To efficiently perform data transmission from a wireless terminal station with low delay in a TDMA wireless communication system.SOLUTION: In a wireless terminal station that transmits an allocation request signal for allocating a wireless terminal station to an information data channel MDC of an information data slot MDTS by a TDMA wireless communication, at least one allocation request transmission slot ACTS is included in one frame of TDMA wireless communication, and an allocation request transmission channel ACC and an allocation request response channel AC-AKC are included in an allocation request transmission slot ACTS, and when the allocation request signal is transmitted from the wireless terminal station via the allocation request transmission channel ACC, and no response signal to the allocation request signal is received from a base station via the allocation request response channel AC-AKC, the allocation request signal is retransmitted from the wireless terminal station via the subsequent allocation request transmission channel ACC.SELECTED DRAWING: Figure 3 【課題】ＴＤＭＡ無線通信システムにおいて、無線端末局からのデータ伝送を低遅延で効率よく行うことを可能にする。【解決手段】ＴＤＭＡ方式の無線通信によって、情報データスロットＭＤＴＳの情報データチャネルＭＤＣに無線端末局を割り当てるための割り当て要求信号を送信する無線端末局において、ＴＤＭＡ方式の無線通信の１つのフレームに、少なくとも１つの割り当て要求伝送スロットＡＣＴＳを含み、割り当て要求伝送スロットＡＣＴＳには、割り当て要求送信チャネルＡＣＣおよび割り当て要求応答チャネルＡＣ−ＡＫＣを含み、割り当て要求送信チャネルＡＣＣを介して、無線端末局から割り当て要求信号を送信し、割り当て要求応答チャネルＡＣ−ＡＫＣを介して、基地局から割り当て要求信号に対する応答信号を受信しない場合には、後続の割り当て要求送信チャネルＡＣＣを介して、無線端末局から割り当て要求信号を再送信する。【選択図】図３
