beams are the same.

[0094] The fourth state "11" in Table 4 indicates that the PUSCH transmission is associated with two SRS resource sets with the usage set to "codebook" or "non-codebook". Among the PUSCH transmission opportunities, the first PUSCH transmission opportunity is associated with the second SRS resource set among the two SRS resource sets. For each PUSCH transmission opportunity (or each opportunity of PUSCH transmission including the first PUSCH transmission opportunity), if the SRS resource set configured for PUSCH transmission is not configured to follow the common beam indicated for UL transmission, the beam of the SRS resource set associated with the PUSCH transmission opportunity and the common beams used for the PUSCH transmission opportunities of the two common beams are associated with the same TCI state group. For example, the beam of the second SRS resource set may be associated with a certain TCI state group, and among the two common beams, there may be a common beam that is similarly associated with the same TCI state group, and this common beam is determined as the common beam for the first PUSCH transmission opportunity.

[0095] In some other cases, when the SRS resource set configured for PUSCH transmission is configured to follow the common beam indicated for UL transmission, the beams of the first SRS resource set and the second SRS resource set may be the first common beam and the second common beam of the two common beams respectively, and the second common beam is determined as the common beam for the first PUSCH transmission opportunity. That is, the beam of the second SRS resource set and the common beam used for the first PUSCH transmission opportunity of the two common beams are the same.

[0096] Strategy 1-1B In this approach, at least one common beam and a plurality of SRS resource sets are configured for PUSCH transmission, and the network may configure indication information indicating the association of PUSCH transmission with at least a part of at least one common beam configured for PUSCH transmission. For example, the network may configure a beam indicator to indicate the associated beam for PUSCH transmission. It should be noted that the network may configure either an SRS resource set indicator or a beam indicator.

[0097] The indication information, that is, the beam indicator, may include 1 bit. There are two states of the bit, namely "0" and "1", and the two states may indicate the following information as shown in Table 5 below.

[0098]

Table 5

[0099] The first state "0" in Table 5 indicates that the PUSCH transmission is associated with the first common beam among at least one common beam. The UE may determine the SRS resource set among the plurality of SRS resource sets based on the first common beam. Specifically, if the SRS resource set configured for PUSCH transmission is not configured to follow the common beam indicated for UL transmission, the first common beam may be associated with a TCI state group, and there may be an SRS resource set among the plurality of SRS resource sets whose beam is associated with the same TCI state group, and the PUSCH transmission is associated with this SRS resource set. That is, the beam of the SRS resource set related to the PUSCH transmission of the first common beam and the plurality of SRS resource sets is associated with the same TCI state group.

[0100] In some other cases, when the SRS resource set configured for PUSCH transmission is configured to follow the common beam indicated for UL transmission, the beam of the first common beam and a certain SRS resource set among the plurality of SRS resource sets may be the same beam, and the PUSCH transmission is associated with this SRS resource set.

[0101] The second state "1" in Table 5 indicates that the PUSCH transmission is associated with at least two common beams. In this state, at least two common beams and a plurality of SRS resource sets are configured for PUSCH transmission.

[0102] The UE may determine an SRS resource set of the plurality of SRS resource sets based on at least two common beams.

[0103] For each PUSCH transmission opportunity (or each opportunity of PUSCH transmission), when the SRS resource set configured for PUSCH transmission is not configured to follow the common beam indicated for UL transmission, the beam of that common beam among at least two common beams and the SRS resource set related to the PUSCH transmission of the plurality of SRS resource sets is associated with the same TCI state group. For example, for the first PUSCH transmission opportunity, it may be associated with the first (or second, third, etc.) common beam among at least two common beams, and the first common beam is associated with the TCI state group. Among the plurality of SRS resource sets, there may be an SRS resource set whose beam is similarly associated with the same TCI state group. Therefore, this SRS resource set is associated with the PUSCH transmission opportunity.

