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.

Claims27

Dependent claims

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;
and
processing circuitry in communication with the interface and arranged to:
encode data of a V2X service for transmission to the V2X UE on a cellular frequency band;
encode DSRC measurement information for transmission to the V2X UE through the interface, the DSRC measurement information comprising parameters for measurement of DSRC frequency band signals from the DSRC RSU by the V2X UE;
decode DSRC measurements from the V2X UE based on the DSRC measurement information;
determine whether to offload the V2X service to the DSRC RSU based on the DSRC measurements;
in response to a determination to offload the V2X service to the DSRC RSU, communicate offloading information with the DSRC RSU, the offloading information indicating offloading of the V2X service from the cellular RSU to the DSRC RSU;
and
after communication of the offloading information, encode an offload command for transmission to the V2X UE through the interface, the offload command comprising an indication of offloading of the V2X service from the cellular RSU to the DSRC RSU.
