Abstract: A base station may identify a configuration of one or more time gap periods associated with FD beam pair quality measurement. The base station may transmit, to the UE, and the UE may receive, from the base station, an indication of the configuration of the one or more time gap periods associated with FD beam pair quality measurement. The UE may perform, during the one or more time gap periods, one or more measurements of a quality of one or more FD beam pairs. Each of the one or more FD beam pairs may include an uplink beam and a downlink beam. The UE may identify at least one failed FD beam pair in the one or more FD beam pairs based on the one or more measurements of the quality of the one or more FD beam pairs and an SI measurement.

Abstract: The base station may transmit a mode switch indication to a UE to switch from a first duplex mode to a second duplex mode. The UE may activate or deactivate one or more antenna panels and the UE and the base station may communicate with each other based on the mode switch indication. The second duplex mode may be FD mode, and the mode switch indication may be transmitted a threshold number of symbols or slots prior to the FD symbols. The slot format pattern may not include FD symbol, and the base station and the UE may communicate bidirectional signals in FD mode using the flexible symbols. The second duplex mode may be HD mode. The slot format pattern may include the FD symbols, and the base station and the UE may transmit or receive signals in HD mode using the FD symbols as the flexible symbols.

Abstract: Certain aspects of the present disclosure provide techniques for indicating an overlap of downlink transmissions with one or more random access channel occasions (ROs). A method that may be performed by a user equipment (UE) includes receiving signaling from a base station (BS) including an indication of whether one or more ROs will overlap with downlink transmissions in one or more periods of time, transmitting, to the BS based on the indication, a random access channel (RACH) preamble in an RO of the one or more ROs during the one or more periods of time, and performing a RACH procedure with the BS based on the transmitted RACH preamble.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, in a full duplex transmission mode, at least one downlink control information (DCI) transmission for scheduling an uplink communication and a downlink communication, wherein the at least one DCI transmission indicates a full duplex beam pair including a first beam associated with the uplink communication and a second beam associated with the downlink communication. The UE may communicate with at least one wireless communication device based at least in part on the uplink communication and the downlink communication. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit, and a user equipment (UE) may receive, downlink control information (DCI) that indicates a transmission configuration indication (TCI) state associated with a common bema for joint downlink and uplink communication, downlink communication only, or uplink communication only. The UE and the base station may communicate on one or more of a downlink or an uplink using the common beam associated with the TCI state indicated in the DCI. 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 receive downlink control information (DCI) that schedules an aperiodic channel state information reference signal (CSI-RS) report. The UE may determine, based at least in part on the DCI, a time duration between an end of the DCI and a start of a communication on a physical uplink shared channel that includes the aperiodic CSI-RS report. The time duration may be based at least in part on an aperiodic CSI beam switch latency threshold. The UE may generate the aperiodic CSI-RS report based at least in part on a CSI-RS measurement. The UE may transmit the aperiodic CSI-RS report based at least in part on the DCI associated with the time duration. Numerous other aspects are provided.