[0104] In some other cases, when the SRS resource set configured for PUSCH transmission is configured to follow the common beam indicated for UL transmission, the beam of the first (or second, third, etc.) common beam and a certain SRS resource set among the plurality of SRS resource sets may be the same, and the PUSCH transmission is associated with this SRS resource set.

[0105] In an embodiment, two common beams and two SRS resource sets are configured for PUSCH transmission, and the indication information, i.e., the beam indicator, may include 1 bit. There are two states of the bit, i.e., "0" and "1", and the two states may indicate the following information as shown in Table 6 below.

[0106] [Table 6]

[0107] The first state "0" in Table 6 indicates that the PUSCH transmission is associated with the first common beam among the two common beams. The UE may determine an SRS resource set among the two SRS resource sets based on the first common beam. Specifically, when the SRS resource set configured for PUSCH transmission is not configured to follow the common beam indicated for UL transmission, the first common beam may be associated with a TCI state group, and there may be one of the two SRS resource sets whose beam is associated with the same TCI state group, and the PUSCH transmission is associated with this SRS resource set. That is, the beam of the first common beam and the SRS resource set related to the PUSCH transmission of the two SRS resource sets is associated with the same TCI state group.

[0108] In some other cases, when the SRS resource set configured for PUSCH transmission is configured to follow the common beam indicated for UL transmission, the beam of the first common beam and one of the two SRS resource sets may be the same beam, and the PUSCH transmission is associated with this SRS resource set.

[0109] The second state "1" in Table 6 indicates that the PUSCH transmission is associated with two common beams. The UE may determine the SRS resource set out of the two SRS resource sets based on the two common beams.

[0110] For each PUSCH transmission opportunity (or each opportunity of PUSCH transmission), when the SRS resource set configured for PUSCH transmission is not configured to follow the common beam indicated for UL transmission, the beam of that common beam out of the two common beams and the SRS resource set related to the PUSCH transmission of the two SRS resource sets are associated with the same TCI state group. For example, for the first PUSCH transmission opportunity, it may be associated with the first (or second) common beam of the two common beams, and the first common beam is associated with the TCI state group. Among the two SRS resource sets, there may be an SRS resource set whose beam is similarly associated with the same TCI state group. Therefore, this SRS resource set is associated with the PUSCH transmission opportunity.

[0111] In some other cases, when the SRS resource set configured for PUSCH transmission is configured to follow the common beam indicated for UL transmission, the beam of the first (or second) common beam and one of the two SRS resource sets may be the same beam, and the PUSCH transmission is associated with this SRS resource set.

[0112] In some other embodiments, the indication information, i.e., the beam indicator, may include 2 bits. There are 4 states of 2 bits, namely "00", "01", "10", and "11", and the 4 states may indicate the following information as shown in Table 7 below.

[0113]

Table 7

[0114] The first state "00" in Table 7 indicates that the PUSCH transmission is associated with the first common beam among at least one common beam. The UE may determine an SRS resource set among a plurality of SRS resource sets based on the first common beam in a manner similar to the first state "0" in Table 5, and the details are omitted here.

[0115] In the following states "01", "10", and "11" in Table 7, at least two common beams are configured for PUSCH transmission.

[0116] The second state "01" in Table 7 indicates that the PUSCH transmission is associated with the second common beam among at least two common beams. The UE may determine an SRS resource set among a plurality of SRS resource sets based on the second common beam.

[0117] The third state "10" in Table 7 indicates that the PUSCH transmission is associated with at least two common beams. Among the PUSCH transmission opportunities, the first PUSCH transmission opportunity is associated with the first common beam.

[0118] For each PUSCH transmission opportunity (or each opportunity of PUSCH transmission including the first PUSCH transmission opportunity), if the SRS resource set configured for PUSCH transmission is not configured to follow the common beam indicated for UL transmission, the beam of that common beam among at least two common beams and the SRS resource set related to PUSCH transmission of a plurality of SRS resource sets is associated with the same TCI state group. For example, for the first PUSCH transmission opportunity, it may be associated with the first (or second, third, etc.) common beam among at least two common beams, and the first common beam is associated with the TCI state group. Among the plurality of SRS resource sets, there may be an SRS resource set whose beam is similarly associated with the same TCI state group. Therefore, this SRS resource set is associated with the PUSCH transmission opportunity.

