RADIO COMMUNICATION METHOD AND RADIO COMMUNICATION DEVICE

摘要

when the SC-FDMA method is used in combination with the multi-antenna transmission technique, a radio transmission method effectively improves the frequency use efficiency by performing appropriate frequency allocation to a plurality of antennas while suppressing degradation of the reception quality caused by interference. In the radio transmission method of the SC-FDMA type, according to the number of terminals simultaneously accessing a base station within a usable frequency band, it is possible to allocate all the transmission signals (transmission stream) to be transmitted by different antennas to different frequency bands or to use the MIMO transmission in combination. Moreover, according to the number of terminals making an access, the number of terminals which perform the MIMO transmission can be varied.
