International Classification:

H04W 72/04
H04B 7/06
H04L 43/0829
H04B 17/318

Abstract:

Optimal determination of wireless network pathway configurations may be provided. A computing device may establish Multi-Access Point (AP) coordination between at least a first AP and a second AP. The first AP can determine an uplink operation is scheduled. When an uplink is scheduled, the first AP can switch its antenna to a narrow beamwidth. The first AP can then receive uplink transmissions from at least a client in the coverage area of the narrow beamwidth. After the uplink transmission, the first AP can then switch the antenna to a larger beamwidth for a next Multi-AP coordination operation.

Abstract:

In one illustrative example, a device configured for use in a wireless local area network (WLAN) may cause a spatial reuse (SR) adjustment to be performed based on data received from a multi-user receiver procedure for the blind detection and demodulation of colliding packets from multiple stations. This procedure may be performed by one or more access points (APs) and/or distributed sensor nodes, each having such a multi-user receiver. The procedure may involve receiving and decoding, over a channel, a first spatial stream from a first device of a first base service set (BSS) color; simultaneously receiving and decoding, over the channel, a second spatial stream from a second device of a second BSS color (i.e. an overlapping BSS or “OBSS”); and calculating a signal-to-interference ratio (SIR) based on signal levels associated with the streams. The SR adjustment may involve adjusting an OBSS Packet Detect (PD) (OBSS-PD) threshold.