[0119] In some other cases, if the SRS resource set configured for PUSCH transmission is configured to follow the common beam indicated for UL transmission, the beam of the first (or second, third, etc.) common beam and a certain SRS resource set among the plurality of SRS resource sets may be the same beam, and the PUSCH transmission is associated with this SRS resource set.

[0120] The fourth state "11" in Table 7 indicates that the PUSCH transmission is associated with at least two common beams. Among the PUSCH transmission opportunities, the first PUSCH transmission opportunity is associated with the second common beam.

[0121] For each PUSCH transmission opportunity (or each opportunity of PUSCH transmission including the first PUSCH transmission opportunity), if the SRS resource set configured for PUSCH transmission is not configured to follow the common beam indicated for UL transmission, the beam of that common beam among at least two common beams and the SRS resource set related to PUSCH transmission of the plurality of SRS resource sets is associated with the same TCI state group. For example, for the first PUSCH transmission opportunity, it may be associated with the first (or second, third, etc.) common beam among at least two common beams, and the first common beam is associated with the TCI state group. Among the plurality of SRS resource sets, there may be an SRS resource set whose beam is similarly associated with the same TCI state group. Therefore, this SRS resource set is associated with the PUSCH transmission opportunity.

[0122] In some other cases, if the SRS resource set configured for PUSCH transmission is configured to follow the common beam indicated for UL transmission, the beam of the first (or second, third, etc.) common beam and a certain SRS resource set among the plurality of SRS resource sets may be the same beam, and the PUSCH transmission is associated with this SRS resource set.

[0123] In an embodiment, two common beams and two SRS resource sets are configured for PUSCH transmission, and the indication information, i.e., the beam indicator, may include 2 bits. There are 4 states of 2 bits, namely, "00", "01", "10", and "11", and the 4 states may indicate the following information as shown in Table 8 below.

[0124]

Table 8

[0125] The first state "00" in Table 8 indicates that PUSCH transmission is associated with the first common beam among two common beams. The UE may determine the SRS resource set among two SRS resource sets based on the first common beam in a manner similar to the first state "0" in Table 5, and the details are omitted here.

[0126] In the following states "01", "10", and "11" in Table 8, at least two common beams are configured for PUSCH transmission.

[0127] The second state "01" in Table 8 indicates that PUSCH transmission is associated with the second common beam among at least two common beams. The UE may determine the SRS resource set among two SRS resource sets based on the second common beam.

[0128] The third state "10" in Table 8 indicates that PUSCH transmission is associated with two common beams. Among the PUSCH transmission opportunities, the first PUSCH transmission opportunity is associated with the first common beam.

[0129] For each PUSCH transmission opportunity (or each opportunity of PUSCH transmission including the first PUSCH transmission opportunity), if the SRS resource set configured for PUSCH transmission is not configured to follow the common beam indicated for UL transmission, the beam of that common beam among the two common beams and the SRS resource set related to PUSCH transmission of the two SRS resource sets are associated with the same TCI state group. For example, for the first PUSCH transmission opportunity, it may be associated with the first (or second) common beam among the two common beams, and the first common beam is associated with the TCI state group. Among the two SRS resource sets, there may be an SRS resource set whose beam is similarly associated with the same TCI state group. Therefore, this SRS resource set is associated with the PUSCH transmission opportunity.

[0130] In some other cases, when the SRS resource set configured for PUSCH transmission is configured to follow the common beam indicated for UL transmission, the beam of the first (or second) common beam and one of the two SRS resource sets may be the same beam, and the PUSCH transmission is associated with this SRS resource set.

[0131] The fourth state "11" in Table 8 indicates that the PUSCH transmission is associated with two common beams. Among the PUSCH transmission opportunities, the first PUSCH transmission opportunity is associated with the second common beam.

