Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer-readable media, for implementing signaling for indicating a scheduled full duplex (FD) uplink (UL) and downlink (DL) traffic scheduling combination for differentiation of FD traffic. In some aspects, a BS may transmit a downlink control information (DCI) message that includes an indication of the scheduled FD UL and DL traffic scheduling combination. The FD UL and DL traffic scheduling combination may identify scheduled UL and DL transmissions for FD mode operation. The UE may receive the DCI message and identify the scheduled FD UL and DL traffic scheduling combination. In some aspects, the BS may provide a DCI message to the UE that indicates whether a DL transmission is being scheduled that at least partially overlaps with a scheduled UL transmission. The UE may initiate a power save mode based on the received DCI message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a second UE, a first message that indicates a sidelink bandwidth part (BWP) switch, for the second UE, to a first sidelink BWP, where the first message includes an indication of the first sidelink BWP and a first sidelink resource pool in the first sidelink BWP. The first UE may transmit, to the second UE, a second message that confirms the sidelink BWP switch for the second UE. The first UE may receive, from the second UE, a third message that activates the sidelink BWP switch, for the second UE, to the first sidelink BWP. Numerous other aspects are described.

Abstract: Apparatus, methods, and computer-readable media for facilitating SSB-subset selection based RACH with base station-side beam prediction are disclosed herein. An example method for wireless communication at a user equipment (UE) includes measuring one or more synchronization signal block (SSB) subsets of an SSB burst set including multiple SSBs grouped into SSB subsets. The example method also includes transmitting, to a base station, a random access message indicating information for at least one SSB subset from the one or more SSB subsets and measurement information for one or more SSBs of the at least one SSB subset.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a second UE, a reference signal used for initial beam-pairing (IBP) (IBP-RS) based at least in part on a destination identifier (ID), wherein one or more of an IBP-RS sequence, an IBP-RS configuration, or an IBP-RS resource is based at least in part on the destination ID. The first UE may receive, from the second UE and based at least in part on the IBP-RS, a beam-pairing response signal for a beam association. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. For example, a source distributed unit (DU) may receive, from a user equipment (UE), a measurement report indicating at least one transmission configuration indicator state (TCI) state associated with a target DU. The source DU may transmit, to the target DU, an indication of a set of candidate TCI states from the at least one TCI state for a dynamic cell switch of the UE from a source cell of the source DU to a target cell of the target DU. As such, the UE may transmit, to the target DU, a random access message or an uplink message in accordance with a first TCI state from the set of candidate TCI states.

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: Methods, systems, and devices for wireless communication are described. Sidelink user equipment (UE) may perform a sidelink beam management procedure in accordance with a sidelink beam management configuration. A first UE may receive sidelink reference signals via a first set of time-frequency resources. As part of the sidelink beam management procedure, the first UE may transmit a sidelink message including feedback and beam management information (e.g., measurements) corresponding to the sidelink reference signals, which a second UE may use for the sidelink beam management procedure. In addition, the first UE may receive a set of demodulation reference signals (DMRSs) associated with a sidelink channel via a second set of time-frequency resources which may be non-overlapping, or at least partially overlapping, with the first set of time-frequency resources. The first UE may use the sidelink reference signals, the DMRSs, or both for sidelink beam management.
