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. ## Claims ### Claim 1 An apparatus of a cellular roadside unit (RSU), the apparatus comprising: at least one interface to communicate with a vehicle-to-anything (V2X) user equipment (V2X UE) and a dedicated short range communication (DSRC) RSU;