[0132] For each PUSCH transmission opportunity (or each opportunity of PUSCH transmission including the first PUSCH transmission opportunity), if the SRS resource set configured for PUSCH transmission is not configured to follow the common beam indicated for UL transmission, the beam of that common beam among the two common beams and the SRS resource set related to the PUSCH transmission of the two SRS resource sets are associated with the same TCI state group. For example, for the first PUSCH transmission opportunity, it may be associated with the first (or second, third, etc.) common beam among the two common beams, and the first common beam is associated with the TCI state group. Among the two SRS resource sets, there may be an SRS resource set whose beam is similarly associated with the same TCI state group. Therefore, this SRS resource set is associated with the PUSCH transmission opportunity.

[0133] In some other cases, when the SRS resource set configured for PUSCH transmission is configured to follow the common beam indicated for UL transmission, the beam of the first (or second) common beam and one of the two SRS resource sets may be the same beam, and the PUSCH transmission is associated with this SRS resource set.

[0134] Scenario 2 In this scenario, in the configuration of PUSCH transmission, there is no SRS resource indication information (e.g., srs-ResourceIndicator), or the SRS resource indication information does not include any SRS resource indicator value, which means that only one SRS resource is configured for each SRS resource set configured for PUSCH transmission. The UE may receive second indication information indicating the PUSCH mode of PUSCH transmission, and the PUSCH transmission is associated with at least two common beams and at least two SRS resource sets. Specifically, the second indication information may indicate one of the following. - The PUSCH transmission is configured using at least two repetitions. - The PUSCH transmission is configured using frequency division multiplexing (FDM) mode A, FDM mode B, or single frequency network (SFN) mode. - The PUSCH transmission is indicated using at least two demodulation reference signals (DMRS) ports from two different CDM groups.

[0135] In other words, the second indication information indicates that there are a plurality of PUSCH transmission opportunities for transmission. For each PUSCH transmission opportunity, if the SRS resource set configured for PUSCH transmission is not configured to follow the common beam indicated for UL transmission, the beam of that common beam among at least two common beams and the SRS resource set related to PUSCH transmission of at least two SRS resource sets is associated with the same TCI state group. For example, for the first PUSCH transmission opportunity, it may be associated with the first (or second, or third, etc.) common beam among at least two common beams, and the first common beam is associated with the TCI state group. Among at least two SRS resource sets, there may be an SRS resource set whose beam is similarly associated with the same TCI state group. Therefore, this SRS resource set is associated with the PUSCH transmission opportunity. Alternatively, if the SRS resource set configured for PUSCH transmission is configured to follow the common beam indicated for UL transmission, the beam of that common beam among at least two common beams and the beam of the SRS resource set related to PUSCH transmission of at least two SRS resource sets are the same beam.

[0136] In one embodiment, PUSCH transmission is associated with two common beams and two SRS resource sets. For each PUSCH transmission opportunity, if the SRS resource set configured for PUSCH transmission is not configured to follow the common beam indicated for UL transmission, the beam of that common beam among the two common beams and the SRS resource set associated with PUSCH transmission of the two SRS resource sets is associated with the same TCI state group. For example, for the first PUSCH transmission opportunity, it may be associated with the first (or second) common beam among at least two common beams, and the first common beam is associated with a TCI state group. Among the two SRS resource sets, there may be an SRS resource set whose beam is similarly associated with the same TCI state group. Thus, this SRS resource set is associated with the PUSCH transmission opportunity. Alternatively, if the SRS resource set configured for PUSCH transmission is configured to follow the common beam indicated for UL transmission, the beam of that common beam among the two common beams and the beam of the SRS resource set associated with PUSCH transmission of the two SRS resource sets are the same beam.

[0137] If the UE does not receive the second indication information, the PUSCH transmission is performed using the first common beam among at least two common beams, is associated with one SRS resource set among at least two SRS resource sets, and if the SRS resource set configured for PUSCH transmission is not configured to follow the common beam indicated for UL transmission, the beam of the SRS resource set and the common beam are associated with the same TCI state group, or if the SRS resource set configured for PUSCH transmission is configured to follow the common beam indicated for UL transmission, the beam of the SRS resource set is the first common beam.

