Abstract
The LTE Multimedia Broadcast Multicast Service (MBMS) has been proven valid to support classical Vehicle-to-Anything (V2X) services such as the delivery of Cooperative Awareness Message (CAM) and Decentralized Environmental Notification Message (DENM). However, with its current specification, MBMS cannot guarantee the challenging latency and reliability requirements imposed by 5G V2X services. To decrease the communication latency, we study a solution based on the location of V2X servers and MBMS functionalities in the base stations. Several signaling mechanisms used to coordinate V2X servers of neighbor base stations in this solution are presented and analyzed in this work. The analysis shows that a periodical sharing of location information between neighbor servers can be the best option to reduce the traffic load between servers. Concerning the end - to-end latency, analytical and simulation results, based on the use of Single-Cell Point-to-Multipoint (SC-PTM) transmission, show that the localization of functions can substantially reduce the latency of conventional MBMS and ensure the correct operation of more demanding 5G V2X services, such as cooperative collision avoidance.
