摘要： Conventionally, if the number of transmission antennas is greater than that of reception antennas, different signals simultaneously transmitted from the transmission antennas cannot be separated from one another at the receiving end, resulting in a significant degradation of received-signal quality. A transmitter and a receiver each have a plurality of antennas. The transmitter transmits a pilot signal. The receiver receives the pilot signal, calculates transmission-related information corresponding to the pilot signal, selects, based on this calculated information, a transmission signal to be used by the transmitter, and notifies the transmitter of the selected signal. The transmitter selects, from the informed transmission signal, transmission antennas and uses the selected antennas to transmit information signals, so that a signal separation can be easily performed at the receiving end.

摘要： In a radio communication system that simultaneously provides communication service using a plurality of discontinuous frequency bands, a multi-band radio communication method according to the present invention is a method in which a base station constituting the system allocates a band to a mobile station that requests a communication starting. For example, a specific receiving unit within the base station extracts control information concerning a channel state in each of the frequency bands, and recognizes a frequency band in which the mobile station can receive information, from a result of the extraction. A channel controller 9 determines, starting from a high frequency band, whether a new traffic responding to the communication starting request can be allocated in each frequency band.
