US 11,963,021 B2 · Adaptive spatial reuse

Abstract

Systems and methods are provided for adaptively enabling and disabling spatial reuse and adapting BSS color assignments based on various factors associated with a wireless network. A first AP in a wireless network can identify a second AP in a wireless network. The first AP and the second AP may be using the same wireless channel in the wireless network. The first AP can determine a signal strength, such as a received signal strength indicator (RSSI), associated with the second AP. The first AP can adapt its spatial reuse and BSS color assignment according to the signal strength and a signal strength threshold. By adaptively enabling and disabling spatial reuse and adapting BSS color assignments, the disclosed systems and methods provide for improved reuse of wireless mediums while avoiding collisions.

Dependent claims

A method comprising:

identifying, by a first access point (AP), a second AP based on an identifier associated with the second AP;
determining, by the first AP, a signal strength associated with the second AP;
determining, by the first AP, a basic service set (BSS) color assignment based on the signal strength of the second AP and a signal strength threshold by:
selecting, by the first AP, a BSS color assignment that matches a BSS color assignment associated with the second AP based on the signal strength of the second AP exceeding the signal strength threshold;
or
selecting, by the first AP, a BSS color assignment that differs from a BSS color assignment associated with the second AP based on the signal strength of the second AP being within the signal strength threshold;
and
transmitting, by the first AP, a data frame based on the BSS color assignment.
