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.
L'invention concerne un dispositif et un procédé permettant la transmission à la station destinataire d'une l'information indiquant l'état le la ligne dans un canal (206) descendant sous forme d'un signal de rétroaction, tout en assurant une transmission à rendement diminué dans un canal (202) montant. Lorsque l'état de la ligne radio est mauvais, la station destinataire diffère temporairement l'émission de données suite à la réception de l'information indiquant l'état de la ligne ce qui permet d'éviter des retransmissions inutiles et de réduire les conflits de canaux. La transmission des donnée est reprise dès que l'état de la ligne (206) de transmission redevient normal.
