Abstract

A radio base station apparatus comprising: a plurality of transmission antennas; an orthogonalizing section configured to orthogonalize downlink reference signals allocated to a plurality of radio resources of same frequency and different time regions, between layers by using orthogonal codes; and a transmission section configured to transmit a signal that is multiplexed with the downlink reference signals and transmission data, from the plurality of transmission antennas in multiple layers, wherein sequence information of the downlink reference signals and information of the orthogonal codes are signaled to a mobile station apparatus.
