    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.

    Abstract: Disclosed are techniques for wireless positioning. In an aspect, a road-side unit (RSU) may join a first sidelink (SL) ranging session between a first user equipment (UE) and a second UE. The RSU may perform SL ranging with the first UE to determine first ranging information comprising at least a RTT to the first UE. The RSU may perform SL ranging with the second UE to determine second ranging information comprising at least a RTT to the second UE. The RSU may send the first ranging information and the second ranging information to at least one of the first UE or the second UE, or calculate a range between the first UE and the second UE based on the first ranging information and the second ranging information, and send the range to at least one of the first UE and the second UE.

    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, an inter-UE coordination message comprising an indication of a first sidelink resource, of a set of sidelink resources, corresponding to a transmission by the second UE. The UE may transmit a sidelink communication using a second sidelink resource, of a subset of candidate sidelink resources of a set of candidate resources, based at least in part on the indication of the first sidelink resource and a communication relationship between the first UE and the second UE. Numerous other aspects are described.

    Abstract: Methods, systems, and devices for wireless communications are described. The method may include a first wireless device transmitting, to a third wireless device associated with a signal relaying device, a first message querying whether the third wireless device is able to establish a first communications link with a second wireless device. The first wireless device may receive, from the third wireless device, signaling indicative of whether the third wireless device is able to establish the first communications link with the second wireless device and communicate with the second wireless device via a second communications link using a signal relaying device of the one or more signal relaying devices associated with the third wireless device based on the signaling.

    Abstract: A first UE may determine to communicate with a second UE, but may maintain or establish a RRC connection with a third UE upon determining that potential interference may occur between the first UE and the third UE. The potential inference may be a received interference in which the first UE receives interference from the third UE as a result of a communication between the third UE and a fourth UE, or a transmitted interference in which the first UE causes interference to the third UE as a result of a communication between the first UE and the second UE. The first UE may communicate mitigation information to the third UE through the RRC connection, where the interference mitigation information may be associated with the communication between the first UE and the second UE or the communication between the third UE and the fourth UE.
