分类:无线标准 下载:4 浏览:292 时间:2021-01-07IEEE Std 802.16-2004 (Revision of IEEE Std 802.16-2001) IEEE Standard for Local and metropolitan area networks Part 16: Air Interface for Fixed Broadband Wireless Access Systems Approved 24 June 2004 Abstract: This standard specifies the air interface of fixed broadband wireless access (BWA) systems supporting multimedia services. The medium access control layer (MAC) supports a primarily point-to-multipoint architecture, with an optional mesh topology. The MAC is structured to support multiple physical layer (PHY) specifications, each suited to a particular operational environment. For operational frequencies from 10–66 GHz, the PHY is based on single-carrier modulation. For frequencies below 11 GHz, where propagation without a direct line of sight must be accommodated, three alternatives are provided, using OFDM, OFDMA, and singlecarrier modulation. This standard revises and consolidates IEEE Std 802.16-2001, IEEE Std 802.16a-2003, and IEEE Std 802.16c-2002. Keywords: fixed broadband wireless access network, metropolitan area network, microwave,millimeter wave, WirelessMAN® standards -

Optimizing the Channel Load Reporting Process in IEEE 802.11k-enabled WLANs
分类:无线标准 下载:4 浏览:450 时间:2021-01-07Abstract—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. -
