COMBINED COORDINATED SPATIAL REUSE, BEAMFORMING, AND NULLING TO INCREASE SPECTRAL EFFICIENCY IN HIGH-DENSITY WIRELESS NETWORKS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240381110 titled 'COMBINED COORDINATED SPATIAL REUSE, BEAMFORMING, AND NULLING TO INCREASE SPECTRAL EFFICIENCY IN HIGH-DENSITY WIRELESS NETWORKS
Abstract: Spectral efficiency in dense multi-access point wireless networks is improved by combining coordinated spatial reuse and coordinated beamforming/nulling schemes. Access points are classified as sharing or shared based on medium access control, and stations are categorized into largest and smallest coordination gain areas. Coordinated spatial reuse is applied to non-overlapping stations in a small coordination gain area, while coordinated beamforming/nulling is used for overlapping stations in a largest coordination gain area. The shared access point adjusts its transmit power to minimize interference. Channel state information feedback overhead is reduced by considering only links related to the largest coordination gain area. The proposed method increases spectral efficiency, reduces overhead, and enhances coverage compared to using coordinated spatial reuse or coordinated beamforming/nulling alone.
