Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine configuration information associated with a periodic beam failure detection reference signal (BFD-RS) for a wireless channel that has a listen-before-talk requirement. The UE may monitor the wireless channel for the periodic BFD-RS or an aperiodic BFD-RS linked to the periodic BFD-RS based at least in part on one or more parameters in the configuration information that relate to mitigating non-transmission of the periodic BFD-RS in a scheduled occasion. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a transmission configuration indicator (TCI) identifying a TCI state. The UE may associate the TCI state with one or more channels or reference signals based at least in part on a configured association. The UE may communicate using the one or more channels or reference signals based at least in part on associating the TCI state with the one or more channels or reference signals. Numerous other aspects are described.

Abstract: A wireless communication device is described. The wireless communication device includes a receiver configured to receive a message indicating a transmission configuration indicator (TCI) state. The wireless communication device also includes a processor configured to determine the TCI state based on the message, a non-serving cell identifier, and a received reference signal from a non-serving cell.

Abstract: Aspects presented herein may enable a UE and/or a base station to identify a TCI state for each of the multiple TRPs when the DCI does not include a TCI state. For examples, aspects presented herein may enable the UE and/or the base station to identify TCI states from different TRPs based at least in part on one of a default beam rule, the TCI state used for transmitting PDCCH, or the TCI state used for transmitting previous/last PDSCH. In one aspect, an apparatus receives a single DCI from one TRP of a base station or multiple DCIs from multiple TRPs of the base station that do not contain a TCI state. Then the apparatus receive PDSCH from the multiple TRPs of the base station based on a TCI state in which the PDSCH is to be transmitted from each of the multiple TRPs of the base station.

Abstract: An apparatus, e.g., a UE, for resolution of conflicts between HD and FD configurations is disclosed. The UE receives a configuration indicating that a first set of symbols is configured for HD communication with at least one of D symbols, U symbols, or F symbols in which the F symbols are configured as D or U. The UE receives DCI scheduling FD communication including an FD transmission and an FD reception on a second set of symbols. The second set of symbols have a third set of symbols in common with the first set of symbols. The third set of symbols have conflicting HD and FD configurations. The UE cancels, based on the conflicting HD and FD configurations of the third set of symbols, at least one of the FD transmission or the FD reception in the third set of symbols.

Abstract: In operation, the UE in the cell (SpCell/SCell) may be configured to operate with beam group specific BFRs, cell-level BFRs, or combinations of them under a beam failure configuration that is determined according to various rules. A method of wireless communication performed by a user equipment (UE) and a UE is disclosed. The method includes determining a beam failure configuration for a serving cell, the beam failure configuration including at least one of a beam failure parameter of a beam group or a beam failure parameter of a cell; and detecting, in the serving cell based at least in part on the beam failure configuration, a beam failure recovery (BFR) based at least in part on the beam failure configuration. The beam failure configuration is determined based on various rules that control the operation of the BFR.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a timing advance (TA) offset value for a high frequency range operating band. The UE may communicate in the high frequency range operating band, in accordance with the TA offset value. In some aspects, a UE may receive an indication of at least one of a TA offset value associated with a full-duplex communication mode of a base station or a TA offset value associated with a half-duplex communication mode of a base station. The UE may communicate, with the base station, in accordance with at least one of the TA offset value associated with the full-duplex communication mode of the base station or the TA offset value associated with the half-duplex communication mode of the base station.
