description	PROBLEM TO BE SOLVED: To improve the channel utilization efficiency of a whole system by increasing the channel utilization efficiency of a secondary channel even when the time occupancy of a primary channel for transmitting a management frame is increased.SOLUTION: In a radio LAN system, a plurality of radio LAN base stations (base stations) exist in a range where mutual radio waves are detectable, and each base station is configured to, when a predetermined primary channel is unused, transmit a management frame to be used by a radio terminal for connection processing with the base station, and to, when the primary channel is unused, transmit a data frame to be used for data communication with the radio terminal by connecting the primary channel to an unused secondary channel. The base station includes control means for transmitting one or more data frames by using the unused secondary channel in a period for transmitting the management frame.SELECTED DRAWING: Figure 2 【課題】管理フレームを送信するプライマリチャネルの時間占有率が増しても、セカンダリチャネルのチャネル利用効率を高め、システム全体のチャネル利用効率を改善する。【解決手段】互いの電波を検知できる範囲に複数の無線ＬＡＮ基地局（以下、基地局）が存在し、各基地局は、所定のプライマリチャネルが未使用のときに無線端末が該基地局との接続処理に用いる管理フレームを該プライマリチャネルで送信し、該プライマリチャネルが未使用のときに該無線端末とのデータ通信に用いるデータフレームを該プライマリチャネルと未使用のセカンダリチャネルを結合して送信する無線ＬＡＮシステムにおいて、基地局は、管理フレームを送信する期間に、未使用のセカンダリチャネルを用いて１以上のデータフレームを送信する制御手段を備える。【選択図】図２
