摘要： A communication system includes a plurality of communication apparatuses that each uses CCH and a plurality of SCH to carry out communication. The plurality of communication apparatuses includes a master communication apparatus, a first slave communication apparatus, and a second slave communication apparatus. The master communication apparatus transmits SCH information that indicates the SCH that the master communication apparatus itself is using to the first slave communication apparatus; the first slave communication apparatus, when carrying out switching to the SCH that is indicated by the SCH information for communication with the master communication apparatus during communication with the second slave communication apparatus, transmits to the second slave communication apparatus channel switching information indicating that it will carry out switching to the SCH indicated by the SCH information; and the second slave communication apparatus carries out switching to the SCH indicated by the SCH information based on the channel switching information.

摘要： Each of a plurality of wireless communication apparatuses determines a factor that indicates wireless communication congestion and compares the factor that indicates wireless communication congestion with a predetermined first threshold value. Each wireless communication apparatus then judges, by means of transmission power set values that are received from other wireless communication apparatuses, whether the transmission power of the wireless communication apparatuses is at the same level as or at a lower level than that of its own wireless communication apparatus. The wireless communication apparatus lowers the transmission power set value by one level when the transmission power of other wireless communication apparatuses is at the same level as or at a lower level than that of its own wireless communication apparatus and when the factor that indicates wireless communication congestion exceeds a first threshold value.

摘要： Provided is a communication device mounted in a vehicle or disposed at the roadside, which can adaptively and efficiently manage positional information relating to directly communicable surrounding in-vehicle communication devices and surrounding roadside communication devices and can stably transmit information to a specified communication destination even when the positional relationship between vehicles frequently changes. The communication device is provided with a surrounding communication device information table for holding positional information relating to other communication devices received from the other communication devices and receipt times and a transmission destination determination unit for, when transmission destination position/area information indicating the position or area of a communication device that is a communication destination is accepted, determining a communication device with which communication is to be established on the basis of the transmission destination position/area information and the contents held in the surrounding communication device information table and making a transmission destination setting signal.
