Assignee: QUALCOMM INCORPORATED
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 9:
10. A device for determining an alternative communication mode for vehicle-to-vehicle communication at a host vehicle, the device comprising:
a first transceiver configured to be used in a primary radio frequency (RF) communication mode by the host vehicle for vehicle-to-vehicle communication;
a second transceiver configured to be used in one or more alternative communication modes alternative to the primary RF communication mode;
a memory; and
a processing unit communicatively coupled with the first transceiver, the second transceiver, and the memory, wherein the processing unit is configured to:
monitor signals of the primary RF communication mode used by the host vehicle for vehicle-to-vehicle communication;
determine, based at least in part on the monitoring, that a density of vehicles has exceeded a threshold density value;
responsive to the determining that the density of vehicles has exceeded the threshold density value, select, from one or more alternative communication modes alternative to the primary RF communication mode, a second RF communication mode with which to send a vehicle-to-vehicle message; and
send, from the host vehicle, the vehicle-to-vehicle message via the second RF communication mode using the second transceiver.
