Abstract
A communication system includes a roadside unit and a mobile communication unit that communicates with the roadside unit by using one of a plurality of communication channels. The mobile communication unit obtains, for each communication channel, a reception condition measurement representing the reception condition of a radio signal received from the roadside unit, creates information of a candidate channel for a receiving channel to be used to receive the radio signal from the roadside unit, and reports the candidate channel information to the roadside unit. On the other hand, the roadside unit assigns the receiving channel by selecting it from among the candidate channels, and reports the receiving channel to the mobile communication unit.
