The transmission control part receives an input signal(210) from the external and controls packet data transmission using internal control signals. The control channel creation part creates a control channel to transmit control information for packet data according to the control of the transmission control part. Under the control of the transmission control part, the control indication channel creation part creates a control indication channel to indicate whether to transmit the control channel. The data channel creation part creates a data channel under the control of the transmission control part. The multiplexing part receives the control channel, the control indication channel, the data channel, and other channel signals to be transmitted and effectively executes multiplexing for them. The transmission part outputs the multiplexed channels through an output signal(280).
