    摘要： The present invention is to provide each communication station with a transmission prioritised period without any useless latency in an ad-hoc communication environment including no control station. For this end, each communication station periodically transmits the beacon signal and acquires the transmission prioritised period immediately after transmission of the beacon. If the number of communication stations in the network is small, a communication station transmit a supplementary beacon within the super frame period, thereby effectively shortening the beacon interval and reducing latency at the start of transmission. At the time when a new communication station enters the network, the supplementary beacon is released in order to accommodate such new communication station.
