USING SIDELINK BETWEEN VEHICLE-MOUNTED RELAYS TO OPTIMIZE USER EQUIPMENT MOBILITY

Abstract:

Techniques and apparatus for using sidelinks for communications between vehicular mounted relays to improve user equipment (UE) mobility are described. In one technique, a first vehicle relay can receive information from a second vehicle relay via a sidelink. The information includes at least one of a location, a speed, or a direction of the second vehicle relay. The first vehicle relay determines to handover a UE served by the first vehicle relay to the second vehicle relay, based at least on the information, and triggers a handover of the UE to the second vehicle relay, in response to the determination. In another technique, a base station may receive the information from the first vehicle relay via radio resource control signaling, determine to handover the UE to the second vehicle relay, based at least on the information, and trigger a handover of the UE, in response to the determination.
