Abstract: Wireless communications systems and methods related to communicating control information are provided. A method of wireless communication performed by a first sidelink user equipment (UE) may include transmitting, to a second sidelink UE, a first sidelink synchronization block (S-SSB) in a scheduled S-SSB slot, performing a first listen-before-talk (LBT) procedure in an unlicensed frequency band, and transmitting, to the second sidelink UE, a second S-SSB in a slot before a next scheduled S-SSB slot based on the first LBT procedure being unsuccessful.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a first report indicating a measurement for a first beam based at least in part on a source reference signal to a network entity. The network entity may transmit control signaling configuring the UE to report a differential measurement for the source reference signal. The UE may determine the differential measurement for the source reference signal by measuring a demodulation reference signal that is quasi co-located with the reference signal. The UE may transmit a second report indicating the differential measurement for the source reference signal to the network entity.

Abstract: Certain aspects of the present disclosure provide techniques for enhanced scheduling request (SR) transmission for skipped channel state information (CSI) reports. An example method, performed at a user equipment (UE), generally includes receiving first signaling configuring the UE with physical uplink control channel (PUCCH) resources for periodically transmitting channel state information (CSI), wherein the first signaling indicates at least one condition for CSI report skipping, and transmitting enhanced scheduling information on the PUCCH resources if the at least one condition is met.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information indicating an uplink gap. The UE may transmit a reference signal in the uplink gap. The UE may perform at least one of a self-interference measurement or a beam pair calibration for full-duplex communication based at least in part on the reference signal. Numerous other aspects are described.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to mobility techniques that allow for mobility of a user equipment (UE) between a set of cells. A method that may be performed by a UE includes receiving signaling configuring the UE with a set of cells that support physical (PHY) layer or medium access control (MAC) layer mobility signaling and with a measurement configuration for the set of cells, reporting, to a network entity, measurements for at least some of the set of cells in accordance with the measurement configuration, and receiving, from the network entity, PHY layer or MAC layer mobility signaling to move the UE to one of the cells in the set, wherein the mobility signaling is based, at least in part, on the reported measurements.

Abstract: Certain aspects of the present disclosure provide techniques for beam selection for random access. A method that may be performed by a user equipment (UE) includes receiving, from a network entity, via a first beam, system information associated with at least a first plurality of beams that are within a coverage area of the first beam. The method also includes selecting a second beam among at least the first plurality of beams based at least in part on the system information and performing a random access procedure via the selected second beam.

Abstract: A user equipment (UE) receives one or more timing advance commands from a non-terrestrial network (NTN). The UE resets, after a GNSS fix, a cumulative timing advance value based on the one or more timing advance commands from the NTN and transmits an uplink transmission with a timing advance based on a self-estimated delay and the cumulative timing advance value. The UE may adjust a self-estimated delay based on at least one GNSS fix. The UE may transmit an uplink transmission with a timing advance based on the adjusted self-estimated delay and a cumulative timing advance value based on the one or more timing advance commands from the NTN.
