Abstract: A method includes causing, at a first user equipment (UE), transmission of at least one positioning reference signal (PRS) to a second UE via a sidelink (SL) communication based on first positioning assistance data. The transmission enables the second UE to determine positioning measurements from at least part of the at least one PRS.

Abstract: Aspects are described for a user equipment (UE) comprising a transceiver configured to enable wireless communication with a serving cell and a target cell and a processor communicatively coupled to the transceiver. The processor is configured to receive a handover command from the serving cell. The handover command comprises an epoch index and ephemeris information of the target cell. The processor is further configured to determine an epoch time of the target cell based on the epoch index and perform time synchronization with the target cell using the epoch time and the ephemeris information.

Abstract: The exemplary embodiments relate to a user equipment (UE) performing radio link monitoring of a sidelink. The UE may transmit a signal over the sidelink and receive an indication of a type of hybrid automatic repeating request (HARQ) feedback in response to the signal. The UE may then generate a radio link metric associated with the sidelink based on the type of HARQ feedback. The UE may determine that the radio link metric satisfies a predetermined threshold and initiate a keep alive procedure for the sidelink based on the radio link metric satisfying the predetermined threshold.
