Dynamic Offloading of V2X Services to DSRC

An apparatus of a cellular roadside unit (RSU), the apparatus comprising:

• a processor configured to cause the cellular RSU to:
• receive, from respective dedicated short range communication (DSRC) RSUs of a plurality of DSRC RSUs:
• respective capability information of the respective DSRC RSU;
• respective loading of the respective DSRC RSU;
• and
• configuration information of the respective DSRC RSU;
• establish communication with a user equipment device (UE);
• receive, from the UE, location information of the UE;
• determine to offload the UE to a first DSRC RSU of the plurality of DSRC RSUs, wherein the determination to offload the UE to the first DSRC RSU is based on:
• the location information of the UE;
• and
• the capability information and loading of the first DSRC RSU;
• and
• transmit, to the UE, an offload command including the configuration information of the DSRC RSU.

An apparatus of a dedicated short range communication (DSRC) roadside unit (RSU), the apparatus comprising:

• a processor configured to cause the DSRC RSU to:
• provide, to a cellular RSU, configuration information of the DSRC RSU;
• receive, from the cellular RSU, information about a user equipment device (UE) to be offloaded to the DSRC RSU, wherein the information includes an indication of a first vehicle-to-anything (V2X) service to be offloaded;
• and
• in response to the indication of the first V2X service to be offloaded:
• determine to accept the first V2X service, wherein the determination is based on at least one of:
• a determination that the DSRC RSU supports the first V2X service;
• or
• loading of the DSRC RSU;
• and
• transmit, to the cellular RSU, an indication that the first V2X service is accepted.

An apparatus of a user equipment device (UE), the apparatus comprising:

• a processor configured to cause the UE to:
• establish communication with a cellular roadside unit (RSU);
• detect an event;
• in response to the event, transmit, to the cellular RSU:
• location information of the UE;
• and
• a measurement report based on at least one measurement of a dedicated short range communication (DSRC) RSU;
• receive, from the cellular RSU, an offload command including configuration information of the DSRC RSU;
• and
• in response to the offload command:
• synchronize with the DSRC RSU using the configuration information;
• and
• exchange data with the DSRC RSU.
