Abstract: A user equipment (UE) transmits, to a base station, UE capability information that corresponds to a maximum number of configured pathloss reference signals and/or a maximum number of activated pathloss reference signals. Then, the base station configures the UE for a number of configured pathloss reference signals that is less than or equal to the maximum number of configured pathloss references signals and/or activates a number of pathloss reference signals based on the UE capability information that is less than or equal to the maximum number of activated pathloss references signals.

Abstract: Aspects relate to mechanisms for wireless communication devices to utilize transmission configuration indication (TCI) field invalidation after PDSCH beam setting. A user equipment (UE) detecting a beam failure on a connected beam. The UE transmits a beam failure recovery request. The beam failure recovery request includes an indication of a candidate beam. The UE receives a first message including a beam failure recovery response and a second message including downlink control information (DCI) for scheduling a physical downlink shared channel (PDSCH). The UE applies the candidate beam to the PDSCH when the second message is received at least a predetermined number of symbols after receiving the first message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a channel state information (CSI) reporting configuration for a CSI report, wherein the CSI reporting configuration indicates that the CSI report is to include a layer 1 signal to interference plus noise ratio (L1-SINR). The UE may determine a number of CSI processing units (CPUs) occupied for processing of the CSI report that is to include the L1-SINR. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate a layer one reference signal received power (L1-RSRP) measurement report to include an indication of L1-RSRP measurements associated with one or more synchronization signal bocks (SSBs) included in an SSB set, wherein the SSB set is identified, from a plurality of SSB sets, in the L1-RSRP measurement report by an SSB set indicator, and wherein the one or more SSBs are identified in the L1-RSRP measurement report by respective SSB indexes that index into the SSB set. The UE may transmit the L1-RSRP measurement report. Numerous other aspects are provided.

Abstract: Aspects are provided which allow a base station to dynamically select or indicate an active CORESET associated with a search space or set of PDCCH candidates. The base station selects, for at least one UE, an active CORESET associated with a search space for a period of time. The base station transmits a dynamic indication of the active CORESET associated with the search space to the at least one UE. A UE receives the dynamic indication of the active CORESET associated with the search space for the period of time. The UE then monitors for a downlink control channel during the period of time based on the dynamic indication of the active CORESET.

Abstract: A UE determines a default beam for a physical downlink shared channel (PDSCH) that is independent of a beam for a physical downlink control channel (PDCCH). The default PDSCH beam may be determined based on information received in a medium access control-control element (MAC-CE), or a radio resource control (RRC) message, a downlink control information (DCI). The default PDSCH beam may be determined based on at least one active transmission configuration indication (TCI) state for the PDSCH.

Abstract: Methods, systems, and devices for wireless communications are described. A base station and a user equipment (UE) with a defined capability may communicate using beamformed wireless communications. The defined capability may be that the UE may support fewer activated physical downlink shared channel (PDSCH) transmission configuration indicator (TCI) states than activated control resource set (CORESET) TCI states. The defined capability UE and the base station may implement techniques to determine which TCI state to use when the UE supports fewer activated PDSCH TCI states than activated CORESET TCI states. The UE may use an activated PDSCH TCI state selected by a media access control (MAC) control element (CE), an activated TCI state of a specific CORESET, a TCI indicated in scheduling downlink control information, or an activated PDSCH TCI state selected by a radio resource control (RRC) message.
