摘要

A transmission station performs carrier sense for a predetermined time and sends a request to send (RTS) signal to the partner station. When a clear to send (CTS) signal is received from the partner station within a predetermined waiting time Tw, the transmission station waits for the AGC rise time and transmits the first packet comprised of a data portion and a header portion containing a synchronization signal (SYNC) and an ID signal. Next, the transmission station continuously transmits the second packet. The header portions of the subsequent packets contain only synchronization signals. With this arrangement, when a plurality of transmission stations want to transmit image data by radio using asynchronous TDMA, image data for one picture can be transmitted in a short time without interruption.
