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: In some access networks, group-based beam reporting configured for a UE may be based on heuristics and/or based on UE implementation, and therefore, may lack adequate information regarding joint channel properties for simultaneous transmission and reception on a channel configured with a base station. Configurations of UEs and base stations are described herein that support various feedback metrics for resource grouping in association with transmission and reception operation modes and/or channel states, such as MIMO schemes, SINRs, channel properties, and the like. Base stations may dynamically indicate metrics to be reported by UEs so that simultaneous transmission and reception may be sufficiently supported.

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.

Abstract: Certain aspects of the present disclosure provide techniques for control channel resource grouping and spatial relation configuration. Aspects of the present disclosure provide a method of wireless communication by a user equipment (UE). The method generally includes receiving an indication of one or more groupings of one or more control channel resources within a configured bandwidth. Each grouping is associated with a spatial relation. The UE applies a spatial relation for a control channel transmission using one or more control channel resources in a grouping of the one or more groupings. The grouping is associated with the spatial relation.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify one or more candidate beams available for communication between the UE and a BS to replace another beam that is configured for communicating between the UE and the BS. The UE may transmit, based at least in part on identifying the one or more candidate beams, a communication that includes a new beam information (NBI) field and/or contents of the NBI field. Numerous other aspects are provided.
