Abstract
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 specifications, whether CG type 1 PUSCH transmission is transmitted to a single transceiver point (TRP) or 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 transmitted to a single TRP or multiple TRPs.
Summary of the Invention
Problems to be Solved by the Invention
[0003] Therefore, it is desirable to provide technical solutions for multi-transceiver point (M-TRP) PUSCH transmission, and more specifically, for M-TRP CG type 1 PUSCH transmission under a common beam framework.

Furthermore, the terms enumerated in this disclosure may change, and this should not affect the principles of this disclosure.
[0035] Figure 1 is a schematic diagram showing an exemplary wireless communication system 100 according to several embodiments of the present disclosure.
[0036] Referring to Figure 1, the wireless communication system 100 may include BS101, TRP103 (e.g., TRP103a and TRP103b), and UE105 (e.g., UE105a, UE105b, and UE105c). For brevity, only one BS101, two TRP103s, and three UE105s are shown, but it should be noted that the wireless communication system 100 may include more or fewer communication devices, apparatus, or nodes according to some other embodiments of this application.
[0037] UE105 may include computing devices such as desktop computers, laptop computers, personal digital assistants (PDAs), tablet computers, smart televisions (e.g., internet-connected televisions), set-top boxes, game consoles, security systems (including security cameras), in-vehicle computers, and network devices (e.g., routers, switches, and modems). According to some embodiments of the Disclosure, UE105 may include portable wireless communication devices, smartphones, mobile phones, flip phones, devices having subscriber identification modules, personal computers, selective call receivers, or any other devices capable of transmitting and receiving communication signals over a wireless network. In some embodiments of the Disclosure, UE101 includes wearable devices such as smartwatches, fitness bands, and optical head-mounted displays. Furthermore, UE105 may be referred to as subscriber units, mobiles, mobile stations, users, terminals, mobile terminals, wireless terminals, fixed terminals, subscriber stations, user terminals, or devices, or may be described using other terms used in the Art. UE101 may communicate with BS102 via uplink (UL) communication signals.
[0038] In some embodiments of this 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, computing devices, wearable devices, mobile devices, Internet of Things (IoT) devices, vehicles, etc.
[0039] TRP103, for example, TRP103a and TRP103b, can communicate with BS101, for example, via a backhaul link. Each of the TRP103 can service some or all of the UE105. As shown in Figure 1, TRP103a can service several mobile stations (which may include UE105a, UE105b, and UE105c) within a serving area or region (e.g., a cell or cell sector). TRP103b can service several mobile stations (which may include UE105a, UE105b, and UE105c) within a serving area or region (e.g., a cell or cell sector). In some other embodiments, TRP103a and TRP103b can service different UEs. TRP103a and TRP103b can communicate with each other, for example, via a backhaul link.
[0040] Regarding PUSCH transmission, and in particular CG type 1 PUSCH transmission, there are several conventions in R17 concerning multi-transmit / receive point (M-TRP) CG type 1 PUSCH, which are shown below. For type 1 CG-based m-TRP PUSCH iterations, introduce a second field to "rrc-ConfiguredUplinkGrant" for "pathlossReferenceIndex", "srs-ResourceIndicator", and "precodingAndNumberOfLayers". When DCI schedules a retransmission of CG-PUSCH for type 1 CG-PUSCH or type 2 CG-PUSCH (DCI with CRC scrambled with CS-RNTI and NDI=1), the same procedure as previously agreed upon for DCI activation for CG type 2 is applied while the CG configuration is configured with RRC using two fields of power control parameters, 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. - Whether to apply the first RRC configuration field "p0-PUSCH-Alpha", the second RRC configuration field "powerControlLoopToUse", or both is determined from the new DCI field (for dynamic switching) of the activated DCI, as in the case of DG-PUSCH. When a fallback DCI (DCI format 0_0) activates a type 2 CG, or when a retransmission of a type 1 or type 2 CG is scheduled and the CG configuration is RRC configured using two sets of power control parameters (two "p0-PUSCH-Alpha" and "powerControlLoopToUse"): -UE uses a first set of values for power control (first RRC configuration "p0-PUSCH-Alpha" and "powerControlLoopToUse"). When a DCI containing a new 2-bit DCI field for dynamic switching activates a type 2 CG, or schedules a retransmission of a type 1 or type 2 CG, and the CG configuration is configured with RRC using only one set of power control parameters (one "p0-PUSCH-Alpha" and "powerControlLoopToUse"): -UE expects a new DCI field for dynamic switching to be set to "00", and all PUSCH iterations to be associated with the first SRS resource set. For BWPs configured with two SRS resource sets for CB or NCB-based mTRP PUSCH iterations with Type 1 CG configurations, -If the CG consists of only one field each for "pathlossReferenceIndex", "srs-ResourceIndicator", "precodingAndNumberOfLayers", "p0-PUSCH-Alpha", and "powerControlLoopToUse", then the PUSCH iteration is associated with the first SRS resource set.
[0041] For an M-TRP type 1 CG PUSCH, when the two fields "precodingAndNumberOfLayers" and / or "srs-ResourceIndicator" exist in "rrc-ConfiguredUplinkGrant", - The two precoding pieces shown (for CB PUSCH) are determined separately using the two fields of "precodingAndNumberOfLayers". - The indicated SRI (for CB / NCB PUSCH) is determined separately using the two fields of "srs-ResourceIndicator". When both srs-ResourceSetToAddModList and srs-ResourceSetToAddModListDCI-0-2 are configured with two SRS resource sets for an mTRP type 1 CG PUSCH, the two SRS resource sets configured by srs-ResourceSetToAddModList are used to determine the SRS resource indication by the two srs-ResourceIndicator fields of the mTRP CG PUSCH. For type 1 CG-based multi-TRP push iterations: - 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, - If two SRS resource sets configured for use as either a "codebook" or a "non-codebook" are configured in srs-ResourceSetToAddModList, those two SRS resource sets are used by srs-ResourceIndicator and srs-ResourceIndicator2 to determine the SRS resource indication. - Otherwise, two SRS resource sets configured in srs-ResourceSetToAddModListDCI-0-2, which are set to be used as either "codebooks" or "non-codebooks," are used by srs-ResourceIndicator and srs-ResourceIndicator2 to determine the SRS resource indication.
