Abstract
A radio communications apparatus is disclosed which includes a generator which generates a transmit frame; and a transmitter which transmits the transmit frame via multiple transmit antennas. In the radio communications apparatus, the transmit frame includes a predetermined number of resource elements having a predetermined frequency bandwidth and a predetermined symbol period, and the generator generates the transmit frame such that the number of transmit antennas which are identifiable from a location of the resource element taken up by a pilot signal in a certain transmit frame is less than the number of transmit antennas which are identifiable from the location of the resource element taken up by the pilot signal in a retransmission transmit frame of the certain transmit frame.
