Abstract
The SIR of the pilot symbol is calculated in channel quality estimating section 105, then, it is compared to a predetermined set threshold value. When SIR is smaller than the threshold value, the receiving data processing is stopped in receiving data processing section 107 under the control of reception processing controlling section 106. Moreover, only the pilot symbol from transmitting data processing section 110 is transmitted under the control of transmission processing controlling section 108. Therefore, it is possible to determine precisely the reliability of the communication data in packet data communication and to save the power in the data retransmission processing.