[0042] For dynamic grant DG PUSCH or CG type 2 PUSCH, an SRS resource set indicator (SRI) field is present in the corresponding DCI to indicate that the PUSCH is an S-TRP PUSCH or M-TRP PUSCH. According to the above convention, whether a CG type 1 PUSCH is sent to a single TRP or two TRPs is determined by the number of configured power control parameter sets in the corresponding configuration, because if 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 present 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 configured in the configured grant PUSCH configuration (e.g., p0-PUSCH-Alpha, pathlossReferenceIndex, and powerControlLoopToUse).
[0044] In the common beam framework, the power control parameter set for CG type 1 PUSCH is not configured in the CG PUSCH configuration but is determined according to the common beam shown 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 “codebook” or “non-codebook” usage, 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 the 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, how to determine whether a PUSCH transmission, such as CG type 1, is transmitted to a single TRP or to multiple TRPs needs to be resolved, especially when there is no SRS resource indicator (i.e., srs-ResourceIndicator) in the corresponding configuration. Embodiments of this disclosure propose a technical solution to such a technical problem, particularly for CG type 1 PUSCH transmissions (e.g., PUSCH consisting only of RRC signaling).
[0047] Multiple SRS resource sets in a list, such as srs-ResourceSetToAddModList or srs-ResourceSetToAddModListDCI-0-2, with their usage set to "codebook" or "non-codebook," may be configured for M-TRP push transmissions. The UE supports simultaneous transmissions with multiple panels (i.e., STxMP), and multiple SRS resource sets in srs-ResourceSetToAddModList or srs-ResourceSetToAddModListDCI-0-2 with their usage set to "codebook" or "non-codebook" may also be configured for STxMP push transmissions, where the push transmission may be sent to one of multiple TRPs or two or more of multiple TRPs.
[0048] In this disclosure, two SRS resource sets, whose use is set to “codebook” or “non-codebook,” may be configured for push transmission, and the first of the two SRS resource sets may be an SRS resource set with a lower index (or lower identifier), and the second of the two SRS resource sets may be an SRS resource set with a higher index (or higher identifier). 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 push transmission. The first of the three SRS resource sets may have the lowest index, the second of the three SRS resource sets may have a higher index than the first SRS resource set, and the third SRS resource set may have the highest index. Other sets of SRS resources may be indexed in a similar manner.
[0049] In R17, M-TRP PUSCH transmission is supported based on legacy beam indication (i.e., spatial relation information), where the beam for PUSCH transmission is the same as the beam of the indicated SRS resource in the associated 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, where the Media Access Control Element (MAC CE) activates multiple Transmit Configuration Indication (TCI) code points, or the MAC CE activates only one TCI code point that is not related to the beam of the associated SRS resource. Furthermore, 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] If two SRS resource sets configured for a PUSCH transmission are configured to follow a common beam, then the beam of the associated SRS resource set for the PUSCH transmission and the beam of the PUSCH transmission are the same, and the PUSCH and the associated SRS resource sets for the PUSCH transmission are transmitted to the same TRP.
[0051] If two SRS resource sets configured for a push transmission are not configured to follow a common beam, the push transmission and its associated SRS resource sets should also be transmitted to the same TRP. Each SRS resource in each SRS resource set is configured by the RRC with the beam or activated by the MAC CE with the beam if the two SRS resource sets are not configured to follow a common beam. The beams of all SRS resources in one SRS resource set are associated with the same TRP, considering that they share the same power control parameter set. An association is established between the beam and the TRP to ensure that the push transmission and its associated SRS resource sets are transmitted to the same TRP.
[0052] In this disclosure, a TCI state group or TCI state pool (hereinafter, "TCI state group" and "TCI state pool" may be used interchangeably as appropriate) may be used to identify a TRP. Thus, two TCI state groups may be configured to identify two TRPs. Each beam is associated with one TCI state group by RRC signaling or MAC CE instruction. Thus, if a PUSCH transmission is associated with a beam associated with a TCI state group, the beam of the associated SRS resource set for the PUSCH transmission is also associated with a TCI state group. On the BS side, it may configure or activate a beam for one of two SRS resource sets configured for a PUSCH transmission so as to be associated with one of the two TCI state groups, and configure or activate a beam for the other SRS resource set configured for a PUSCH transmission so as to be associated with the other TCI state group of the two TCI state groups. In this disclosure, a beam may refer to a joint or UL TCI state.
[0053] Hereafter, in this disclosure, when a PUSCH transmit, such as a CG type 1 PUSCH transmit, is configured to be associated with two common beams, the PUSCH transmit iterations of a PUSCH transmit associated with one common beam (which may be time-division multiplexed, frequency-division multiplexed, or single-frequency networked), a layer subset of the PUSCH transmit (e.g., SDM), or a frequency portion of the PUSCH transmit (e.g., frequency-division multiplexed) will be referred to as PUSCH transmit opportunities. Accordingly, PUSCH transmit opportunities associated with a common beam are also associated with the same set of SRS resources as the two SRS resource sets.
[0054] Therefore, the common beam of a PUSCH transmission opportunity is always associated with the same TCI state group, and the beams of the associated SRS resource sets for a PUSCH transmission opportunity are associated regardless of whether the two SRS resource sets configured for PUSCH transmission are configured to follow the common beam shown for UL transmission.
[0055] According to some embodiments of this application, an indicator field (for example, referred to as an SRS resource set indicator or beam indicator) which may include two bits or other numbers of bits may be introduced and provided in a corresponding configuration to indicate a common beam and associated SRS resource set for a CG type 1 PUSCH, etc.
[0056] If only one SRS resource is configured for each of the two SRS resource sets configured for a PUSCH transmission, the srs-ResourceIndicator field does not exist in the corresponding configuration for the CG type 1 PUSCH transmission. In this case, the SRS resource set indicator or beam indicator is configured to show the beam and associated SRS resource sets for the PUSCH. If more than one SRS resource is configured for each SRS resource set, one or two srs-ResourceIndicator fields may be configured for the CG type 1 PUSCH transmission, etc. In this case, the number of srs-ResourceIndicators may indicate whether the PUSCH transmission is sent to a single TRP or to multiple TRPs. The SRS resource set indicator or beam indicator is not always required for the CG type 1 PUSCH transmission, etc. Two scenarios are shown separately below. The first scenario is that the srs-ResourceIndicator does not exist for the CG type 1 PUSCH, etc., and the SRS resource set indicator or beam indicator is always configured for the CG type 1 PUSCH transmission, etc. The second scenario is that at least one srs-ResourceIndicator field exists for CG type 1 PUSCH, etc., and an SRS resource indicator or beam indicator can optionally be configured for CG type 1 PUSCH, etc.
