PROBLEM TO BE SOLVED: To appropriately judge the reliability of communication data in packet data communication, and to reduce power consumption in a data retransmission processing. SOLUTION: An SIR of a pilot symbol is calculated at a line quality estimating part 105 and compared with a preset threshold. When the SIR is less than the threshold, a received data processing in a received data processing part 107 is stopped by control of a reception processing control part 106. In addition, only the pilot symbol is transmitted from a transmitted data processing part 110 by control of a transmission processing control part 108. |
