[0030] 3GPP TS describes operations that rely on the Transmit Configuration Indicator (TCI) state to facilitate communication. The TCI state may define a quasi-co-location (QCL) relationship between a source and a target. The source and target may be reference signals, such as, for example, a synchronization signal block (SSB), a channel state information-reference signal (CSI-RS) (for beam management or channel quality indicator (CQI) measurement), a sounding reference signal (SRS), or a demodulation reference signal (DMRS). Channel properties (e.g., spatial, time, or frequency domain properties) determined for the source may be inferred relative to the target. Different QCL type indications may infer different channel properties. For example, QCL type A corresponds to Doppler shift, Doppler spread, average delay, and delay spread; QCL type B corresponds to Doppler shift and Doppler spread; QCL type C corresponds to Doppler shift and average delay; and QCL type D corresponds to spatial Rx parameters.

[0031] 3GPP Release 17 (R17) introduced a unified TCI framework for single TRP operation. A unified TCI state may refer to a TCI state applied to multiple downlink channels or uplink channels. For example, a unified downlink (DL) TCI state may be applied to both a downlink data channel (e.g., physical downlink shared channel (PDSCH)) and a downlink control channel (e.g., physical downlink control channel (PDCCH)), while a unified uplink (UL) TCI state may be applied to both an uplink data channel (e.g., PUSCH) and an uplink control channel (e.g., PUCCH). The R17 unified TCI state supports two modes. In the first mode, a joint unified TCI state applies to both uplink and downlink channels. In the second mode, a DLTCI state is used for a downlink channel, and an independent UL TCI state is used for an uplink channel.

[0032] To support both modes of R17, RRC signaling can be used to configure the UE with a unified TCI state pool by signaling one or two lists. If only one list is used to configure the pool, the list will be the DL or joint TCI state list (dl-OrJoint-TCIStateList) with the TCI state to be used as the joint unified TCI state. If two lists are used to configure the pool, the first list (dl-OrJoint-TCIStateList) will provide the unified DL TCI state, and the second list (ul-TCI-StateList) will provide the unified UL TCI state.

[0033] In the Release 17 unified TCI framework, the TCI state of a configured pool can be indicated / activated in one of two ways. In the first way, a MAC control element (CE) is used to indicate the joint unified TCI state of the configured pool, or to indicate one unified DL TCI state and one unified DL TCI state. In the second way, a MAC CE can activate multiple joint unified TCI states or multiple unified UL / DL TCI state sets. Subsequently, DCI can be used to indicate one of the activated TCI / TCI sets to be used.

[0034] The R17 unified TCI framework is designed to support scenarios where all uplink and downlink signals / channels are received / transmitted using the same beam (e.g., TCI state). The R17 unified TCI framework also provides support for scenarios where all downlink signals are received in one beam and all uplink signals are transmitted in one beam. These limitations of the R17 unified TCI framework inhibit support for multi-TRP (mTRP) operation.

[0035] The embodiments address various issues that may occur when extending the unified TCI framework from single TRP (sTRP) to mTRP. Some embodiments describe how to associate the indicated TCI state with a semi-persistent scheduling (SPS) PDSCH. These embodiments may describe the UE behavior when the unified TCI state is updated from two to one for different mTRP schemes including spatial division multiplexing (SDM), frequency division multiplexing (FDM) (both Scheme A and Scheme B), and time division multiplexing (TDM) (both Scheme A and Scheme B). Additional embodiments describe how to indicate the unified TCI state for type 1 and type 2 configuration grant (CG) PUSCH. Some aspects of these embodiments may define the UE behavior when the TCI state is updated from two to one for different mTRP schemes, such as, for example, simultaneous transmission (STxMP) and repeated switching (as introduced in R17) by multiple panels. Still other embodiments describe how to determine the TCI state for a CG or dynamic grant (DG) PUSCH scheduled by a fallback DCI 1_0 without an indicator field.

[0036] Figure 1 A network environment 100 according to some embodiments is illustrated. The network environment 100 may include a UE 104 and a base station 108. The base station 108 may be coupled to multiple TRPs 112 to provide one or more wireless access cells through which the UE 104 can communicate. As shown, the base station 108 may be coupled to two TRPs 112 (e.g., TRP 1 and TRP 2). The base station 108 may use the TRPs 112 to provide geographically distributed transmit / receive points to increase cell coverage and spatial diversity. Each of the TRPs may include a single TRP or a group of TRPs that are generally controlled as a single TRP.

