Abstract:
A multi-cell/multicast coordination entity (MCE) determines a cluster to which a vehicle-to-everything (V2X) message. The MCE receives a first session start message, which includes a temporary mobile group identity (TMGI), quality of services (QoS) parameters, and a list of cells, from a V2X application server and determines a cluster, which contains group of cells, to which V2X message is to be broadcast, based on the received TMGI, QoS parameters, and list of cells. Upon determining the cluster, the MCE transmits a second session start message, which includes an indication to notify eNodeB (eNB) to wait for scheduling information, to eNBs corresponding to the determined cluster, and transmits MBMS scheduling information to the eNBs. Further, update of the cluster may be triggered from the V2X application server or from the eNB with limited feedback.
