Abstract: Apparatus, methods, and computer-readable media for facilitating timing advancing for bidirectional full-duplex sidelink communication are disclosed herein. An example method for wireless communication at a first UE includes performing a self-interference measurement on a unicast link with a second UE to determine a link quality. The example method also includes applying a TA adjustment for transmission or reception with the second UE based on the self-interference measurement.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may relay sidelink data between a first remote UE and a second remote UE. The UE may facilitate end-to-end physical layer security for the sidelink data relayed between the first remote UE and the second remote UE based at least in part on a first link key associated with a first link between the first remote UE and the UE and a second link key associated with a second link between the UE and the second remote UE. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described. A communication device, such as a user equipment (UE) may determine a transmit diversity configuration indicating a transmit diversity criterion for declaring a result of a channel access procedure for a plurality of component carriers in a shared radio frequency spectrum band. The UE may perform the channel access procedure for the plurality of component carriers in the shared radio frequency spectrum band to determine the result of the channel access procedure based at least in part on the transmit diversity criterion. As a result, the UE may transmit or refrain from transmitting a message over at least one component carrier of the plurality of component carriers based at least in part on the result of the channel access procedure.

Abstract: The apparatus may be a first UE. The first UE may determine a first set of candidate BPLs associated with a first SL and a second set of candidate BPLs associated with a second SL. The first UE may further determine a configuration for FD beam training based on the determined first set of candidate BPLs and the determined second set of candidate BPLs, the FD beam training configuration may include multiple instances for which the first UE transmits and receives RS at a same time. The apparatus may also select, based on the determined FD beam training configuration, a first BPL in the first set of candidate BPLs for the first SL and a second BPL in the second set of candidate BPLs for the second SL. The first UE may establish FD communication with the second UE based on the selected first BPL and the selected second BPL.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a plurality of sidelink transmissions associated with a spatial division multiplexing (SDM) configuration. The UE may fail to decode at least one sidelink transmission of the plurality of sidelink transmissions. The UE may transmit feedback indicating the failure to decode the at least one sidelink transmission, wherein the feedback includes an indication of at least one layer of the SDM configuration associated with the at least one sidelink transmission. Numerous other aspects are described.

Abstract: Method and apparatus for a prioritization of synchronization signals for NR-LTE in-band coexistence. The apparatus detects a first sidelink synchronization signal from a first RAT and a second sidelink synchronization signal from a second RAT. The apparatus determines a priority between a synchronization source associated with the first RAT and the second RAT. The apparatus transmits data using a timing based on a determination of the priority between the first RAT and the second RAT. The apparatus determines to transmit a sidelink synchronization signal to be the synchronization source in response to detecting the first sidelink synchronization signal from the first RAT. The apparatus determines to transmit at least one of the first sidelink synchronization signal or the second sidelink synchronization signal.

Abstract: Aspects relate to techniques for sidelink transmissions scheduled by network entities. A UE may receive a resource reservation message from a transmitting UE indicating resources granted by a network entity for a first sidelink transmission. The UE may detect a conflict between the first sidelink transmission and a second sidelink transmission and transmit a conflict indication in response to detecting the conflict. The UE may transmit the conflict indication to the transmitting UE or to the network entity. In some examples, the transmitting UE receiving the conflict indication may report the conflict to the network entity.

Abstract: Certain aspects of the present disclosure provide techniques for channel estimation for two-stage sidelink control using sidelink data channel demodulation reference signals (DMRS). A user equipment (UE) can transmit DMRS for the sidelink data channel. The UE may transmit the second stage of the sidelink control using antenna ports or a precoder used for the sidelink data channel. The receiving device may receive the DMRS, estimate the channel, and demodulate the second stage of the sidelink control based on the estimated channel. The receiving device may flexibly determine the DMRS to use for the estimation and demodulation.