[0037] Although Figure 1 The base station 108 is illustrated as being directly coupled to two TRPs, but in other embodiments, more than one base station can be coupled to two TRPs, and the base stations can communicate with each other over backhaul links to coordinate communications with the UE 104. The base stations 108 and TRPs 112 can be collectively referred to as access nodes 116.

[0038] The access node 116 may provide an air interface compatible with 3GPP technical specifications, such as those defining fifth generation (5G) New Radio (NR) or higher system standards. Depending on the technology, the base station 108 may be referred to as an eNB, gNB, ng-NB, etc. The access node 116 may provide the UE 104 with access to other networks (e.g., a core network, a data network, etc.).

[0039] The access node 116 may control uplink and downlink operations through the physical (PHY) layer and the medium access control (MAC) layer.Configuration information may be provided to the UE 104 by the RRC layer.

[0040] In some embodiments, access node 116 may perform single-DCI mTRP operation in which a single DCI is used to schedule uplink or downlink transmissions for more than one TRP. For example, as shown, TRP 1 may transmit a DCI to UE 104 that schedules uplink / downlink channel transmissions for both TRP 1 and TRP 2.

[0041] Embodiments of the present disclosure describe aspects of two unified TCI states activated / indicated for single DCI mTRP operation for uplink / downlink transmissions, including SPS-PDSCH transmissions, CG-PUSCH transmissions (type 1 and type 2), DG-PU SCH transmissions, and PUSCH transmissions with fallback DCI scheduling.

[0042] Figure 2 TCI configuration and signaling aspects according to some embodiments are illustrated.

[0043] In some embodiments, configuration signaling may be used to configure the TCI state pool 200. The configuration signaling may include RRC signaling that provides two TCI state lists (e.g., dl-OrJoint-TCIStateList and ul-TCIStat eList). The TCI states from the dl-OrJoint-TCIStateList may provide the DL TCI states of the TCI state pool 200, and the TCI states from the ul-TCIStateList may provide the UL TCI states of the TCI state pool 200. Indicator signaling may then be used to associate one or two TCI states from the TCI state pool 200 with an UL channel or a DL channel. For example, as shown, the indicator signaling may provide a first association 204 that associates two DL TCI states with a DL channel. The indicator signaling may also be used to provide a second association 208 that associates two UL TCI states with an UL channel. The indicator signaling may be MAC-CE-based indicator signaling or MAC-CE+DCI-based indicator signaling.

[0044] In some embodiments, configuration signaling may be used to configure the TCI state pool 212. The configuration signaling may include RRC signaling that provides a TCI state list (e.g., dl-OrJoint-TCIStateList). The TCI states from the dl-OrJoint-TCIStateList may provide joint (JT) TCI states for the TCI state pool 212. Indicator signaling may then be used to associate one or two TCI states from the TCI state pool 212 with an UL channel or a DL channel. For example, as shown, the indicator signaling may provide a first association 216 that associates two JT TCI states with a DL channel. The indicator signaling may also be used to provide a second association 220 that associates two JT TCI states with an UL channel. The indicator signaling may be MAC-CE-based indicator signaling or MAC-CE+DCI-based indicator signaling.

[0045] Two TCI states can be associated with a channel to facilitate mTRP operation. For example, a first TCI state can be used for communications to / from a first TRP, while a second TCI state can be used for communications to / from a second TRP.

[0046] In some embodiments, two unified TCI states may be associated with the SPS PDSCH. The two unified TCI states may include a unified DL TCI state or a joint unified TCI state. The UE 104 may determine how to receive the SPS-PDSCH transmission using the two unified TCI states according to one or more of the following options.