[0138] Scenario 3 In Scenario 3, in the configuration of PUSCH transmission, there is no SRS resource indication information (e.g., srs-ResourceIndicator), or the SRS resource indication information does not include any SRS resource indicator value, which means that only one SRS resource is configured for each SRS resource set for PUSCH transmission. The PUSCH transmission is configured to be associated with one common beam, regardless of how many common beams are indicated for UL transmission. In some cases, only one common beam is indicated for UL transmission, and the PUSCH transmission is associated with that one common beam. In some other cases, two or more common beams are indicated for UL transmission, and the PUSCH transmission is associated with the first common beam among the two or more common beams. The PUSCH transmission may be configured to be associated with multiple SRS resource sets. Among these SRS resource sets, there may be an SRS resource set in which the SRS resource set configured for PUSCH transmission is not configured to follow the common beam indicated for UL transmission, and the beam of that SRS resource set and one common beam (or the first common beam) are associated with the same TCI group, or when the SRS resource set configured for PUSCH transmission is configured to follow the common beam indicated for UL transmission, the beam of that SRS resource set among the SRS resource sets and one common beam (or the first common beam) are the same.

[0139] For all the above scenarios, if only one common beam is indicated for UL transmission, the PUSCH transmission shall fallback to a single TRP PUSCH transmission regardless of the configuration information. The PUSCH transmission is associated with the common beam. The PUSCH transmission is associated with one of the multiple SRS resource sets, and if the beam of one SRS resource set and one common beam are not configured to follow the common beam indicated for UL transmission by the SRS resource set configured for PUSCH transmission, they are associated with the same TCI group, or if the SRS resource set configured for PUSCH transmission is configured to follow the common beam indicated for UL transmission, the beam of that SRS resource set among the SRS resource sets and one common beam are the same.

[0140] Scenario 4 In this scenario, the UE may receive a third piece of indication information indicating one or more SRS resource indicator values. For example, the third piece of indication information may include one or two SRS resource indicators, such as srs-ResourceIndicator. The number of common beams related to the PUSCH transmission may be indicated by the third piece of indication information. For example, one srs-ResourceIndicator may indicate that the PUSCH transmission may be associated with only one common beam. Two srs-ResourceIndicators may indicate that the PUSCH transmission may be associated with one or two common beams.

[0141] Case 1:

[0142] In this case, the UE does not receive the first piece of indication information, i.e., the SRS resource set indicator or the beam indicator, and the UE receives a third piece of indication information that may include zero, one, or two srs-ResourceIndicators. If the third piece of indication information includes zero srs-ResourceIndicators, the third piece of indication information may not be present, and thus this case is omitted here.

[0143] Scenario 1-1:

[0144] When the third indication information indicates one SRS resource indicator value, i.e., one srs-ResourceIndicator is configured, the PUSCH transmission can be associated with only one common beam. When two common beams are indicated for UL transmission, the PUSCH transmission can be sent by the first common beam among the two common beams. When only one common beam is indicated, the PUSCH transmission can be sent by that only one common beam. Regarding the SRS resource set, if the beam of the SRS resource set related to the PUSCH transmission and its one common beam (or the first common beam among the two common beams) are not configured to follow the common beam indicated for UL transmission, they are associated with the same TCI state group, or if the SRS resource set configured for the PUSCH transmission is configured to follow the common beam indicated for UL transmission, the beam of the SRS resource set related to the PUSCH transmission and its one common beam (or the first common beam among the two common beams) are the same beam. Furthermore, the indicator, i.e., srs-ResourceIndicator, is associated with the SRS resource set.

