PROBLEM TO BE SOLVED: To secure a road-to-road communication period during a road-to-vehicle communication period.SOLUTION: A road-side communication apparatus 2 includes a control unit for controlling to transmit downlink data to a vehicle in a road-to-vehicle communication period allocated to the own apparatus. The downlink data may include static information and dynamic information. In a first road-to-vehicle communication period, the dynamic information and the static information are transmitted as the downlink data. In a second road-to-vehicle communication period, the dynamic information is transmitted as the downlink data without transmission of the static information. A portion of a period in the second road-to-vehicle communication period in which a temporal margin is produced because of not transmitting the static information is secured as a period for other purposes to be used for road-to-road communication or the like.SELECTED DRAWING: Figure 5

    【課題】路車間通信期間中に路路間通信期間を確保する。【解決手段】本発明は、自機に割り当てられた路車間通信期間において車両に対するダウンリンクデータを送信する制御を行う制御部を備えた路側通信機2に関する。ダウンリンクデータは、静的情報と、動的情報と、を含み得るものである。第1路車間通信期間では、ダウンリンクデータとして動的情報及び静的情報が送信される。第2路車間通信期間では、ダウンリンクデータとして前記静的情報を送信せずに前記動的情報が送信される。静的情報を送信しないことで時間的余裕のある第2路車間通信期間における一部の期間が、路路間通信などに用いられる他目的期間として確保される。【選択図】図5
