Document Type and Number:
Japanese Patent JP3471785
Kind Code:
B1
Abstract:
Confidence calculator 211 finds confidence based on the measurement result of the received SIR. Based on the confidence supplied from confidence calculator 211 , ACK/NACK decider 212 makes a decision for the then modulated ACK signal with reference to a predetermined threshold level. For the ACK/NACK decision result, scheduler 251 instructs buffer 252 to transmit new data when an ACK signal is received, and to transmit the data of the previous transmission when a NACK signal is received. By this means, it is possible to prevent loss of the received data in the communication terminal apparatus that occurs when a NACK signal is erroneously received and the data is not retransmitted from the associated communication terminal apparatus.
