Summary:To efficiently transmit and receive data frames by minimizing an influence exerted in a case in which an interference signal is generated.SOLUTION: A radio communication system comprises: adjusting means which performs transmission and reception of data frames among two or more nodes (3-2, 3-5, etc.) arranged from a gathering control station CS2 as a root, and can adjust an intermittent standby period of a super-frame, a communication period having an end point of time set to include a time zone of transmission and reception of the data frames from a start point of time of the super-frame, and an offset period corresponding to a time difference between the start time and reference time of the super-frame having earliest start time after previously set reference time; and communication time zone specifying means which specifies a communication time zone on a time base of an interference signal when the interference signal is specified. The adjusting means adjusts, based upon a communication time zone of the interference signal specified by the communication time zone specifying means, at least one of the intermittent standby period, the communication period, and the offset period.SELECTED DRAWING: Figure 1 【課題】干渉信号が発生するケースにおいても受ける影響を最小限に抑え、データフレームの送受信を効率的に行う。【解決手段】無線通信システムは、収集制御局CS2を根として2以上に亘り配置されたノード(3−2、3−5等)間のデータフレームの送受信を行い、スーパーフレームの間欠待受周期と、スーパーフレームの開始時点からデータフレームの送受信の時間帯を含むように終了時点が設定された通信期間と、予め設定された基準時刻以降で開始時刻が最早となるスーパーフレームにおける開始時刻と基準時刻との時間差に相当するオフセット期間をそれぞれ調整可能な調整手段と、干渉信号を特定した場合には干渉信号における時間軸上の通信時間帯を特定する通信時間帯特定手段とを備える。調整手段は、通信時間帯特定手段により特定された干渉信号の通信時間帯に基づいてスーパーフレームの間欠待受周期、通信期間、オフセット期間の何れか1以上を調整する。【選択図】図1
