Patent attributes
Some of the present implementations provide a method for a first user equipment (UE) to exchange sidelink packets with at least a second UE. The method receives, through a first interface and via a radio resource control (RRC) signaling, a sidelink configuration from a first base station during a handover procedure of the first UE to a second base station. The method then exchanges, through a second interface, one or more sidelink packets with the second UE based on the sidelink configuration received from the first base station and previously stored sidelink configuration at the first UE. The first interface is configurable to be one of a long term evolution (LTE) Uu interface and a new radio (NR) Uu interface, and the second interface is configurable to be one of an LTE proximity service (ProSe) sidelink PC5 interface and an NR ProSe sidelink PC5 interface.