[0057] For example, Figure 2 shows a method of PUSCH according to several embodiments of the present disclosure, which can be performed by BS.
[0058] In operation 201, the BS may transmit configuration information indicating a CG type 1 PUSCH transmission, which includes at least one of the following to indicate which common beam of at least one common beam applicable to uplink transmissions in the slot is associated with the CG type 1 PUSCH transmission: first instruction information indicating the association of the CG type 1 PUSCH transmission with at least a portion of at least one common beam or with at least a portion of a set of SRS resources configured for the CG type 1 PUSCH transmission; second instruction information indicating the PUSCH scheme of the CG type 1 PUSCH transmission; or third instruction information including at most two SRS resource indicator values. In operation 202, the BS may receive a CG type 1 PUSCH transmission in the slot based on the configuration information.
[0059] Hereafter, using CG type 1 PUSCH transmission as an example, more specific embodiments will be shown in consideration of various scenarios. The PUSCH transmission may be a single TRP PUSCH transmission or a multi-TRP PUSCH transmission.
[0060] Scenario 1 In Scenario 1, the configuration for PUSCH transmission does not include SRS resource indicator information (e.g., srs-ResourceIndicator), or the SRS resource indicator information does not include an SRS resource indicator value, meaning that only one SRS resource is configured for each SRS resource set configured for PUSCH transmission. This disclosure proposes several strategies for determining one or more common beams for PUSCH transmission.
[0061] Policy 1-1A In this approach, at least one common beam and multiple SRS resource sets are configured for push transmission, and the network may configure first directional information indicating the association of a push transmission with at least some of the multiple SRS resource sets configured for push transmission. For example, the network may configure an SRS resource set indicator to indicate the relevant SRS resource set for push transmission.
[0062] The indicator information, i.e., the SRS resource set indicator, may contain one bit. Therefore, there are two states for the bit, namely "0" and "1", and the two states can indicate the following information, as shown in Table 1 below.
[0063] [Table 1]
[0064] In Table 1, the first state "0" indicates that the PUSCH transmission is associated with a first SRS resource set among several 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, if the SRS resource set configured for the PUSCH transmission is not configured to follow a common beam shown for the UL transmission, the beam of the first SRS resource set may be associated with a TCI state group, and within at least one common beam, there may be one common beam that is associated with the same TCI state group, and this common beam is determined to be 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.
[0065] In some other cases, if the SRS resource set configured for PUSCH transmission is configured to follow a common beam shown for UL transmission, the beam of the first SRS resource set may be the first common beam of at least one common beam, and this beam is determined to be 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 a PUSCH transmission is associated with at least two SRS resource sets from a plurality of SRS resource sets whose use is set to "Codebook" or "Non-Codebook". For each PUSCH transmission opportunity (or each opportunity for a PUSCH transmission), if the SRS resource set configured for the PUSCH transmission is not configured to follow a common beam shown for a UL transmission, then 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 a first PUSCH transmission opportunity, it may be associated with a first (or second, third, etc.) SRS resource set from a plurality of SRS resource sets whose use is set to "Codebook" or "Non-Codebook". The beam of the first SRS resource set may be associated with a TCI state group, and there may be at least one common beam that is similarly associated with the same TCI state group, and this common beam is determined to be the common beam for the first PUSCH transmission opportunity.
[0067] In some other cases, if the SRS resource set configured for PUSCH transmission is configured to follow a common beam shown for UL transmission, the beams of the first and second SRS resource sets may be the first and second common beams of at least one common beam, respectively, with the first common beam being 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 are the same.
[0068] In one embodiment, two common beams and two SRS resource sets are configured for PUSCH transmission, and the indicator information, for example, the SRS resource set indicator, may include one bit, so there are two states of the bit, for example, "0" and "1", and the two states may indicate the following information as shown in Table 2 below.
[0069] [Table 2]
[0070] In Table 2, the first state "0" indicates that the PUSCH transmission is associated with the first of two 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, if the SRS resource set configured for the PUSCH transmission is not configured to follow a common beam shown for the UL transmission, the beam of the first SRS resource set may be associated with a TCI state group, and there may be a common beam among the two common beams that is similarly associated with the same TCI state group, and this common beam is determined to be the common beam for the PUSCH transmission. In other words, the beam of the first SRS resource set and the common beam of the two common beams used for the PUSCH transmission are associated with the same TCI state group.
[0071] In some other cases, if the SRS resource set configured for PUSCH transmission is configured to follow a common beam shown 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 to be the common beam for PUSCH transmission. That is, the beam of the first SRS resource set and the common beam of the two common beams used for PUSCH transmission are the same.
[0072] In Table 2, the second state "1": A PUSCH transmission is associated with two SRS resource sets whose usage is set to "Codebook" or "Non-Codebook". A PUSCH transmission is associated with two SRS resource sets out of multiple SRS resource sets whose usage is set to "Codebook" or "Non-Codebook". For each PUSCH transmission opportunity (or each opportunity for a PUSCH transmission), if the SRS resource set configured for the PUSCH transmission is not configured to follow the common beam shown for the UL transmission, then 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 a first PUSCH transmission opportunity, it may be associated with the first (or second) SRS resource set out of multiple SRS resource sets whose usage is set to "Codebook" or "Non-Codebook". The beams of the first SRS resource set may be associated with TCI state groups, 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 to be the common beam for the first PUSCH transmission opportunity.
[0073] In some other cases, if the SRS resource set configured for PUSCH transmission is configured to follow a common beam shown for UL transmission, the beams of the first and second SRS resource sets may be the first and second common beams of two common beams, respectively, with the first common beam being 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 of the two common beams used for the first PUSCH transmission opportunity are the same.
[0074] The UE may determine the beam for PUSCH transmission in a manner similar to that described for Table 1, details of which are omitted here.
[0075] In some other embodiments, the indicator information, such as the SRS resource set indicator, may include 2 bits. There are four states of 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] In Table 3, the first state "00" indicates that a PUSCH transmission is associated with a first SRS resource set among several SRS resource sets whose use 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, if the SRS resource set configured for a PUSCH transmission is not configured to follow a common beam shown for a UL transmission, the beam of the first SRS resource set may be associated with a TCI state group, and there may be at least one common beam that is similarly associated with the same TCI state group, and this common beam is determined to be the common beam for the PUSCH transmission. In other words, the beam of the first SRS resource set and the common beam used for a PUSCH transmission of at least one common beam are associated with the same TCI state group.
