<p>Line condition notifying information of a down channel (206) is transmitted as a feedback signal to the destination station while permitting a lowered transmission efficiency of an up channel (202). While the radio line condition of the down channel (206) is poor, the destination station temporarily delays data transmission on receiving the line condition notifying information, thereby preventing unnecessary retransmission and easing channel contention. Data transmission is resumed when the line condition of the transmission line (206) returns to normal.</p> |
