Classification: CPC G  H | IPC G  H

Claim 8:
9. The method of claim 8, wherein the first communication message comprises first synchronization information indicating a first sending time range, wherein the first sending time range indicates a first time window within which the first vehicle sends the first carrier signal, wherein a second receiving time range and a second sending time range are configured in the radar device, wherein both the second receiving time range and the second sending time range are within a second time gap within which the radar device sends second radar signals in second adjacent periods, wherein a fixed time interval is between the second receiving time range and the second sending time range and is a positive number greater than zero, wherein the second receiving time range indicates a second time window within which the radar device receives the first carrier signal, wherein the second sending time range indicates a third time window within which the radar device sends a second carrier signal to the first vehicle, wherein the second carrier signal is a response to the first carrier signal, and wherein the method further comprises:
adjusting the second receiving time range using a microcontroller unit (MCU) of the radar device after obtaining the first communication message, wherein the second receiving time range is synchronized with the first sending time range, and wherein a second duration of the second receiving time range is consistent with a first duration of the first sending time range; and
returning the second carrier signal to the first vehicle within the second sending time range using a transmit antenna of the radar device, wherein the second carrier signal carries a second communication message that is a response to the first communication message.