[0078] In some other cases, if the SRS resource set configured for PUSCH transmission is configured to follow a common beam shown for UL transmission, the beam of the first SRS resource set may be the first common beam of at least one common beam, which is determined to be 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.
[0079] In Table 3, the second state "01" indicates that the PUSCH transmission is associated with a second SRS resource set among several SRS resource sets whose use is set to "Codebook" or "Non-Codebook". The UE may determine the beam for the PUSCH transmission based on the second SRS resource set. Specifically, if the SRS resource set configured for the PUSCH transmission is not configured to follow a common beam shown for the UL transmission, the beam of the second SRS resource set may be associated with a TCI state group, and there may be at least one common beam that is similarly associated with the same TCI state group, and this common beam is determined to be the common beam for the PUSCH transmission. In other words, the beam of the second 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.
[0080] In some other cases, if the SRS resource set configured for PUSCH transmission is configured to follow a common beam shown for UL transmission, the beam of the second SRS resource set may be the second common beam of at least one common beam, and this beam is determined to be 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 a PUSCH transmission is associated with at least two SRS resource sets out of a plurality of SRS resource sets whose usage is set to "Codebook" or "Non-Codebook". Of the PUSCH transmission opportunities, the first PUSCH transmission opportunity is associated with the first SRS resource set out of the plurality of SRS resource sets. For each PUSCH transmission opportunity (or each PUSCH transmission opportunity including the first PUSCH transmission opportunity), if the SRS resource set configured for the PUSCH transmission is not configured to follow a common beam shown for UL transmission, then 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 TCI state group, and there may be at least one common beam that is similarly associated with the same TCI state group, and this common beam is determined to be the common beam for the first PUSCH transmission opportunity.
[0082] In some other cases, if the SRS resource set configured for PUSCH transmission is configured to follow a common beam shown for UL transmission, the beams of the first SRS resource set and the second SRS resource set may be the first and second common beams of at least one common beam, respectively, with the first common beam being 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 are the same common beam of at least one common beam.
[0083] In some embodiments, the first PUSCH transmission opportunity may 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 indicates that a PUSCH transmission is associated with at least two SRS resource sets from a plurality of SRS resource sets whose usage is set to "Codebook" or "Non-Codebook". Of the PUSCH transmission opportunities, the first PUSCH transmission opportunity is associated with the second SRS resource set from the plurality of SRS resource sets. For each PUSCH transmission opportunity (or each PUSCH transmission opportunity including the first PUSCH transmission opportunity), if the SRS resource set configured for the PUSCH transmission is not configured to follow a common beam shown for UL transmission, then 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 TCI state group, and there may be at least one common beam that is similarly associated with the same TCI state group, and this common beam is determined to be the common beam for the first PUSCH transmission opportunity.
[0085] In some other cases, if the SRS resource set configured for PUSCH transmission is configured to follow a common beam shown for UL transmission, the beams of the first and second SRS resource sets may be the first and second common beams of at least one common beam, respectively, with the second common beam being 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 are the same common beam of at least one common beam.
[0086] In one embodiment, two common beams and two SRS resource sets are configured for PUSCH transmission, and the indicator information, i.e., the SRS resource indicator, may include 2 bits. There are four states of 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] In Table 4, the first state "00" indicates that the PUSCH transmission is associated with the first of two 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, if the SRS resource set configured for the PUSCH transmission is not configured to follow a common beam shown for the UL transmission, the beam of the first SRS resource set may be associated with a TCI state group, and there may be a common beam among the two common beams that is similarly associated with the same TCI state group, and this common beam is determined to be 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 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 a common beam shown 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 to be the common beam for PUSCH transmission. That is, the beam of the first SRS resource set and the common beam of the two common beams used for PUSCH transmission are the same.
[0090] In Table 4, the second state "01" indicates that the PUSCH transmission is associated with the second of two 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 second SRS resource set. Specifically, if the SRS resource set configured for the PUSCH transmission is not configured to follow the common beam shown for the UL transmission, the beam of the second SRS resource set may be associated with a TCI state group, and there may be a common beam among the two common beams that is similarly associated with the same TCI state group, and this common beam is determined to be the common beam for the PUSCH transmission. In other words, the beam of the second SRS resource set and the common beam used for the PUSCH transmission of the two common beams are associated with the same TCI state group.
[0091] In some other cases, if the SRS resource set configured for PUSCH transmission is configured to follow a common beam shown for UL transmission, the beam of the second SRS resource set may be the second common beam of 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 of the two common beams used for PUSCH transmission are the same.
[0092] The third state "10" in Table 4 indicates that a PUSCH transmission is associated with two SRS resource sets whose usage is set to "Codebook" or "Non-Codebook". Of the PUSCH transmission opportunities, the first PUSCH transmission opportunity is associated with the first of the two SRS resource sets. For each PUSCH transmission opportunity (or each PUSCH transmission opportunity including the first PUSCH transmission opportunity), if the SRS resource set configured for the PUSCH transmission is not configured to follow a common beam shown for UL transmission, then the beam of the SRS resource set associated with the PUSCH transmission opportunity and the common beam used for the two common beams of the PUSCH transmission opportunity are associated with the same TCI state group. For example, the beam of the first SRS resource set may be associated with a TCI state group, and there may be a common beam among the two common beams that is similarly associated with the same TCI state group, and this common beam is determined to be the common beam for the first PUSCH transmission opportunity.
[0093] In some other cases, if the SRS resource set configured for PUSCH transmission is configured to follow a common beam shown for UL transmission, the beams of the first and second SRS resource sets may be the first and second common beams of two common beams, respectively, with the first common beam being 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 of the two common beams used for the first PUSCH transmission opportunity are the same.
[0094] The fourth state "11" in Table 4 indicates that a PUSCH transmission is associated with two SRS resource sets whose usage is set to "Codebook" or "Non-Codebook". Of the PUSCH transmission opportunities, the first PUSCH transmission opportunity is associated with the second of the two SRS resource sets. For each PUSCH transmission opportunity (or each PUSCH transmission opportunity including the first PUSCH transmission opportunity), if the SRS resource set configured for the PUSCH transmission is not configured to follow a common beam shown for UL transmission, then the beam of the SRS resource set associated with the PUSCH transmission opportunity and the common beam used for the two common beams of the PUSCH transmission opportunity are associated with the same TCI state group. For example, the beam of the second SRS resource set may be associated with a TCI state group, and there may be a common beam among the two common beams that is similarly associated with the same TCI state group, and this common beam is determined to be the common beam for the first PUSCH transmission opportunity.
