<p>A MIMO communication system efficiently using radio resources for pilot signals while avoiding both inter-cell/sector interference in pilot signal transmission and interference between transmitting antennas in MIMO communication is provided. According to radio communication path quality information (413, 423) reported by means of a pilot signal from one or more receiver communication devices (51), a usable pilot signal is dynamically allocated to transmitter communication devices (31, 32) and a communication method is changed. If two or more pilot signals are allocated, MIMO communication is performed. The one or more receiver communication devices (51) change reception processing according to the radio communication path quality information, separate the combined signal from the transmitter communication devices (31, 32) by MIMO reception, and discard the interference signals from other cell/sectors.</p> |
