If so, the terminals(11-14) consider that other terminals occupy a wireless channel, and transmit packet data, then feed back to the step of sensing the power control signal. If the power control signal is not sensed, the terminals(11-14) transmit a preamble signal of repeating "0" for predetermined time to a base station(20) through a wireless channel. After transmitting the preamble signal, the terminals(11-14) transmit packet data to be transmitted to a base station(20).
