To prevent other roadside communication devices from continuously failing in air synchronization.SOLUTION: In a radio communication system, a transmission time is allocated to each of a plurality of on-vehicle communication devices 3 and a plurality of roadside communication devices 2 by time division, and the roadside communication devices 2 execute air synchronization with each other. A roadside communication device 2 used in the radio communication system includes: a communication processing unit 18 for transmitting communication data to other roadside communication devices 2 by packet; and a control unit 23 for having the communication processing unit 18 transmit a packet for air synchronization executed by the other roadside communication devices 2.SELECTED DRAWING: Figure 6
【課題】 他の路側通信機がエア同期を継続的に実行できなくなるのを防止することができる。【解決手段】 複数の車載通信機3及び複数の路側通信機2それぞれに送信時間が時分割によって割り当てられているとともに、複数の路側通信機2が互いにエア同期を行う無線通信システムで用いられる路側通信機2であって、他の路側通信機2に対して通信データをパケット送信する通信処理部18と、他の路側通信機2が行うエア同期のために、通信処理部18にパケット送信させる制御部23と、を備えている。【選択図】図6
