Abstract(in English) In 2012, the Association of Radio Industries and Businesses(ARIB) standardized ARIB STD-T109 for ITS radio communication systems. ARIB STD-T109 adopts Carrier Sense Multiple Access with Collision Avoidance(CSMA/CA) as an access control protocol. Although the mobile station waits until the channel is judged as idle for the distributed space and the random waiting time in order to avoid collision in CSMA/CA, the waiting time results in a degradation of the system throughput. In this paper, we focus on the periodic transmission of the ITS frame and propose a new decentralized access scheme by modifying ARIB STD-T109. Since the proposed scheme is compatible with ARIB STD-T109, it is possible to work well in several situations. By computer simulations, we show that the proposed scheme always outperforms the conventional one.