[0047] In a first option, a mode indicator may be added to the SPS configuration information element (IE) that configures resources for the SPS PDSCH. The mode indicator may be a two-bit indicator that indicates the operating mode of the UE 104. The operating mode may be a first operating mode in which the UE 104 receives SPS PDSCH transmissions using a first TCI state of two unified TCI states; a second operating mode in which the UE receives SPS PDSCH transmissions using a second TCI state of two unified TCI states; or a third operating mode in which the UE 104 receives SPS PDSCH transmissions using both the first TCI state and the second TCI state. In the third operating mode, the SPS PDSCH may be configured for spatial repetition, time repetition, or frequency repetition, in which case the first TCI state is used for the first repetition and the second TCI state is used for the second repetition. The pattern may be repeated for subsequent repetitions. As used herein, repetition may refer to a transmission that will be sent more than once. Thus, a first transmission instance may be referred to as a repetition even if it has not yet been repeated at the time of transmission.

[0048] The first two operating modes may be referred to as sTRP operating modes, and the third operating mode may be referred to as mTRP operating mode. In some embodiments, another mTRP operating mode may be signaled by a two-bit indicator in which the order in which the TCI states are used is reversed. For example, in the fourth operating mode, the UE 104 may receive a first repetition of an SPS PDSCH transmission using the second TCI state and a second repetition of an SPS PDSCH transmission using the first TCI state. This pattern may be repeated for subsequent repetitions.

[0049] Figure 3 The transmission scenarios according to some embodiments are illustrated. Specifically, Figure 3 The repetitive transmission of the SPS-PDSCH transmission using spatial division multiplexing (SDM) 304, frequency division multiplexing (FDM) 308, or time division multiplexing (TDM) 312 is illustrated.

[0050] In the SDM 304, a first repetition may be sent using one or more first antenna ports (APs) 316 having a first TCI state, while a second repetition may be sent using one or more second APs 320 having a second TCI state. Thus, in the SDM 304, repetitions may be extended across the spatial domain.

[0051] In FDM 308, the first repetition may be sent using one or more first resource blocks (RBs) 324 having a first TCI state, while the second repetition may be sent using one or more second RBs 328 having a second TCI state. Thus, in FDM 308, the repetition may be spread across the frequency domain. FDM 308 may be FDM scheme A in which a single redundancy version (RV) is included in a time slot, or FDM scheme B in which a pair of RVs is in a time slot.

[0052] In TDM 312, a first repetition may be sent in a first receive opportunity (RO) 332 having a first TCI state, and a second repetition may be sent in a second RO 336 having a second TCI state. Thus, in TDM 312, repetitions may be spread across the time domain. TDM 312 may be a TDM scheme A in which RV pairs are included in ROs (e.g., time slots), or an inter-slot TDM scheme in which a single RV is in a RO (e.g., time slot).

[0053] In a second option for receiving SPS-PDSCH transmissions, the mode indicator may be specified by a DCI for SPS activation. This DCI (which may also be referred to as "activation DCI") may have cyclic redundancy check (CRC) bits scrambled by the configured scheduling radio network temporary identifier (CS-RNTI).

[0054] The mode indicator may comprise two bits that indicate one of the three or four operating modes discussed above for the first option.

[0055] In the case where the activation DCI is DCI format 1_0, the mode indicator field may be created by repurposing the two reserved bits (R) of the DCI, as currently defined by clause 7.3.1.2.1 of 3GPP TS 38.212 v17.4.0 (2023-01-04).

[0056] In the case where the activation DCI is DCI format 1_1, a mode indicator field may be created by adding a new mode indicator field when sending the activation DCI in the UE-specific search space (USS). Additionally / alternatively, the mode indicator field may be created by repurposing the two validation bits of the DCI, as currently defined in clause 7.3.1.2.2 of 3GPP TS 38.212 v17.4.0 (2023-01-04). For example, the validation bits may be the two most significant bits (MSBs) from the hybrid automatic repeat request (HARQ) process number or the redundancy version (RV) field.

[0057] In some embodiments, the number of joint / DL unified TCI states may be updated from two to one. For example, indicator signaling may initially provide an association of two joint / DL unified TCI states with the SPS PDSCH, and at a later time, indicator signaling may update the association in such a way that a single joint / DL unified TCI state is associated with the SPS PDSCH. The single joint / DL unified TCI state may be one of the two joint DL / TCI states or a different DL / TCI state. In this case, the UE 104 may receive subsequent repetitions of the SPS PDSCH transmission with the single joint / DL unified TCI state according to one or more of the following options. Consideration may be given to: Figure 3 Each of the mTRP regimens described.

