Abstract: The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a UE and/or a base station. The apparatus can receive SSB grouping information associated with one or more SSB groups, each of the one or more SSB groups including one or more TRPs. The apparatus can also receive at least one of TCI information or QCL information, each of the TCI information and the QCL information indicating an SSB of the one or more SSB groups that is associated with a downlink Tx beam for downlink data or an uplink Rx beam for uplink data. Additionally, the apparatus can communicate the downlink data from or the uplink data to TRPs in a same SSB group or TRPs in different SSB groups based on at least one of the SSB grouping information, the TCI information, or the QCL information.

Abstract: A configuration for configuring and updating the spatial relationship of multiple physical uplink control channel (PUCCH) resources in a single message, thereby reducing signaling overhead. A user equipment (UE) constructs a message associated with at least one of a plurality of component carriers (CCs) or a plurality of bandwidth parts (BWPs) indicating a same spatial relation for the at least one of the plurality of CCs or the plurality of BWPs. The UE transmits the message to a base station. The base station transmits a message to the UE configuring multiple spatial parameters for the at least one of the plurality of CCs, the plurality of BWPs, or a plurality of uplink/downlink resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first node may transmit, to a second node on a beamformed link from the first node to the second node, a first signal, wherein the first node and the second node are associated with common timing; determine whether a second signal, based at least in part on the first signal, is received on a beamformed link from the second node to the first node; and transmit a third signal based at least in part on receiving the second signal or perform a sidelink beam failure recovery procedure based at least in part on determining that the second signal is not received. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for applying uplink transmission configuration indicator (TCI) states with downlink reference signals to codebook based physical uplink shared channel (PUSCH) transmissions. An example method generally includes receiving, from a network entity, signaling of an uplink transmission configuration indicator (TCI) state with a target codebook based uplink transmission signal, determining if the TCI state has a source downlink reference signal (RS) and deciding how to process the codebook based uplink transmission based on the determination.

Abstract: Certain aspects of the present disclosure provide techniques that may allow a base station and user equipment (UE) to use uplink transmission configuration indication (TCI) states. An example method generally includes providing, to a network entity, signaling indicating the UE supports uplink Transmission Configuration Indicator (TCI) states indicating one or more quasi co-location (QCL) types for one or more reference signals (RS) to be applied to an uplink transmission, receiving UL TCI after sending the indication, and sending the uplink transmission in accordance with the uplink TCI.

Abstract: Certain aspects of the present disclosure are directed to a method for wireless communication. The method generally includes receiving a configuration of trigger states for channel state information (CSI)-reference signal (RS) reporting, receiving a first downlink control information (DCI) activating one of the trigger states, receiving CSI-RS in accordance with the activated one of the trigger states, and processing the CSI-RS.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for indicating an update to be applied to uplink and downlink beams. A method that may be performed by a user equipment (UE) generally includes receiving, from a network entity, signaling indicating an update to a pair of transmit and receive beams used by the UE for uplink and downlink transmissions, respectively, and processing at least one of uplink or downlink transmissions in accordance with the update. A method that may be performed by a base station (BS) generally includes sending, to a UE, signaling indicating an update to a pair of transmit and receive beams used by the UE for uplink and downlink transmissions, respectively, and processing at least one of uplink or downlink transmissions in accordance with the update.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select a first resource, of a plurality of resources, for transmission of a request to initiate a beam failure recovery procedure. The UE may determine that another transmission is scheduled contemporaneously with the transmission of the request to initiate the beam failure recovery procedure using the first resource and is to be transmitted using the first resource. The UE may select a second resource for transmission of the request to initiate the beam failure recovery procedure based at least in part on the determination that the other transmission is scheduled contemporaneously with the transmission of the request to initiate the beam failure recovery procedure and is to be transmitted using the first resource. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide techniques for beam failure detection and related timing determinations, such as for applying a default beam after beam failure recovery response (BFRR) message. A method by a user equipment (UE) may include detecting failure of a beam associated with a first cell. The detecting can include performing beam failure detection (BFD) of a beam pair link (BPL) associated with the first cell (e.g., secondary cell (Scell)). The first cell can be in carrier aggregation (CA) with a second cell. The UE may send a beam failure recovery request (BFRQ) message on a second cell (e.g., a primary cell (Pcell)). The BFRQ message can include a candidate recovery beam for the first cell. The UE can receive a BFRR message on the second cell and determine a duration from reception of the BFRR message until using a default beam for communications on the first cell.

Abstract: A user equipment (UE) transmits capability information to a base station indicating a first number of active transmission configuration indication (TCI) states or active spatial relations supported by the UE per group of bandwidth parts (BWPs) or per group of component carriers (CCs) for use in receiving control information or data. The UE receives, from the base station, a configuration of a second number of active TCI states or active spatial relations for the group of BWPs or the group of CCs that is limited to be less than or equal to the first number of active TCI states or active spatial relations supported by the UE. The UE monitors for downlink communication based on the second number of active TCI states. The UE uses the active spatial relations for uplink transmissions.