[0095] In some other cases, if the SRS resource set configured for a push transmission is configured to follow a common beam shown for a ul transmission, the beams of the first and second SRS resource sets may be the first and second common beams of two common beams, respectively, with the second common beam being determined as the common beam for the first push transmission opportunity. That is, the beam of the second SRS resource set and the common beam used for the first push transmission opportunity of the two common beams are the same.
[0096] Policy 1-1B In this approach, at least one common beam and multiple SRS resource sets are configured for push transmission, and the network may configure indicator information that shows the association of a push transmission with at least one of the common beams configured for push transmission. For example, the network may configure a beam indicator to indicate the relevant beam for push transmission. Note that the network may configure either an SRS resource set indicator or a beam indicator.
[0097] The indicator information, or beam indicator, may contain one bit. The bit has two states, namely "0" and "1", and the two states can represent the following information as shown in Table 5 below.
[0098] [Table 5]
[0099] In Table 5, the first state "0" indicates that the PUSCH transmission is associated with the first common beam of at least one common beam. The UE may determine an SRS resource set from among multiple SRS resource sets based on the first common beam. Specifically, if the SRS resource set configured for the PUSCH transmission is not configured to follow the common beam shown for the UL transmission, the first common beam may be associated with a TCI state group, and there may be an SRS resource set from among multiple 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 beam of the SRS resource set associated with the PUSCH transmission from among multiple SRS resource sets are associated with the same TCI state group.
[0100] In some other cases, if the SRS resource set configured for PUSCH transmission is configured to follow a common beam shown for UL transmission, the first common beam and the beam of one of the SRS resource sets among the multiple 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 multiple SRS resource sets are configured for the PUSCH transmission.
[0102] The UE may determine the SRS resource set of multiple SRS resource sets based on at least two common beams.
[0103] For each PUSCH transmission opportunity (or each PUSCH transmission opportunity), if the SRS resource set configured for the PUSCH transmission is not configured to follow a common beam indicated for the UL transmission, then the beam of the SRS resource set associated with the PUSCH transmission of at least two common beams and the beam of the SRS resource set associated with the PUSCH transmission of the multiple SRS resource sets are associated with the same TCI state group. For example, for a first PUSCH transmission opportunity, it may be associated with the first (or second, third, etc.) common beam of at least two common beams, and the first common beam is associated with the TCI state group. Among the multiple 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.
[0104] In some other cases, if the SRS resource set configured for a push transmission is configured to follow a common beam shown for a ul transmission, the first (or second, third, etc.) common beam and the beam of one of the SRS resource sets among the multiple SRS resource sets may be the same, and the push transmission is associated with this SRS resource set.
[0105] In one embodiment, two common beams and two SRS resource sets are configured for PUSCH transmission, and the indicator information, i.e., the beam indicator, may include one bit. The bit has two states, i.e., "0" and "1", and the two states may indicate the following information as shown in Table 6 below.
[0106] [Table 6]
[0107] In Table 6, the first state "0" indicates that the PUSCH transmission is associated with the first common beam of the two common beams. The UE may determine the SRS resource set of the two SRS resource sets based on the first common beam. Specifically, if the SRS resource set configured for the PUSCH transmission is not configured to follow the common beam shown for the 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 beam of the SRS resource set associated with the PUSCH transmission of the two SRS resource sets are associated with the same TCI state group.
[0108] In some other cases, if the SRS resource set configured for PUSCH transmission is configured to follow a common beam shown for UL transmission, the first common beam and the beam of 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 can determine which of the two SRS resource sets to use based on the two common beams.
[0110] For each PUSCH transmission opportunity (or each PUSCH transmission opportunity), if the SRS resource set configured for the PUSCH transmission is not configured to follow a common beam indicated for the UL transmission, then the common beam of the two common beams and the beam of the SRS resource set associated with the PUSCH transmission of the two SRS resource sets are associated with the same TCI state group. For example, for a 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 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.
[0111] In some other cases, if the SRS resource set configured for PUSCH transmission is configured to follow a common beam shown for UL transmission, the first (or second) common beam and the beam of 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 indicator information, i.e., the beam indicator, may include 2 bits. There are four states of 2 bits, namely "00", "01", "10", and "11", and the four states may represent the following information as shown in Table 7 below.
[0113] [Table 7]
[0114] In Table 7, the first state "00" indicates that the PUSCH transmission is associated with the first common beam of at least one common beam. The UE may determine the SRS resource set from among multiple SRS resource sets based on the first common beam in a similar manner to the first state "0" in Table 5, details of which 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] In Table 7, the second state "01" indicates that the PUSCH transmission is associated with the second common beam of at least two common beams. The UE may determine the SRS resource set from among multiple SRS resource sets based on the second common beam.
[0117] The third state "10" in Table 7 indicates that a PUSCH transmission is associated with at least two common beams. Of the PUSCH transmission opportunities, the first PUSCH transmission opportunity is associated with the first common beam.
[0118] For each PUSCH transmission opportunity (or each PUSCH transmission opportunity including the first PUSCH transmission opportunity), if the SRS resource set configured for the PUSCH transmission is not configured to follow a common beam shown for the UL transmission, then the beam of the SRS resource set associated with the PUSCH transmission of the multiple 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 of the at least two common beams, and the first common beam is associated with the TCI state group. Among the multiple 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.
[0119] In some other cases, if the SRS resource set configured for PUSCH transmission is configured to follow a common beam shown for UL transmission, the first (or second, third, etc.) common beam and the beam of one of the SRS resource sets among the multiple 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 a PUSCH transmission is associated with at least two common beams. Of the PUSCH transmission opportunities, the first PUSCH transmission opportunity is associated with the second common beam.
[0121] For each PUSCH transmission opportunity (or each PUSCH transmission opportunity including the first PUSCH transmission opportunity), if the SRS resource set configured for the PUSCH transmission is not configured to follow a common beam shown for the UL transmission, then the beam of the SRS resource set associated with the PUSCH transmission of the multiple 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 of the at least two common beams, and the first common beam is associated with the TCI state group. Among the multiple 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.
[0122] In some other cases, if the SRS resource set configured for PUSCH transmission is configured to follow a common beam shown for UL transmission, the first (or second, third, etc.) common beam and the beam of one of the SRS resource sets among the multiple SRS resource sets may be the same beam, and the PUSCH transmission is associated with this SRS resource set.
[0123] In one embodiment, two common beams and two SRS resource sets are configured for PUSCH transmission, and the indicator information, i.e., the beam indicator, may include 2 bits. There are four states of 2 bits, namely "00", "01", "10", and "11", and the four states may represent the following information as shown in Table 8 below.
