Embodiment Construction

[0056] In dense wireless environments, such as wireless corporate offices, outdoor hotspots, or crowded residential environments, an access point (AP) can become overloaded with traffic if it is associated with too many stations (STAs). Accordingly, methods and systems for providing and transmitting Basic Service Set (BSS) load elements in a WLAN system to improve spectral efficiency and link reliability are described below.

[0057] figure 1 A schematic diagram of a WLAN system 90 is provided in which the methods described herein may be implemented. An AP 101 together with at least one associated STA 102 is referred to as an infrastructure Basic Service Set (BSS). figure 1 Two representative BSSs 100(1), 100(2) (collectively referred to herein as BSSs 100) in a WLAN system 90 are included. An AP 101 is any entity that has STA functionality and provides associated STAs 102 with access to distribution services. As used herein, a STA 102 may be a mobile device capable of wire...

Abstract

A method and system for providing utilization information for a basic service set (BSS) in a wireless local area network system, performed by an access point, comprising generating and transmitting a BSS load element of flow unutilization field, and multiple Δ observable secondary channel utilization fields. The STA count field indicates the total number of STAs currently associated with the BSS. each of the frequency and / or space division multiplexing stream unutilization fields indicates unutilized frequency and / or space division multiplexing stream domain resources on OFDA resource units for each channel, and The unutilized field per frequency and / or SDM stream is calculated based on the RU size. Each ΔObservableSecondaryChannelUtilization field indicates the utilization of the subbands within the secondary channel calculated based on the observable utilization on the corresponding secondary channel.
