In a wireless communication system and a firmware update method of a wireless communication terminal station in the system, firmware can be safely downloaded and updated through wireless communication without affecting user's ordinary data communication. The CPU executes arithmetic control processing for various types of data. For example, the CPU controls the data conversion achieved by an high-layer interface. Specifically, to send data from the wireless LAN card to the mobile terminal, the CPU controls conversion processing for the high layer. Conversely, when the mobile terminal sends data to the wireless LAN card, the CPU controls the conversion for the low layer. The CPU also reads and executes a firmware program recorded in one of the memories. The CPU refers to the boot information memory and determines from which one of the memories the firmware is to be read. At firmware update, the CPU determines in which one of the memories data is to be written.

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.
