Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may select, based at least in part on channel sensing, one or more subchannels for transmitting information for coordinating sidelink resources with one or more other UEs. The first UE may transmit, to at least a second UE, sidelink control information (SCI) that indicates the one or more subchannels and one or more data transmission occasions in which the information is to be transmitted. Numerous other aspects are described.

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: 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: 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.
