<p>The system enables a frame which has caused a code error in CDMA transmission to be retransmitted without lowering the transmission capacity. This is done by sending the retransmitted frame R via a retransmission channel 7 which is different to the channel 3 for normal transmission information T. Code errors result in retransmission requests RQ being returned to the transmitting apparatus 10 from the receiving apparatus 20,Fig.2 (not shown).</p> |
