/Multi-access Point Coordinated Beamforming
Abstract

A first access point (AP) receives, from a second AP, a frame. The frame indicates a beamforming transmission by the first AP and the second AP, and an acceptable receive interference level (ARIL), at a first station (STA) associated with the second AP, of a physical layer protocol data unit (PPDU) transmitted, by the first AP to a second STA associated with the first AP, for the beamforming transmission. The first AP determines, based on the ARIL, a set of beamforming weights for the beamforming transmission. The first AP transmits, to the second STA and for the beamforming transmission, the PPDU beamformed based on the set of beamforming weights.
