[0042] H-ARQ applied in the present invention is a link control technique for correcting packet errors by retransmission. As obvious from the name, a resend is a resend of data that failed in the initial transmission. Therefore, no new data is sent in the retransmission.
[0043] As previously described, H-ARQ is divided into H-ARQ type II and H-ARQ type III according to whether systematic bits are retransmitted or not. Distinguished according to whether the same parity bits are retransmitted, the main H-ARQ type II is FIR and H-ARQ III includes CC and PIR.
[0044] The invention described below will be applied to all the above-mentioned H-ARQ methods. In CC, th...