[0124] [Table 8]
[0125] In Table 8, the first state "00" indicates that the PUSCH transmission is associated with the first common beam of the two common beams. The UE may determine the SRS resource set of the two SRS resource sets based on the first common beam in a similar manner to the first state "0" in Table 5, details of which 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] In Table 8, the second state "01" indicates that the PUSCH transmission is associated with the second common beam of at least two common beams. The UE may determine which of the two SRS resource sets is based on the second common beam.
[0128] The third state "10" in Table 8 indicates that the PUSCH transmission is associated with two common beams. Of the PUSCH transmission opportunities, the first PUSCH transmission opportunity is associated with the first common beam.
[0129] For each PUSCH transmission opportunity (or each PUSCH transmission opportunity including the first PUSCH transmission opportunity), if the SRS resource set configured for the PUSCH transmission is not configured to follow a common beam shown for the UL transmission, then the common beam of the two common beams and the beam of the SRS resource set associated with 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 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.
[0130] In some other cases, if the SRS resource set configured for PUSCH transmission is configured to follow a common beam shown for UL transmission, the first (or second) common beam and the beam of 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. Of the PUSCH transmission opportunities, the first PUSCH transmission opportunity is associated with the second common beam.
[0132] For each PUSCH transmission opportunity (or each PUSCH transmission opportunity including the first PUSCH transmission opportunity), if the SRS resource set configured for the PUSCH transmission is not configured to follow a common beam shown for the UL transmission, then the common beam of the two common beams and the beam of the SRS resource set associated with 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 of the 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.
[0133] In some other cases, if the SRS resource set configured for a push transmission is configured to follow a common beam shown for a ul transmission, the first (or second) common beam and the beam of one of the two SRS resource sets may be the same beam, and the push transmission is associated with this SRS resource set.
[0134] Scenario 2 In this scenario, the configuration of the PUSCH transmission does not include SRS resource indication information (e.g., srs-ResourceIndicator), or the SRS resource indication information does not include any SRS resource indicator values, meaning that only one SRS resource is configured for each SRS resource set configured for the PUSCH transmission. The UE may receive second indication information indicating the PUSCH scheme of the PUSCH transmission, which 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 consists of at least two iterations. - PUSCH transmission is configured using frequency division multiplexing (FDM) A, FDM B, or single frequency network (SFN) scheme. - The PUSCH transmission is indicated using at least two demodulation reference signal (DMRS) ports from two different CDM groups.
[0135] In other words, the second instruction information indicates that there are multiple PUSCH transmission opportunities for transmission. For each PUSCH transmission opportunity, if the SRS resource set configured for the PUSCH transmission is not configured to follow a common beam indicated for UL transmission, then that common beam of at least two common beams and the beam of the SRS resource set associated with the PUSCH transmission of at least two SRS resource sets are associated with the same TCI state group. For example, for a first PUSCH transmission opportunity, it may be associated with the first (or second, or third, etc.) common beam of at least two common beams, and the first common beam is associated with the TCI state group. Among the at least 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 an SRS resource set configured for PUSCH transmission is configured to follow a common beam shown for UL transmission, then the common beam of at least two common beams and the beams of the SRS resource sets associated with PUSCH transmission for at least two SRS resource sets are the same beam.
[0136] In one embodiment, a 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 the PUSCH transmission is not configured to follow the common beam shown for the UL transmission, then the beam of that common beam and the beam of the SRS resource set associated with the PUSCH transmission of the two SRS resource sets are associated with the same TCI state group. For example, for a first PUSCH transmission opportunity, it may be associated with the first (or second) common beam of at least two common beams, the first common beam being 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. Thus, this SRS resource set is associated with the PUSCH transmission opportunity. Alternatively, if an SRS resource set configured for PUSCH transmission is configured to follow a common beam shown for UL transmission, then the common beam of 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 instruction information, the PUSCH transmission is transmitted using the first common beam of at least two common beams and associated with one of at least two SRS resource sets, and if 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 SRS resource set and the common beam 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 the UL transmission, the beam of the SRS resource set is the first common beam.
[0138] Scenario 3 In Scenario 3, the configuration for a PUSCH transmission does not include SRS resource indicator information (e.g., srs-ResourceIndicator), or the SRS resource indicator information does not include any SRS resource indicator values, meaning that only one SRS resource is configured for each SRS resource set for a PUSCH transmission. The PUSCH transmission is configured to be associated with one common beam, regardless of how many common beams are indicated for a UL transmission. In some cases, only one common beam is indicated for a 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 a UL transmission, and the PUSCH transmission is associated with the first of the two or more common beams. A PUSCH transmission may be configured to be associated with multiple SRS resource sets, among which there may be an SRS resource set whose beam and one common beam (or first common beam) are associated with the same TCI group if the SRS resource set configured for the PUSCH transmission is not configured to follow a common beam shown for the UL transmission, or if the SRS resource set configured for the PUSCH transmission is configured to follow a common beam shown for the UL transmission, then the beam and one common beam (or first common beam) of that SRS resource set are the same.
[0139] For all of the above scenarios, if only one common beam is indicated for UL transmission, the PUSCH transmission will fall back to a single TRP PUSCH transmission regardless of the configuration information. The PUSCH transmission is associated with a common beam. The PUSCH transmission is associated with one of several SRS resource sets, and the beam of that SRS resource set and the one common beam are the same if the SRS resource set configured for PUSCH transmission is not configured to follow the common beam indicated for UL transmission, or if the SRS resource set configured for PUSCH transmission is configured to follow the common beam indicated for UL transmission, then the beam of that SRS resource set and the one common beam are the same.
[0140] Scenario 4 In this scenario, the UE may receive third directive information indicating one or more SRS resource indicator values. For example, the third directive information may include one or two SRS resource indicators, e.g., srs-ResourceIndicator. The number of common beams associated with a PUSCH transmission may also be indicated by the third directive information; for example, one srs-ResourceIndicator may indicate that a PUSCH transmission can be associated with only one common beam. Two srs-ResourceIndicators may indicate that a PUSCH transmission can be associated with one or two common beams.
[0141] Case 1:
[0142] In this example, the UE does not receive the first instruction information, i.e., the SRS resource set indicator or beam indicator, and instead receives third instruction information, which may contain zero, one, or two srs-ResourceIndicators. If the third instruction information contains zero srs-ResourceIndicators, the third instruction information may be omitted, and therefore this example is omitted here.