[0145] Scenario 1-2:

[0146] When the third indication information indicates two SRS resource indicator values, i.e., two indicators, i.e., srs-ResourceIndicator is configured, the PUSCH transmission can be associated with two common beams according to the common beam indicated for UL transmission. The first indicator, i.e., the first srs-ResourceIndicator, may be associated with the first SRS resource set, and the second indicator, i.e., the second srs-ResourceIndicator, may be associated with the second SRS resource set.

[0147] If two common beams are also indicated for UL transmission, PUSCH transmission may be associated with those two common beams. For each PUSCH transmission opportunity, if the beam of the SRS resource set associated with the PUSCH transmission opportunity and the common beam used for the PUSCH transmission opportunity of at least one common beam are not configured to follow the common beam indicated for UL transmission by the SRS resource set configured for PUSCH transmission, they are associated with the same TCI state group. Alternatively, the beam of the SRS resource set and the common beam used for the PUSCH transmission opportunity are the same if the SRS resource set configured for PUSCH transmission is configured to follow the common beam indicated for UL transmission.

[0148] The first PUSCH transmission opportunity may be associated with the first common beam, or the first PUSCH transmission opportunity is associated with the first SRS resource set (which may be indicated by the first srs-ResourceIndicator). In some embodiments, the first PUSCH transmission opportunity may be a PUSCH transmission associated with the earliest start symbol, the smallest start RB, the CDM group with the smallest index, or the CDM group with the smallest DMRS port index among all PUSCH transmission opportunities.

[0149] If only one common beam is indicated for UL transmission, the PUSCH transmission may be associated with that single common beam. The beam of the SRS resource set associated with the PUSCH transmission and that single common beam are associated with the same TCI state group if the SRS resource set configured for the PUSCH transmission does not follow the common beam indicated for UL transmission, or are the same if the beam of the SRS resource set associated with the PUSCH transmission and that single common beam are configured to follow the common beam indicated for UL transmission for the SRS resource set configured for the PUSCH transmission. The PUSCH transmission is associated with one indicator (i.e., srs-ResourceIndicator) related to the SRS resource set.

[0150] Case 2:

[0151] In this case, the UE receives not only the first indication information, i.e., the SRS resource set indicator or the beam indicator, but also the third indication information, which may include zero, one, or two srs-ResourceIndicators. If the third indication information includes zero srs-ResourceIndicators, the third indication information may be absent, and thus the UE may determine the common beam for PUSCH transmission based only on the first indication information.

[0152] Case 2-1

[0153] If the third indication information indicates one SRS resource indicator value, i.e., one srs-ResourceIndicator is configured, the first indication information may indicate only the state related to one SRS resource set. For example, only the state of the SRS resource set indicator indicating that the PUSCH transmission is associated with one SRS resource set may be configured for the PUSCH transmission, or only the state of the beam indicator indicating that the PUSCH transmission is associated with one beam may be configured for the PUSCH transmission.

[0154] If only one common beam is indicated for UL transmission, the PUSCH transmission may be associated with that single common beam. The beam of the SRS resource set related to the PUSCH transmission and that single common beam are associated with the same TCI state group if the SRS resource set configured for the PUSCH transmission does not follow the common beam indicated for UL transmission, or are the same beam if the SRS resource set configured for the PUSCH transmission follows the common beam indicated for UL transmission. The PUSCH transmission is associated with an indicator (i.e., srs-ResourceIndicator).

[0155] If two common beams are indicated for UL transmission, the PUSCH transmission may be transmitted by one of the two common beams according to the first indication. Regarding the SRS resource set related to the PUSCH transmission, the beam of the SRS resource set related to the PUSCH transmission and that one common beam (or the first common beam of the two common beams) are associated with the same TCI state group if the SRS resource set configured for the PUSCH transmission does not follow the common beam indicated for UL transmission, or are the same beam if the SRS resource set configured for the PUSCH transmission follows the common beam indicated for UL transmission. Further, the indicator, i.e., srs-ResourceIndicator, is associated with the SRS resource set related to the PUSCH transmission.

