Abstract

A wireless local area network (WLAN) includes at least one high throughput-enabled access point (AP) and at least one high throughput-enabled station (STA). A STA and a target AP communicate high throughput-related information and the STA performs a basic service set (BSS) transition to the target AP based on the high throughput-related information. The high throughput-related information may be included in an IEEE 802.11r, 802.11k, or 802.11v signaling message. The STA may send measurement reports for an extended range and a normal range of an AP separately, or may send a combined measurement report for an extended range and a normal range of an AP. A network management entity may obtain current status information of the STA and the AP regarding high throughput capabilities, features and parameters and selectively enable and disable at least one of the high throughput capabilities, features and parameters of the STA and the AP.

Description

technical field [0001] The present invention relates to a wireless local area network (WLAN). More particularly, the present invention relates to a method and system for an enhanced Basic Service Set (BSS) for a high throughput WLAN system. Background technique [0002] The IEEE 802.11r modification to the IEEE 802.11 WLAN standard describes fast Basic Service Set (BSS) transitions. The purpose of the IEEE 802.11r modification is to minimize the amount of time the data connection is lost between the station (STA) and the distribution system (DS) during BSS transition. According to IEEE802.11r modification, STA can establish security and quality of service (QoS) in new AP through minimum connection loss with DS. [0003] IEEE 802.11r defines three phases for the BSS transition from the current AP to the new AP. During the recovery phase, the STA locates and determines which AP it will attempt to transfer. The IEEE 802.11r BSS Transition Service provides a mechanism for ST...