[0058] In a first option, a single unified TCI state may be applied to receive all repetitions of the SPS PDSCH transmission, including, for example, repetitions previously associated with the second TCI state. With this option, SPS-PDSCH reception essentially falls back to the sTRP mode of operation.

[0059] Consider, for example, the case where a two-state association associates TCI state 1 with the first repetition and TCI state 2 with the second repetition, and later a single-state association is received with TCI state 3 (which may be one of TCI state 1 or TCI state 2 or a different TCI state). In this embodiment, and with reference to Figure 3, after the update, two repetitions will be received using TCI state 3 (on APs 316 and 320 if SDM 304; on RB 324 and RB 328 if FDM 308; and on RO 332 and RO 336 if TDM 312).

[0060] In the second option, upon receiving a single-state association, UE 104 may determine that the SPS PDSCH configuration configured with two joint / DL unified TCI states is implicitly deactivated or released. In this example, UE 104 may not further monitor the configured SPS PDSCH resources in anticipation of receiving an updated SPS PDSCH configuration.

[0061] In a third option, the PDSCH opportunities associated with the second TCI state may be released, disabled or deactivated. Figure 3 , UE 104 may stop monitoring AP 320 for SDM 304 , RB 328 for FDM 308 , or RO 336 for TDM 312 .

[0062] In some embodiments, two unified TCI states may be associated with a CG PUSCH. The two unified TCI states may include a unified UL TCI state or a joint unified TCI state. The CG PUSCH may be a Type 1CG or a Type 2CG. A Type 1CG may be fully configured using RRC signaling without requiring DCI. Once a Type 1CG is configured, the UE 104 may use the resources. A Type 2CG may use a combination of RRC signaling to configure resources and DCI to activate the resources for use by the UE 104.

[0063] In some embodiments, when two joint TCI states or two UL TCI states are indicated by the TCI field of the indication signaling, the UE 104 may map the two TCI states to a Type 1 CG-PUSCH transmission according to one or more of the following options.

[0064] The UE 104 may operate differently depending on the number of SRS resource sets configured in the CG configuration IE (e.g., ConfiguredGrantConfig) that configures resources for a Type 1 CG PUSCH. The SRS resource set may be configured by fields such as, for example, a pathloss reference index (pathlossReferenceIndex) indicating a reference signal index used as a PUSCH path loss reference, an SRS resource indicator (srs-ResourceIndicator) indicating an SRS resource to be used, and a precoding and number of layers (precodingAndNumberofLayers) indicating a precoding and number of layers to be used. In some embodiments, if the ConfiguredGrantConfig IE includes fields for configuring both the first SRS resource set (e.g., pathlossReferenceIndex, srs-ResourceIndicator, and precodingAndNumberofLayers) and the second SRS resource set (e.g., pathlossReferenceIndex2, srs-ResourceIndicator2, and precodingAndNumberofLayers), the UE 104 may apply both the first TCI state and the second TCI state to Type 1 CG-PUSCH transmission. Specifically, the UE 104 may use the first TCI state for PUSCH repetitions associated with the first SRS resource set, and may use the second TCI state for PUSCH repetitions associated with the second SRS resource set.

[0065] In some implementations, a set of SRS resources associated with a relatively smaller identifier may be considered a first set of SRS resources, and a set of SRS resources associated with a relatively larger identifier may be considered a second set of SRS resources.

[0066] When the ConfiguredGrantConfig IE only includes fields for configuring the first SRS resource set (for example, the ConfiguredGrantConfig IE has pathlossReferenceIndex, srs-ResourceIndicator and precodingAndNumberofLayers, but the ConfiguredGrantConfig IE does not have pathlossReferenceIndex2, srs-ResourceIndicator2 and precodingAndNumberofLayers), only the first TCI state will be associated with the SRS resource set and applied to all PUSCH repetitions.

[0067] Figure 4 4. TCI state mapping 400 is illustrated in accordance with some embodiments. For example, if the ConfiguredGrantConfig IE configures two SRS resource sets, the UE 104 can use mapping 404 in mTRP operation. Mapping 404 can map SRS resource set #1 to the first and third repetitions of the Type 1 CG PUSCH, and can map SRS resource set #2 to the second and fourth repetitions of the Type 1 CG PUSCH. Thus, odd-numbered repetitions (e.g., the first, third, etc.) can be sent using TCI state 1, and even-numbered repetitions (e.g., the second, fourth, etc.) can be sent using TCI state 2.

