摘要： In a wireless communication system based on an OFDM technology, a control channel and a low-speed data channel can be multiplexed without a reduction in the transmission speed of a traffic channel. In a communication system that is operated by multiplexing a traffic channel for performing high-speed data transmission and a control channel for performing low-speed control information transmission, an OFDM signal for transmitting the traffic channel and an OFDM signal for transmitting a control signal are multiplexed for transmission. In a receiving station, the control channel is first demodulated/decoded and a judgment is made as to whether or not any signal addressed to the self station is contained in a traffic channel signal. When any signal addressed to the self station is contained, the control channel signal is cancelled from the reception signal in accordance with a wireless channel quality and the traffic channel is demodulated.

摘要： A communication system includes a unicast base station device, a multicast base station device, and a mobile station device. Before receiving information concerning a multicast service, the mobile station device transmits, to a position register server, identification information identifying a reception area in which a multicast service is provided. When receiving incoming call information indicating that information concerning a unicast service has been received, the multicast base station device transmits the incoming call information to the mobile station device. The mobile station device receives the incoming call information even while receiving the information concerning the multicast service.
