V2X communication device and transmission power control method thereof

摘要

A V2X communication device includes a communication unit, an occupancy time calculation unit, a power control unit. The communication unit supports communication between a vehicle and an object. The occupancy time calculation unit calculates at least one of a radio wave occupancy time, in which data is transmitted/received through the communication unit in each communication period, and a radio wave non-occupancy time, in which the data is not transmitted/received in each communication period. The power determination unit determines whether to adjust the data transmission power based on at least one of the radio wave occupancy time and the radio wave non-occupancy time, which are calculated by the occupancy time calculation unit. The power control unit adjusts and controls the data transmission power according to the determination from the power determination unit.
