Abstract: Aspects are provided which allow a UE to achieve sidelink parameter coordination through various signaling in clustered FL or peer-to-peer FL. The UE provides a first ML model information update and a measurement associated with the update. The UE obtains an aggregated ML model information update aggregating the first update with a second ML model information update of either a first network node in a FL cluster including the UE or a second network node in a second FL cluster. The UE provides a sidelink communication parameter in SCI to a network node, which parameter is an output of an ML model associated with the aggregated ML model information update. As a result, UEs may derive common SCI parameters from their updated ML models to apply in sidelink communications, thereby leading to maximized packet reception rate, maximized throughput, or minimized latency in communication.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a transmitter user equipment (UE) transmits, by a transmitter transmit-receive point (TRxP) of the transmitter UE on a transmit beam, a self-interference management reference signal (SIM-RS) during a first beam training occasion shared among a plurality of UEs for transmitting beam training reference signals (BT-RS) for sidelink communications among the plurality of UEs, and measures, by a receiver TRxP of the transmitter UE on a receive beam, self-interference at the receiver TRxP caused by transmission of the SIM-RS by the transmitter TRxP.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a method of wireless communication performed by a first pedestrian user equipment (PUE) includes performing a ranging operation to a set of UEs, the set including at least a second PUE, and providing ranging data to a third entity, the third entity comprising a vehicle user equipment (VUE) or a road-side unit (RSU). The set of UEs may be randomly selected or selected using a selection algorithm. The set of UEs may be selected by the PUE or by the third entity. The ranging data may include the location of the first PUE, and may include a report on the battery status of the first PUE. The third entity may use the ranging data to update estimated positions of the first PUE and the set of UEs.

Abstract: Apparatus, methods, and computer-readable media for facilitating scrambling of sidelink control information for sidelink communication are disclosed herein. The scrambling of the SCI may include scrambling CRC, scrambling information bits, and/or scrambling channel bits. An example method for wireless communication at a user equipment UE includes scrambling at least a portion of SCI. The example method also includes transmitting the SCI carrying control information for a sidelink transmission. In another aspect, an example method for wireless communication at a UE includes receiving SCI having scrambled bits. The example method also includes decoding the SCI based on information known to the 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 base station or a roadside unit (RSU), information associated with one or more security keys for sidelink communications, wherein the information includes at least one of a base key, the one or more security keys, or one or more parameters for deriving the one or more security keys. The UE may transmit, to a second UE, a sidelink communication that is scrambled using a security key of the one or more security keys. Numerous other aspects are described.

Abstract: Aspects presented herein may enable a wireless device to perform an SL ranging based on a single-sided PRS transmission. In one aspect, a first wireless device transmits one or more reference signals to at least one RIS associated with a second wireless device. The first wireless device receives one or more reflected reference signals reflected from the at least one RIS. The first wireless device calculates a signal RTT based on the one or more reference signals and the one or more reflected reference signals. In another aspect, a second wireless device transmits, to a first wireless device, information indicating a time, a duration, or a periodicity in which at least one RIS associated with the second wireless device is to be activated. The second wireless device activate the at least one RIS based on the information.