[0068] If the ConfiguredGrantConfig IE configures one SRS resource set, the UE 104 can use mapping 408 in the sTRP operation. Mapping 408 can map SRS resource set #1 to all repetitions of Type 1 CG PUSCH. Since SRS resource set #1 is associated with TCI state 1, all repetitions of Type 1 CG PUSCH can be sent using TCI state 1.

[0069] In some implementations, the TCI state that is considered to be the first TCI state (eg, TCI state 1) of the two indicated TCI states may be explicitly configured through RRC signaling.

[0070] For Type 2CG PUSCH, the UE 104 may rely on signaling of the mode indicator in the activation DCI. For example, when two joint TCI states or two UL TCI states are indicated by the TCI field of the indication signaling, the following process may be used to map the two TCI states for Type 2CG PUSCH transmission.

[0071] In some embodiments, the DCI activating the Type 2CG PUSCH may include a mode indicator by repurposing the two bits of the SRS resource set indicator. For example, the two bits used to activate the SRS resource set indicator in the DCI as defined in 3GPP TS 38.212 v17.4.0 (2023-01-04) may be used instead for a two-bit mode indicator. In some embodiments, the two bits may be used based on the two bits according to some embodiments. Figure 5 The operating mode table 500 is used to interpret the two-bit mode indicator.

[0072] The mode indicator field may include a value of {0,0} to indicate that the UE 104 will operate in the first sTRP mode. In the first sTRP mode, the UE 104 may use the first TCI state to send a Type 2 CG PUSCH transmission. The first TCI state may correspond to TRP 1.

[0073] The mode indicator may include a value {0, 1} to indicate that the UE 104 is to operate in the second sTRP mode. In the second sTRP mode, the UE 104 may use a second TCI state to transmit a type 2 CGPUSCH transmission. The second TCI state may correspond to TRP 2.

[0074] In some embodiments, the TCI state considered to be the "first" TCI state and the TCI state considered to be the "second" TCI state of the two indicated TCI states may be ordered based on the TCI states within the MAC-CE indicating the signaling.

[0075] The mode indicator may include a value of {1,0} to indicate that the UE 104 is to operate in the first mTRP mode. In the first mTRP mode, the UE 104 may use both the first TCI state and the second TCI state to transmit a Type 2 CG PUSCH transmission. The first TCI state (e.g., corresponding to TRP 1) may be used first (e.g., for the first repetition), and the second TCI state (e.g., corresponding to TRP 2) may be used second (e.g., for the second repetition).

[0076] The mode indicator may include a value of {1, 1} to indicate that the UE 104 is to operate in the second mTRP mode. In the second mTRP mode, the UE 104 may also use both the first TCI state and the second TCI state to transmit a Type 2 CG PUSCH transmission. However, in this mode, the second TCI state (e.g., corresponding to TRP 2) may be used first (e.g., for the first repetition), and the first TCI state (e.g., corresponding to TRP 1) may be used second (e.g., for the second repetition).

[0077] In some embodiments, when the number of joint or UL unified TCI states associated with a CG PUSCH is updated from two to one via the TCI field in indicator signaling (e.g., DCI format), one or more of the following options may be used to process a CG PUSCH that was initially configured or activated with two TCI states.

[0078] For TDM-based repetition as defined in, for example, R17, a single indicated TCI state may be applied to all PUSCH repetition opportunities. Thus, in this example, upon receiving an association update, the UE 104 may fall back to sTRP operation using a single indicated TCI state.

[0079] In some embodiments, the UE 104 may include multiple antenna panels and be configured for CG PUSCH using simultaneous uplink transmission (STxMP) across multiple panels.

[0080] Figure 6 A network environment 600 is illustrated in which a UE 104 has multiple panels and is configured for STxMP according to some embodiments. The UE 104 may be configured with a Type 2CG PUSCH activated by DCI, with three-layer PUSCH STxMP operation performed across two panels. The first transmission layer (layer #1) may be associated with the first UL panel (e.g., panel #1), while the second and third transmission layers (layers #2 and #3) may be associated with the second UL panel. Panel #1 may be associated with the first SRS resource set and the first TCI state, while panel #2 may be associated with the second SRS resource set and the second TCI state.

