Vehicle-to-infrastructure communication
In one embodiment, a method includes, determining multiple data packets for transmission. The method includes generating a log that includes a sequence identifier associated with each data packet. The method includes transmitting the data packets via a first radar antenna coupled with a vehicle and associated with the computing system. The method includes receiving an acknowledgement from a second radar antenna that identifies at least one sequence identifier associated with at least one of the data packets. The method includes identifying one or more data packets that were not received by the second radar antenna by comparing the at least one sequence identifier in the acknowledgment and the sequence identifier associated with each data packet in the log. The method includes retransmitting the one or more identified data packets that were not received by the second radar antenna via the first radar antenna.
