Abstract: In some implementations, a target user equipment (UE) may receive, from an initiator UE via an SL interface, a discovery request corresponding to an SL positioning session, wherein the target UE comprises a plurality of transmission/reception points (TRPs). The target UE may determine, from the discovery request, the initiator UE is incapable of associating each TRP of the plurality of TRPs with the target UE. Responsive to determining the initiator UE is incapable of associating each TRP of the plurality of TRPs with the target UE, the target UE may participate in the SL positioning session with the target UE by either: (i) using only one TRP of the plurality of TRPs during the SL positioning session, or (ii) using each TRP of the plurality of TRPs such that each TRP operates as a distinct UE.

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 visual feature sharing between wireless communication devices for relative pose determination. A first wireless communication device may transmit a request for visual feature sharing to a second wireless communication device and in response receive a message from the second wireless communication device including a plurality of features (e.g., keypoints) of an image captured by the second wireless communication device. The first wireless communication device may then calculate a relative pose of the first wireless communication device with respect to the second wireless communication device based on an association between the features provided by the second wireless communication device and additional features obtained from an additional image captured by the first wireless communication device.

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: 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: A vehicle-enabled user equipment (VUE) and related techniques are disclosed. In one aspect, the VUE issues a periodic broadcast, or signals a response to a requesting source, identifying its location management capability (LMC). The UE forms a link with a recipient VUE of the broadcast to perform joint localization of the pedestrian UE (PUE). Joint localization by VUE and another VUE may be performed by VUEs and PUEs in the region exchanging ranging signals and ego measurements. The VUE determines a location jointly of the PUE. The location can be determined upon a request, periodically, or in response to a triggered event.

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.