[0081] When switching from two TCI states to one TCI state, the UE 104 may operate based on one or more of the following options.

[0082] In a first option, the UE 104 may use a single unified TCI state to transmit all layers of the CG PUSCH transmission. Figure 6 After the UE 104 is updated to a single unified TCI state, the UE 104 may use the single unified TCI state (and its corresponding SRS resource set) for transmitting layer #1, layer #2, and layer #3.

[0083] In a second option, upon receiving a single-state association, the UE 104 may determine that Type 1 or Type 2 CG PUSCH configuration is implicitly disabled. In this example, the UE 104 may not perform further transmissions on the CG PUSCH resources in anticipation of receiving an updated CG PUSCH configuration.

[0084] In a third option, the PUSCH layer associated with the second TCI state may be implicitly deactivated. Figure 6 , UE 104 may stop transmitting layer # 2 and layer # 3. Therefore, in this embodiment, UE 104 may assume that CG PUSCH is updated from three-layer transmission to one-layer transmission, and may deactivate the layer associated with TRP 2.

[0085] In some embodiments, a fallback DCI (e.g., DCI format 0_0) may be used to activate a type 2 CG PUSCH or schedule retransmission of a CG PUSCH (type 1 or type 2). In some embodiments, a CG PUSCH configuration may include two sets of power control parameters that may be associated with SRS resource sets, respectively. For example, a CG PUSCH configuration may include a first power control parameter for a first SRS resource set (e.g., a p0-PUSCH-α (p0-PUSCH-α) value for open-loop power control and a power control loop use (powerControlLooptoUse) value for closed-loop power control) and a second power control parameter for a second SRS resource set (e.g., a p0-PUSCH-α2 value and a powerControlLooptoUse2 value). In the case where two sets of power control parameters are configured for a CG PUSCH configuration via RRC signaling, one or more of the following options may be used.

[0086] In a first option, a single TCI state may be applied to all PUSCH repetitions based on the corresponding SRS resource set. For example, the single TCI state used may be the first TCI state or the second TCI state. Whether the first TCI state or the second TCI state is used may be predetermined by, for example, a definition in 3GPP TS. Additionally or alternatively, whether the first TCI state or the second TCI state is used may be explicitly configured via RRC signaling.

[0087] In the second option, the UE may apply both indicated TCI states (if present). If only a single TCI state is indicated, the single TCI state may be applied similar to the first option.

[0088] In some examples, sDCI mTRP operation can be configured where there are two SRS resource sets with the same purpose (e.g., both are "codebook" or both are "non-codebook"). In this case, the access node 116 can add an indicator IE in one or more SRS resource set configurations. The indicator IE can provide an indication to the UE 104 whether to select the first unified TCI state or the second unified TCI state.

[0089] Figure 7An operational flow / algorithm structure 700 for receiving a PDSCH transmission based on an SPS configuration according to some embodiments is illustrated. The operational flow / algorithm structure 700 may be implemented by a UE (such as, for example, UE 104, UE 1000) or a component thereof (eg, processor 1004).

[0090] The operational flow / algorithm structure 700 may include, at 704, identifying a unified TCI state association. The unified TCI state association may be identified by receiving indication signaling that activates / indicates two TCI states for a PDSCH channel. The indication signaling may be MAC-CE-based signaling or MAC-CE+DCI-based signaling.

[0091] The operational flow / algorithm structure 700 may further include receiving an SPS configuration and an activation DCI at 708. The SPS configuration may configure resources available for the PDSCH channel. An activation DCI may then be received to activate the resources. The DCI may include DCI format 1_0 or DCI 1_1.

[0092] The operational flow / algorithm structure 700 may further include, at 712, receiving a mode indicator. The mode indicator may include one or two bits included in the SPS configuration or DCI. If the mode indicator is included in DCI format 1_0, the mode indicator may be provided by repurposing reserved bits. If the mode indicator is included in DCI format 1_1, the mode indicator may be provided by repurposing verification bits (e.g., from the HARQ process number or RV field) or through a dedicated mode indicator field.

[0093] The mode indicator may indicate that the UE will receive PDSCH transmissions using a first unified TCI state, a second unified TCI state, or both unified TCI states.

