Description
端末1aおよび基地局2aの制御部31,32は、送信データの送受信よりも前に制御情報のやり取りを行い、予め自律送信用のタイミングを規定する。端末1aの制御部31では、規定された一定時間を送信データ判断&自律送信部17に通知する。そして、送信データ判断&自律送信部17aでは、再送データを送信すると判断した場合、送信許可時間外であっても、送信要求を行うことなく、NAK信号の受信時から上記一定時間が経過した後に再送データを自律的に送信する。
このように、本実施の形態では、再送データを自律的に送信するタイミングを、NAK信号の受信時から特定の一定時間が経過した時点とすることとした。これにより、基地局はNAK信号の送信から一定時間後に再送データの受信動作を行えばよく、受信機としての機能を効率的に使用できるので、電力消費量を大幅に低減できる。
