DEVICE AND METHOD FOR MULTIANTENNA RADIO COMMUNICATION

摘要

PROBLEM TO BE SOLVED: To improve quality in reception and throughput in a system by using a different communication channel in retransmission for transmission in an MIMO transmission system. SOLUTION: There are provided a plurality of antennas for receiving a plurality of demodulation signals transmitted from the plurality of antennas simultaneously, a retransmission request detector for detecting a retransmission request included in a reception signal, a data selector for selecting data to be retransmitted by using the retransmission request, and a radio unit for changing the communication channel of the data to be retransmitted to the communication channel CH2 different from the previous one CH1 to transmit the data to be retransmitted.
