Abstract: The apparatus may be a first device at a first UE. The first device may be the first UE itself. The first UE may be configured to receive, from a second UE, a first reservation of an SL resource for a first SL transmission. The first UE may further be configured to receive, from a third UE, a second reservation of the SL resource for a second SL transmission within a threshold amount of time following the receipt of the first reservation. The first UE may also be configured to transmit a collision indication based on a collision parameter, the collision parameter being based on reception of the first reservation and the second reservation within the threshold amount of time.

Abstract: In an aspect, the disclosure provides a method of wireless communication for a first user equipment (UE). The method may include decoding, at a first user equipment (UE), sidelink control information (SCI) transmitted by a plurality of second UEs reserving a set of resources for sidelink transmission to the first UE. The method may also include detecting, at the first UE, a potential resource collision between the plurality of second UEs at the set of resources based on decoding of the SCI. The method may further include generating a pre-collision message that identifies the set of resources that are susceptible to the resource collision. The method may further include transmitting the pre-collision message from the first UE to the plurality of second UEs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a mobile station may select a vehicle-to-anything (V2X) resource from a resource pool partitioned between New Radio (NR) V2X resources and Long Term Evolution (LTE) V2X resources if an NR V2X traffic parameter does not satisfy a traffic threshold, or from a non-partitioned resource pool if the NR V2X traffic parameter satisfies the traffic threshold. The mobile station may transmit a V2X communication in the V2X resource. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication at a first user equipment (UE) are described. A first UE may transmit control signaling to reserve a first set of time and frequency resources for a sidelink transmission. In some examples, the control signaling may indicate one or more parameters to be used by a second UE to identify a second set of time and frequency resources for performing a full-duplex communication with the first UE. In some examples, the first UE may then communicate with the second UE based on the reserved first set of time and frequency resources and the indicated one or more parameters associated with the second set of time and frequency resources.

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: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may transmit a trigger message to a second UE, where the trigger message triggers a channel state information (CSI) report that includes a first CSI reporting mode of a set of CSI reporting modes and a reporting quantity for the first CSI reporting mode. For a first reporting quantity, the first UE may trigger the second UE to transmit a CSI reference signal (RS), and the first UE may then receive the CSI-RS to determine CSI based on the CSI-RS. Additionally or alternatively, for other reporting quantities, the first UE may transmit the CSI-RS to the second UE, and the second UE may transmit channel state feedback to the first UE based on measuring CSI for the received CSI-RS, where the first UE determines the CSI based on the channel state feedback.

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: 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.
