Problems solved by technology

Given this spectrum limitation, WLAN systems may only be able to support smaller bandwidths and lower data rates than, for example, IEEE 802.11n / 802.11ac based High Throughput / Very High Throughput (HT / VHT) WLAN systems

Embodiment

[0122] CLAIMS 1. A method for wireless communication, the method comprising providing a network transition.

[0123] 2. The method of embodiment 1, wherein the number of management frames is reduced.

[0124] 3. The method as in any preceding embodiment, wherein the initial link setup time with the access point (AP) for the station (STA) is less than or equal to 100 milliseconds.

[0125] 4. The method according to any one of the preceding embodiments, wherein the initial link setup time with the AP for at least 100 STAs is less than or equal to 1 second.

[0126] 5. The method as in any one of the preceding embodiments, wherein the beacon includes information facilitating a desired initial link setup time.

[0127] 6. The method as in any one of the preceding embodiments, wherein the probe response frame is transmitted to the plurality of STAs as a broadcast frame.

[0128] 7. The method as in any one of the preceding embodiments, wherein the AP only responds to probe reque...

Abstract

A method and apparatus may be used to perform efficient network transitions. One or more of Probe Request frames that an AP may receive or process as valid may be modified by including a transmit power for the Probe Request frame. A Probe Request frame may be transmitted at less than full power. BSS transitions may be enhanced by indicating reasons for the transition, security information, or quality of service (QoS) information. Overhead associated with tracking long-sleeping STAs may be managed through the use of multiple values for a maximum idle period in a BSS.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 61 / 953,385, filed March 14, 2014, the contents of which are hereby incorporated by reference. Background technique [0003] A WLAN in infrastructure basic service set (BSS) mode may have an access point (AP) for the BSS and one or more stations (STA) associated with the AP. The AP may typically have an access or interface to a distribution system (DS) or another wired / wireless network that carries traffic to and from the BSS. Traffic originating outside the BSS to STAs may pass through the AP and be delivered to the STAs. Traffic originating from STAs to destinations outside the BSS may be transferred to the AP for delivery to the respective destinations. Traffic between STAs within a BSS may also be transmitted through an AP, where the source STA transmits traffic to the AP and the AP delivers traffic to the destination STA. Such traffic between ST...