[0156] Case 2-2

[0157] When the third indication information indicates two SRS resource indicator values, i.e., when two indicators, i.e., srs-ResourceIndicator, are configured, the first indication information may indicate any state related to one or two SRS resource sets. And the first indicator (the first srs-ResourceIndicator) and the second indicator (the second srs-ResourceIndicator) may be associated with the first SRS resource set and the second SRS resource set, respectively. For example, the state of the SRS resource set indicator indicating that PUSCH transmission is associated with one SRS resource set or two SRS resource sets may be configured for PUSCH transmission, and the state of the beam indicator indicating that PUSCH transmission is associated with one beam or two beams may be configured for PUSCH transmission.

[0158] When only one common beam is indicated for UL transmission, PUSCH transmission may be associated with only that one common beam. The beam of the SRS resource set related to PUSCH transmission and that one common beam are associated with the same TCI state group if the SRS resource set configured for PUSCH transmission is not configured to follow the common beam indicated for UL transmission, or the beam of the SRS resource set related to PUSCH transmission and that one common beam are the same if the SRS resource set configured for PUSCH transmission is configured to follow the common beam indicated for UL transmission. PUSCH transmission is associated with one indicator (i.e., srs-ResourceIndicator) related to the SRS resource set.

[0159] When two common beams are indicated for UL transmission, PUSCH transmission is associated with one or two common beams and one or two SRS resource sets, respectively, according to the first configuration information as described in Policy 1 above.

[0160] When PUSCH transmission is associated with only one SRS resource set according to the first configuration information, the PUSCH transmission is associated with only one indicator related to the SRS resource set, for example, the first srs-ResourceIndicator, and other indicators, for example, the second srs-ResourceIndicator are not used.

[0161] Figure 3 shows a method performed by a UE for CG type 1 PUSCH transmission according to some embodiments of the present disclosure.

[0162] In operation 301, the UE may receive configuration information indicating CG type 1 PUSCH transmission, and the configuration information includes at least one of the first indication information (for example, an SRS resource set indicator or a beam indicator as described in Scenario 1) indicating the association of the CG type 1 PUSCH transmission with at least a part of at least one common beam or the association of the CG type 1 PUSCH transmission with at least a part of a plurality of SRS resource sets configured for the CG type 1 PUSCH transmission, the second indication information (for example, the second indication information as described in Scenario 2) indicating the PUSCH scheme of the CG type 1 PUSCH transmission, or the third indication information (for example, the third indication information as described in Scenario 4) including at most two SRS resource indicator values, to indicate which common beam among at least one common beam applicable to uplink transmission in a slot is associated with the CG type 1 PUSCH transmission. In operation 302, the UE may transmit a CG type 1 PUSCH transmission in a slot based on the configuration information.

[0163] In some embodiments, the configuration information includes at least first indication information and third indication information that does not include SRS resource indicator values. When at least two common beams are applicable to uplink transmission in a slot, CG type 1 PUSCH transmission is associated with one or more of the at least two common beams and one or more of the plurality of SRS resource sets according to the first indication information. For example, the UE may receive an SRS resource set indicator or a beam indicator and may not receive the third information.

[0164] In some embodiments, the configuration information includes at least first indication information and third indication information that includes one SRS resource indicator value. When at least two common beams are applicable to uplink transmission in a slot, CG type 1 PUSCH transmission is associated with one of the at least two common beams and one of the plurality of SRS resource sets according to the first indication information and the third indication information. For example, the UE may receive an SRS resource set indicator or a beam indicator and one SRS resource indicator, such as srs-ResourceIndicator as described in Case 2-1 of Scenario 4.

[0165] In some embodiments, the configuration information includes at least first indication information and third indication information that includes two SRS resource indicator values. When two common beams are applicable to uplink transmission in a slot, CG type 1 PUSCH transmission is associated with one or more of the two common beams and one or more of the plurality of SRS resource sets according to the first indication information. For example, the UE may receive an SRS resource set indicator or a beam indicator and two SRS resource indicators, such as srs-ResourceIndicator as described in Case 2-2 of Scenario 4.