[0143] Case 1-1:
[0144] If the third instruction information indicates one SRS resource indicator value, i.e., one srs-ResourceIndicator is configured, then a PUSCH transmission may be associated with only one common beam. If two common beams are indicated for a UL transmission, then a PUSCH transmission may be transmitted by the first of the two common beams. If only one common beam is indicated, then a PUSCH transmission may be transmitted by that single common beam. With respect to an SRS resource set, the beam of the SRS resource set associated with a PUSCH transmission and its one common beam (or the first of two common beams) are associated with the same TCI state group if the SRS resource set configured for a PUSCH transmission is not configured to follow a common beam indicated for a UL transmission, or if the SRS resource set configured for a PUSCH transmission is configured to follow a common beam indicated for a UL transmission, then the beam of the SRS resource set associated with a PUSCH transmission and its one common beam (or the first of two common beams) are the same beam. Furthermore, the indicator, namely srs-ResourceIndicator, is associated with an SRS resource set.
[0145] Case 1-2:
[0146] If the third instruction information indicates two SRS resource indicator values, i.e., two indicators, i.e., an srs-ResourceIndicator is configured, then a PUSCH transmission may be associated with two common beams according to the indicated common beam for a UL transmission. The first indicator, i.e., the first srs-ResourceIndicator, may be associated with a first SRS resource set, and the second indicator, i.e., the second srs-ResourceIndicator, may be associated with a second SRS resource set.
[0147] If two common beams are also indicated for UL transmission, a PUSCH transmission may be associated with those two common beams. For each PUSCH transmission opportunity, the beams 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 unless the SRS resource set configured for PUSCH transmission is configured to follow a common beam indicated for UL transmission. Alternatively, the beams 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 a common beam indicated for UL transmission.
[0148] A first PUSCH transmission opportunity may be associated with a first common beam, or it may be associated with a first SRS resource set (which may be indicated by a first srs-ResourceIndicator). In some embodiments, a 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, a PUSCH transmission may be associated with that single common beam. The beam of the SRS resource set associated with a PUSCH transmission and its single common beam are associated with the same TCI state group if the SRS resource set configured for the PUSCH transmission is not configured to follow the common beam indicated for UL transmission, or the beam of the SRS resource set associated with a PUSCH transmission and its single common beam are the same if the SRS resource set configured for the PUSCH transmission is configured to follow the common beam indicated for UL transmission. A PUSCH transmission is associated with one indicator (i.e., srs-ResourceIndicator) associated with the SRS resource set.
[0150] Case 2:
[0151] In this case, the UE receives not only the first instruction information, i.e., the SRS resource set indicator or beam indicator, but also the third instruction information, which may include zero, one, or two srs-ResourceIndicators. If the third instruction information includes zero srs-ResourceIndicators, the third instruction information may be omitted, and therefore the UE may determine the common beam for PUSCH transmission based solely on the first instruction information.
[0152] Case Study 2-1
[0153] If the third instruction information indicates a single SRS resource indicator value, i.e., if a single srs-ResourceIndicator is configured, then the first instruction information may indicate only a state associated with a single SRS resource set. For example, only the state of the SRS resource set indicator indicating that a PUSCH transmission is associated with a single SRS resource set may be configured for a PUSCH transmission, or only the state of the beam indicator indicating that a PUSCH transmission is associated with a single beam may be configured for a PUSCH transmission.
[0154] If only one common beam is indicated for UL transmission, a PUSCH transmission may be associated with that single common beam. The beam of the SRS resource set associated with a PUSCH transmission and its single common beam are associated with the same TCI state group if the SRS resource set configured for the PUSCH transmission is not configured to follow the common beam indicated for UL transmission, or the beam of the SRS resource set associated with the PUSCH transmission and its single common beam are the same if the SRS resource set configured for the PUSCH transmission is configured to follow the common beam indicated for UL transmission. A PUSCH transmission is associated with an indicator (i.e., srs-ResourceIndicator).
[0155] If two common beams are indicated for UL transmission, a PUSCH transmission may be transmitted by one of the two common beams according to the first instruction. With respect to the SRS resource set associated with a PUSCH transmission, the beam of the SRS resource set associated with the PUSCH transmission and one of its common beams (or the first of the two common beams) are associated with the same TCI state group if the SRS resource set configured for the PUSCH transmission is not configured to follow the common beam indicated for UL transmission, or the beam of the SRS resource set associated with the PUSCH transmission and one of its common beams (or the first of the two common beams) are the same beam if the SRS resource set configured for the PUSCH transmission is configured to follow the common beam indicated for UL transmission. Furthermore, an indicator, namely the srs-ResourceIndicator, is associated with the SRS resource set associated with a PUSCH transmission.
[0156] Case Study 2-2
[0157] If the third instruction information indicates two SRS resource indicator values, i.e., two indicators, i.e., srs-ResourceIndicators, then the first instruction information may indicate any state associated with one or two SRS resource sets. The first indicator (first srs-ResourceIndicator) and the second indicator (second srs-ResourceIndicator) may be associated with a first SRS resource set and a second SRS resource set, respectively. For example, a state of an SRS resource set indicator indicating that a PUSCH transmission is associated with one or two SRS resource sets may be configured for a PUSCH transmission, and a state of a beam indicator indicating that a PUSCH transmission is associated with one or two beams may be configured for a PUSCH transmission.
[0158] If only one common beam is indicated for UL transmission, a PUSCH transmission may be associated with that single common beam. The beam of the SRS resource set associated with a PUSCH transmission and its single common beam are associated with the same TCI state group if the SRS resource set configured for the PUSCH transmission is not configured to follow the common beam indicated for UL transmission, or the beam of the SRS resource set associated with the PUSCH transmission and its single common beam are the same if the SRS resource set configured for the PUSCH transmission is configured to follow the common beam indicated for UL transmission. A PUSCH transmission is associated with one indicator (i.e., srs-ResourceIndicator) associated with the SRS resource set.
[0159] If two common beams are indicated for UL transmission, the 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] If a PUSCH transmission is associated with only one SRS resource set according to the first configuration information, the PUSCH transmission will be 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, will not be used.
[0161] Figure 3 illustrates how a CG type 1 push transmission is performed by a UE according to some embodiments of the present disclosure.
