Zusammenfassung:To provide a wireless communication terminal that is highly likely to satisfy a delay characteristic, which is a time allowed for delay, when information is relayed.SOLUTION: In a wireless communication system, a first wireless communication terminal wirelessly communicates with a second wireless communication terminal via a first wireless link by setting a first reception waiting period, and wirelessly communicates with a third wireless communication terminal via a second wireless link by setting a second reception waiting period different from the first reception waiting period. The first wireless communication terminal performs wireless communication via the first wireless link by setting a third reception waiting period waiting for transmission of information toward a downlink direction from the second wireless communication terminal, which is part or all of a period different from the first reception waiting period and the second reception waiting period, and the second wireless communication terminal does not wait for transmission of information toward an uplink direction from the first wireless communication terminal in the third reception waiting period.SELECTED DRAWING: Figure 2 【課題】情報を中継する際に、遅延してよい時間である遅延特性を満たす可能性が高い無線通信端末を提供する。【解決手段】無線通信システムにおいて、第1の無線通信端末は、第1の無線リンクを介して第2の無線通信端末と第1の受信待ち期間を設定して無線通信を行い、第2の無線リンクを介して第3の無線通信端末と第1の受信待ち期間とは異なる第2の受信待ち期間を設定して無線通信を行い、第1の無線通信端末は、第1の無線リンクを介して、第1の受信待ち期間及び第2の受信待ち期間とは異なる期間の一部又は全部であって、第2の無線通信端末からの下り方向への情報の送信を待ち受ける第3の受信待ち期間を設定して無線通信を行い、第3の受信待ち期間において、第2の無線通信端末は、第1の無線通信端末からの上り方向への情報の送信は待ち受けない。【選択図】図2
