Abstract—IEEE 802.11k is an extension of the IEEE 802.11 specification for radio resource measurements. In an IEEE 802.11k-enabled wireless LAN, an access point or other network element may request from a client or another access point to monitor and report the load of a channel. We call the latter a channel monitoring station. In this paper we propose a mechanism for a channel monitoring station to efficiently derive accurate values of channel load.We especially focus on optimizing the duration of channel monitoring and thus minimize the impact on applications. Note that such mechanisms are critical for the success of new sharing regimes such as Cognitive Radio and Open Spectrum Access.

IEEE802.11 工作组近年来开始定义新的物理层标准IEEE802.11ｇ。与以前的IEEE802.11 协议标准相比，IEEE802.11ｇ草案有以下两个特点：在2．4 GHz频段使用正交频分复用（OFDM）调制技术，使数据传输速率提高到20 Mbit/s 以上；能够与IEEE802.11ｂ的Wi-Fi 系统互联互通，可共存于同一AP 的网络里，从而保障了后向兼容性。这样原有的WLAN 系统可以平滑地向高速WLAN 过渡，延长了IEEE802．11b产品的使用寿命，降低了用户的投资。2003 年7 月IEEE802.11 工作组批准了IEEE802.11ｇ草案，该标准成为人们关注的新焦点。
