FIELD: information technology. ^ SUBSTANCE: radio communication base station includes an error detection unit which detects errors by checking uplink data, generates a first response signal for initial transmission data and a second response signal for retransmission data, and determines, initially and repeatedly through the transmitted data the addressed response signal. The radio communication mobile station includes a reception unit which receives a first response signal for initial transmission data and a second response signal for retransmission data and a demodulation unit. ^ EFFECT: during ARQ request, when multiple mobile stations divide and share one channel for response signals, a radio communication base station can reject ARQ request management. ^ 6 cl, 29 dwg |
