PURPOSE:To improve transmission efficiency by adding an ACK function and a priority control function. CONSTITUTION:None of terminals performs transmission for a specific time (T1) after signal transmission. Only a station which receives a signal, however, transmits an ACK signal. Each terminal transmits a signal in its allotted time after the time T1. The (N)th terminal is to start transmission a time T2XN later. If the circuit is used at this time, it is to restart the transmission the next time T2XN later. Then, the station tries to restart the transmission until it succeeds in the transmission. |
