The total amount of power for communications transmitted over channels susceptible to quality fluctuation is decreased to reduce the interference with the other communications and increase the system's overall capacity. When channel-encoded data is to be transmitted, the quality of a transmission channel is judged. The data is transmitted when the judged quality is higher than predefined. However, if the quality is lower than predefined, the data transmission to a wireless section is suppressed to avoid a signal transmission that cannot effectively be used at a receiving station, decrease the average transmission power, and reduce the interference with the other communications. Even if the channel quality is lower than predefined at the time of assigning a code word created by channel encoding, the same code word assignment operation as for a transmission portion is performed with respect to a no-transmission portion that a transmitting station does not send to a wireless section. This ensures that when the channel code is decoded at a receiving station, the receiving station can accomplish its reception without having to know which portion was not sent to a wireless section. |
