摘要 |
A transmission apparatus which attempts improvement of signal quality in an uplink and a downlink carries out radio transmission of different signals simultaneously from respective ones of a plurality of antennas. The apparatus has pilot multiplexing means for multiplexing a pilot channel to transmit from each antenna in one or more of a time division multiplexing method, a frequency division multiplexing method and a code division multiplexing method, data multiplexing means for time-multiplexing a pilot channel and a data channel, and means for transmitting a signal in a least one of a space division multiplexing (SDM) method and a space time transmission diversity (STTD) method.
