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: Aspects relate to techniques for enabling co-channel coexistence in different radio access technologies (RATs) for sidelink communication. A wireless communication device may be configured to receive at least one resource reservation message using a first RAT. For example, each resource reservation message may identify at least one resource of a plurality of resources of a sidelink channel for a respective sidelink transmission using the first RAT. The wireless communication device may further be configured to estimate a channel occupancy of the sidelink channel of a second RAT based on measurements obtained over a total number of the plurality of resources and the at least one resource reservation message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiving (Rx) user equipment (UE) may receive, from a transmitting (Tx) UE, sidelink control information (SCI). The Rx UE may determine an Rx-side block error rate (BLER) based at least in part on the SCI. The Rx UE may perform a beam failure recovery based at least in part on the Rx-side BLER satisfying a threshold. 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 presented herein improve congestion control mechanism for UEs with multiple TRPs, where at least one of the SL RSSI measurement, the CBR measurement, the CR evaluation and/or the congestion control mechanism for the UE is optimized. In one aspect, the apparatus evaluates a CR for each TRP of a plurality of TRPs at the UE. The apparatus determines whether the UE is allowed to transmit on one or more of the TRPs of the plurality of TRPs based at least on the evaluated CR for each TRP of the plurality of TRPs and on at least one CR limit. The apparatus transmits on at least one TRP of the one or more of the TRPs based on the determination whether to transmit on the one or more TRPs.
