Publication number: 20210021377Abstract: A receiving station (3) performs first signal detection processing on a received radio signal, performs a retransmission request to a transmitting station (2) in a case in which a code error is detected in a detected radio packet for user data, and enqueues the radio packet for user data in a reception buffer in a case in which no code error is detected. In parallel with the first signal detection processing, the receiving station (3) performs second signal detection processing on the received signal with a longer processing delay than that of the first signal detection processing, and in a case in which no code error is detected in the detected radio packet for user data, the receiving station (3) enqueues the radio packet for user data in the reception buffer. The receiving station (3) outputs, at a predetermined timing, the radio packet for user data with no code error detected, the radio packet being enqueued in the reception buffer.Type: ApplicationFiled: March 19, 2019Publication date: January 21, 2021Inventors: Atsushi Ota, Naoki Kita, Yutaka Imaizumi, Satoshi Kurosaki, Kazuto Goto, Kota Ito
