Abstract: Systems and methods of providing V2X communications are generally described. The multimode UE communicates V2X messages with an eNB. The eNB detects whether the UE is able to receive messages from a nearby DSRC RSU based on measurements received from the UE and reported to the eNB. Based on the measurements, the eNB offloads V2X traffic to the DSRC RSU and triggers the UE to start communicating the V2X services from the DSRC RSU rather than the eNB. The measurements are reported in a BSR or DSRC MAC control element or RRC measurement report. The measurement report includes DSRC presence fields, CCH measurements and SCH measurements for each DSRC RSU that the UE is able to detect.

Abstract: Systems and methods of providing a V2X communications are generally described. A geographically-limited, operator-independent mapping table is used that maps between groups of V2X applications each associated with a different application category and a different RAT preferred for the V2X application category. Each grouping is based on fulfillment of one or more KPIs for the associated V2X application category. Multiple RATs are prioritized if able to fulfill the KPIs. The mapping table is modified based on the RATs supported by the V2X UE. Carrier aggregation is used when simultaneous transmission on different RATs is desired.
