Title: (EN) RADIO BASE STATION APPARATUS AND RADIO COMMUNICATION METHOD
Abstract: front page image
(EN)

A radio base station apparatus and radio communication method are provided whereby reception characteristics do not deteriorate even when the number of multiplexed users of an uplink control channel signal is increased. The radio communication method of the present invention includes a transmission step of a mobile terminal apparatus transmitting an uplink control channel signal orthogonally multiplexed among users including reference signals, a receiving step of the radio base station apparatus receiving the uplink control channel signal and a demodulation step of demodulating the uplink control channel signal using maximum likelihood detection.
