In a disclosed transmission apparatus (10), a control channel transmission antenna number selection control portion (12) selects the number of transmission antennas (TA) that transmit a control channel in accordance with transmission quality information received from a quality information measurement portion (23) of a reception apparatus (20). In addition, a control channel generation portion (11) generates multiplexed transmission control information obtained by multiplexing multiple pieces of transmission control information for corresponding radio signals and storing the generated multiplexed transmission control information in a control channel area of at least one of transmission frames for transmitting the information. The number of the transmission antennas (TA) that transmit the control channel is determined to be one, the maximum number of the transmission antennas, or any number between one and the maximum number. |