[0094] The operational flow / algorithm structure 700 may further include receiving one or two TCI states to receive the PDSCH transmission, at 716. The UE may receive the PDSCH transmission using one or more unified TCI states as indicated by the mode indicator.

[0095] In some embodiments, the unified TCI state association may be updated from associating the PDSCH with two unified TCI states to associating it with one unified TCI state. Before the update, the first of the two unified TCI states may be associated with the first PDSCH opportunity, and the second of the two unified TCI states may be associated with the second PDSCH opportunity. After the update, one TCI state may be associated with both the first and second PDSCH opportunities; or one TCI state may be associated with the first PDSCH opportunity, and the second PDSCH opportunity may be disabled or released. Alternatively, after the update, the SPS PDSCH configuration may be deactivated or released.

[0096] Figure 8 An operational flow / algorithm structure 800 for performing CG-PUSCH transmission according to some embodiments is illustrated. The operational flow / algorithm structure 800 may be implemented by a UE (such as, for example, UE 104, UE 1000) or a component therein (eg, processor 1004).

[0097] The operational flow / algorithm structure 800 may include, at 804, identifying a unified TCI state association. The unified TCI state association may be identified by receiving indication signaling that activates / indicates two TCI states for a CG-PUSCH channel. The indication signaling may be MAC-CE-based signaling or MAC-CE+DCI-based signaling.

[0098] The operational flow / algorithm structure 800 may further include receiving a CG-PUSCH configuration at 808. The CG-PUSCH configuration may be for a Type 1 CG or a Type 2 CG.

[0099] The operational flow / algorithm structure 800 may further include: at 812, determining a TCI state mapping. In some embodiments, the TCI state mapping may depend on whether the CG-PUSCH configuration includes a field for configuring one SRS resource set or two SRS resource sets. If the configuration includes a field for configuring two SRS resource sets, the TCI state mapping may map the first unified TCI state to the first PUSCH repetition and the second unified TCI state to the second PUSCH repetition. If the configuration includes a field for configuring one SRS resource set, the TCI state mapping may map the first unified TCI state to all PUSCH repetitions. In some embodiments, selecting the first unified TCI state from the two TCI states associated with the CG-PUSCH may be based on a mapping indicator in the RRC signaling.

[0100] In some embodiments, the activation DCI may include a mode indicator to indicate the uplink operating mode. The UE may determine the TCI state mapping based on the uplink operating mode. The uplink operating mode may be a first sTRP mode in which a first unified TCI state is used to send CG-PUSCH; a second sTRP mode in which a second unified TCI state is used to send CG-PUSCH; a first mTRP mode in which a first repetition of CG-PUSCH transmission is sent using the first unified TCI state and a second repetition of CG-PUSCH transmission is sent using the second unified TCI state after the first repetition is sent; or a second mTRP mode in which a first repetition of CG-PUSCH transmission is sent using the second unified TCI state and a second repetition of CG-PUSCH transmission is sent using the first unified TCI state after the first repetition is sent.

[0101] The operational flow / algorithm structure 800 may further include transmitting a CG-PUSCH transmission, at 816. The transmission of the CG-PUSCH transmission may be based on the configuration and the TCI state mapping.

[0102] Figure 9 An operational flow / algorithm structure 900 for transmitting a CG-PUSCH transmission according to some embodiments is illustrated. The operational flow / algorithm structure 900 may be implemented by a UE (such as, for example, UE 104 or 1000) or a component thereof (eg, processor 1004).

[0103] The operational flow / algorithm structure 900 may include receiving a CG-PUSCH configuration at 904. The CG-PUSCH configuration may include a first set of power control parameters associated with a first SRS resource set and a second set of power control parameters associated with a second SRS resource set. The power control parameters may include a p0-PUSCH-α value for open-loop power control and a power control loop usage value for closed-loop power control.

[0104] The operational flow / algorithm structure 900 may further include identifying two TCI states associated with the CG-PUSCH configuration at 908. The two TCI states may be identified by receiving indication signaling associating the two TCI states with the CG-PUSCH. The indication signaling may be MAC-CE-based signaling or MAC-CE+DCI-based signaling.