[0162] In operation 301, the UE may receive configuration information indicating a CG type 1 PUSCH transmission, which includes at least one of the following to indicate which common beam of the at least one common beam applicable to uplink transmissions in the slot is associated with the CG type 1 PUSCH transmission: first directional information indicating the association of the CG type 1 PUSCH transmission with at least a portion of at least one common beam or with at least a portion of a plurality of SRS resource sets configured for a CG type 1 PUSCH transmission (e.g., an SRS resource set indicator or beam indicator, as described in Scenario 1); second directional information indicating the PUSCH scheme of the CG type 1 PUSCH transmission (e.g., second directional information, as described in Scenario 2); or third directional information including at most two SRS resource indicator values (e.g., third directional information, as described in Scenario 4).
[0163] In some embodiments, the configuration information includes at least a first instruction information and a third instruction information that does not include SRS resource indicator values, and if at least two common beams are applicable to uplink transmissions in a slot, the CG type 1 PUSCH transmission is associated with one or more common beams from the at least two common beams and one or more SRS resource sets from a plurality of SRS resource sets, according to the first instruction information. For example, the UE may receive an SRS resource set indicator or a beam indicator and not receive the third information.
[0164] In some embodiments, the configuration information includes at least a first instruction information and a third instruction information including one SRS resource indicator value, and if at least two common beams are applicable to uplink transmissions in a slot, the CG type 1 PUSCH transmission is associated with one common beam out of the at least two common beams and one SRS resource set out of a plurality of SRS resource sets, according to the first and third instruction information. For example, the UE may receive an SRS resource set indicator or beam indicator and one SRS resource indicator, such as an srs-ResourceIndicator as described in Example 2-1 of Scenario 4.
[0165] In some embodiments, the configuration information includes at least a first instruction information and a third instruction information including two SRS resource indicator values, and when two common beams are applicable to uplink transmissions in a slot, the CG type 1 PUSCH transmission is associated with one or more common beams from the two common beams and one or more SRS resource sets from a plurality of SRS resource sets, according to the first instruction information. For example, the UE may receive an SRS resource set indicator or beam indicator and two SRS resource indicators, such as the srs-ResourceIndicator described in Example 2-2 of Scenario 4.
[0166] In some embodiments, the first instruction information relates a CG type 1 PUSCH transmission to at least a portion of a plurality of SRS resource sets, wherein the CG type 1 PUSCH transmission is associated with a first SRS resource set among the plurality of SRS resource sets, wherein the beam of the first SRS resource set and the common beam used for the CG type 1 PUSCH transmission of at least one common beam are associated with the same TCI state group, or the beam of the first SRS resource set is the same as the common beam used for the CG type 1 PUSCH transmission of at least one common beam (for example, bit state "0" in table 1 or bit state "00" in table 3), or the CG type 1 PUSCH transmission is associated with a second SRS resource set among the plurality of SRS resource sets, wherein the beam of the second SRS resource set and the common beam used for the CG type 1 PUSCH transmission of at least one common beam are associated with the same TCI state group, or the beam of the second SRS resource set is the same as the common beam used for the CG type 1 PUSCH transmission of at least one common beam The common beam used for the PUSCH transmission is the same as the common beam used for the PUSCH transmission (for example, bit state "01" in Table 3), associated with the same common beam, and the CG type 1 PUSCH transmission is associated with at least two SRS resource sets out of a plurality of SRS resource sets, wherein the first opportunity of the CG type 1 PUSCH transmission is associated with the first SRS resource set, and for each opportunity of the CG type 1 PUSCH transmission, the beam of the SRS resource set associated with the opportunity and the common beam used for the opportunity of at least one common beam are associated with the same TCI state group, or the beam of the SRS resource set associated with the opportunity is the same as the common beam used for the opportunity of at least one common beam (for example, bit state "10" in Table 3), associated with the same common beam, or CG type 1A PUSCH transmission is associated with at least two SRS resource sets out of a plurality of SRS resource sets, and is shown by indicating that for each opportunity of a CG type 1 PUSCH transmission, the beam of the SRS resource set associated with the opportunity and the common beam used for the opportunity of at least one common beam are associated with the same TCI state group, or the beam of the SRS resource set associated with the opportunity is the same as the common beam used for the opportunity of at least one common beam (for example, bit state "11" in Table 3).
[0167] In some embodiments, the first instruction information relates a CG type 1 PUSCH transmission to at least a portion of at least one common beam, wherein the CG type 1 PUSCH transmission is associated with a first common beam of at least one common beam, wherein the first common beam and the beams of the SRS resource sets associated with the CG type 1 PUSCH transmission of multiple SRS resource sets are associated with the same TCI state group, or the beams of the SRS resource sets associated with the CG type 1 PUSCH transmission of multiple SRS resource sets are the same as the first common beam (for example, bit state "0" in table 5 or bit state "00" in table 7), or the CG type 1 PUSCH transmission is associated with a second common beam of at least one common beam, wherein the second common beam and the beams of the SRS resource sets associated with the CG type 1 PUSCH transmission of multiple SRS resource sets are associated with the same TCI state group, or the beams of the SRS resource sets associated with the CG type 1 PUSCH transmission of multiple SRS resource sets are the same as the first common beam. The beam of the SRS resource set associated with a PUSCH transmission is the same as the second common beam (for example, bit state "01" in Table 7), associated with the CG type 1 PUSCH transmission, and the first opportunity of a CG type 1 PUSCH transmission is associated with the first common beam of the at least two common beams, and for each opportunity of a CG type 1 PUSCH transmission, the beam of the SRS resource set associated with the opportunity and the common beam used for the opportunity of at least two common beams are associated with the same TCI state group, or the beam of the SRS resource set associated with an opportunity of multiple SRS resource sets is the same as the common beam used for the opportunity of at least two common beams (for example, bit state "10This is indicated by showing that the first opportunity for a PUSCH transmission is associated with the second common beam of at least two common beams, and for each opportunity for a CG type 1 PUSCH transmission, the beam of the SRS resource set associated with the opportunity and the common beam used for the opportunity of at least two common beams are associated with the same TCI state group, or the beam of the SRS resource set associated with the opportunity of multiple SRS resource sets is the same as the common beam used for the opportunity of at least two common beams (bit state "11" in Table 7), which is one of the associations.
[0168] In some embodiments, when only one common beam is applicable to uplink transmissions in a slot, a CG type 1 PUSCH transmission is associated with one common beam and one SRS resource set out of multiple SRS resource sets, and the beam of the SRS resource set and its one common beam are associated with the same TCI state group, or the beam of that SRS resource set out of multiple SRS resource sets is the same as its one common beam. That is, when only one common beam is indicated for UL transmission, the PUSCH transmission falls back to a single TRP PUSCH transmission regardless of the configuration information.
