Abstract: The hidden node problem can be avoided by scheduling stations in different sectors to perform transmissions during different time periods. Sectorized scheduling can be communicated to stations through transmission of beamformed beacon signals at the beginning of respective time periods. For instance, a first beamformed beacon signal may be transmitted to stations in a first sector at the beginning of a first time period, while a second beamformed beacon signal may be transmitted to stations in a second sector at the beginning of a second time period.

Abstract: A method for beamforming training is disclosed including SNR values with each of the SNR values associated with one of the antenna identifiers (IDs) in a first frame identifying different radio frequency (RF) chains for a process of beamforming training; receiving and transmitting the first frame bi-directionally between multiple pairs of communicating nodes, wherein each pair of the communicating nodes has at least one initiator node and one responder node; receiving feedback of the SNRs associated with the antenna IDs from two or more responder nodes of the multiple pairs of the communicating nodes to choose an RF chain as favorable transmit antenna for transmission; and determining respective one from the multiple antenna sectors of the multiple antennas for transmission for the responder nodes according to the feedback. A central network controller and a system are also disclosed herein.

Abstract: Mobile stations can query independent basic service set (BSS) parameters of a group of Access Points (APs) by setting a Pre-Association Message Exchange BSSID Independent (PAME-BI) bit during Wi-Fi discovery. The PAME-BI bit may be included in a Generic Advertisement Service (GAS) request to indicate that an Access Network Query Protocol (ANQP) request carried by the GAS request is querying both independent and dependent BSS parameters. In some embodiments, the PAME-BI bit is included as a field in the ANQP query, rather than the GAS request message.

Abstract: In one embodiment, a method includes receiving, by a station (STA) from an access point (AP), a frame including a device type indicator and comparing the device type indicator with a device type accepted by a basic service set (BSS) of the AP to produce a comparison. The method also includes determining whether to associate the STA with the AP in accordance with the comparison, associating the STA with the AP upon determining to associate the STA with the AP, and not associating the STA with the AP upon determining not to associate the STA with the AP.