[0105] The operational flow / algorithm structure 900 may further include receiving a DCI format 0_0 associated with a CG-PUSCH configuration, at 912. The DCI may be a fallback DCI that activates a type 2 CG PUSCH or schedules a retransmission of a type 1 or type 2 CG PUSCH.

[0106] The operational flow / algorithm structure 900 may further include transmitting a CG-PUSCH transmission using one or more of the two unified TCI states, at 916. This may be based on DCI format 0_0 and CG-PUSCH configuration.

[0107] In some embodiments, the UE may select a first TCI state from the two TCI states based on, for example, a pre-configured setting in the 3GPP TS or based on RRC signaling. The CG-PUSCH transmission may be sent using the first TCI state.

[0108] In some embodiments, if both the first SRS resource set and the second SRS resource set are configured with codebook usage or both are configured with non-codebook usage, the UE may detect the indicator IE of the SRS resource set configuration and select the first TCI state from the two TCI states based on the indicator IE. The first TCI state may then be used for CG-PUSCH transmission.

[0109] In some implementations, the UE may use both unified TCI states to send CG-PUS CH transmissions.

[0110] Some embodiments include operational procedures / algorithm structures that supplement, from a network perspective, the operational procedures / algorithm structures 700, 800, and 900. For example, an access node (such as access node 116), network node 1100, or a component thereof (e.g., processor 1104) may implement such operational procedures / algorithm structures to configure a UE for UL / DL transmissions, transmit DL transmissions, and receive UL transmissions, as described herein.

The processor 1004 may include any type of circuit or processor circuit that executes or otherwise operates computer-executable instructions (such as program code, software modules, or functional processes from the memory / storage device 1012) to cause the UE 1000 to perform operations as described herein.

[0116] In some embodiments, the baseband processor circuit 1004A can access the communication protocol stack 1036 in the memory / storage device 1012 to communicate over a 3GPP-compatible network.

[0118] The memory / storage device 1012 may include one or more non-transitory computer-readable media including instructions (e.g., the communication protocol stack 1036) that may be executed by one or more processors in the processor 1004 to cause the UE 1000 to perform various sTRP / mTRP operations as described herein. For example, the processor 1004 may cause the UE to perform the operational flow / algorithm structure 700, 800, or 900 or any other method or process described herein.

[0119] The memory / storage 1012 includes any type of volatile or non-volatile memory that may be distributed throughout the UE 1000. In some embodiments, some of the memory / storage 1012 may be located on the processor 1004 itself (e.g., L1 cache and L2 cache), while other memory / storage 1012 is external to the processor 1004 but accessible via a memory interface.

The RF interface circuit 1008 may include various components arranged in a transmit path or a receive path. These components may include, for example, switches, mixers, amplifiers, filters, synthesizer circuits, and control circuits.

[0121] In the receive path, the RFEM receives the radiated signal from the air interface via the antenna structure 1026 and further filters and amplifies the signal (using a low-noise amplifier). The signal can be provided to the transceiver's receiver, which down-converts the RF signal to a baseband signal that is provided to the baseband processor of the processor 1004.

[0122] In the transmit path, the transmitter of the transceiver up-converts the baseband signal received from the baseband processor and provides an RF signal to the RFEM. The RFEM may amplify the RF signal through a power amplifier before radiating the signal across the air interface via the antenna structure 1026.

[0123] In various embodiments, the RF interface circuit 1008 may be configured to send / receive signals in a manner compatible with NR access technology.

[0124] The antenna structure 1026 may include antenna elements to convert electrical signals into radio waves to travel through the air and convert received radio waves into electrical signals. These antenna elements may be arranged into one or more antenna panels.

In additional examples, the driver circuitry 1022 may include: a display driver for controlling and enabling access to a display device; a touch screen driver for controlling and enabling access to a touch screen interface; a sensor driver for obtaining sensor readings from the sensor 1020 and controlling and enabling access to the sensor 1020; a driver for obtaining actuator positions of electromechanical components or controlling and enabling access to electromechanical components; a camera driver for controlling and enabling access to an embedded image capture device; and an audio driver for controlling and enabling access to one or more audio devices.

[0128] The PMIC 1024 may manage power provided to various components of the UE 1000. Specifically, with respect to the processor 1004, the PMIC 1024 may control power source selection, voltage scaling, battery charging, or DC-DC conversion.
