Abstract
Upon receiving an uplink (UL) V2X message from a vehicle user equipment (UE) or a road side unit (RSU) UE, a vehicle-to-everything (V2X) application server determines information on resource allocation for a downlink (DL) V2X message and transmits the information on resource allocation to a multi-cell/multicast coordination entity (MCE). The MCE (for multimedia broadcast multicast services (MBMS) based resource allocation scheme) or an eNB (for single-cell point-to-multipoint (SC-PTM) resource allocation scheme) allocates resources for the DL V2X message based on the received information on resource allocation.
Claims6
A method for allocating resources for vehicle-to-everything (V2X) message transmission by a multi-cell/multicast coordination entity (MCE) in a wireless communication system, the method comprising:
- receiving information on resource allocation for a downlink (DL) V2X message from a V2X application server;
- allocating resources for the DL V2X message based on the received information on resource allocation;
- and
- transmitting a multimedia broadcast multicast services (MBMS) scheduling information message to an eNodeB (eNB) supporting V2X communication or a road side unit (RSU) supporting V2X communication,
- wherein the MBMS scheduling information message includes at least one of a physical multicast channel (PMCH) configuration, a MBMS session list per PMCH, a multicast-broadcast single-frequency network (MBSFN) subframe configuration, or a MBSFN area ID, and
- wherein the PMCH configuration, the MBMS session list per PMCH, and the MBSFN subframe configuration are an updated PMCH configuration, an updated MBMS session list per PMCH, and an updated MBSFN subframe configuration, respectively.
