Problems solved by technology

In many deployments APs on the same radio channel are within CCA range of each other; thus, an AP may be blocked from transmitting to its client STA due to activity of a neighboring nearby AP.

Abstract

A method of one AP accessing a channel occupied by a neighboring AP within CCA range, by acquiring channel knowledge via performing cooperative sounding and setting a null towards the neighboring AP, under certain conditions verifications, is provided herein. The method may include: transmitting and receive signals via a plurality of radio circuitries connected to plurality of antennas; monitoring signals received by the radio circuitries and generating a list of neighboring co-channel access points that each has plurality of antennas and are further located within a clear channel assessment (CCA) range of the access point; and instructing the radio circuitries to transmit a sounding sequence to the list of neighboring access points, and receive Channel State Information (CSI).

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation application of U.S. patent application Ser. No. 14 / 449,431 filed on Aug. 1, 2014, which claims benefit from U.S. Provisional Patent Application Ser. No. 61 / 955,433 filed on Mar. 19, 2014, all of which are incorporated herein by reference in their entirety.FIELD OF THE INVENTION[0002]The present invention relates generally to wireless communication, and more specifically to high efficiency Wi-Fi.BACKGROUND OF THE INVENTION[0003]Prior to setting forth the background of the invention, it may be helpful to set forth definitions of certain terms that will be used hereinafter.[0004]The term “Wi-Fi” as used herein is defined as any wireless local area network (WLAN) products that are based on the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standards.[0005]The term “Access Point” or “AP” as used herein is defined as a device that allows wireless devices (also known as User Equipment or “UE”) ...
