In one aspect, a method includes receiving, by an access point a mes- sage including a beamforming report from a device. The device may be a sta- r 510a tion that is outside a basic service set of the access point. The method also in- cludes transmitting a message to the device based on the beamforming report. For example, in some aspects, the access point may utilize the beamforming report to perform a coordinated beamforming, multi-access point transmis- sion or a multi-access point MIMO transmission. In some aspects, the access point may transmit an interference nulling signal to the device based on the beamforming report. The nulling signal compensates for another simultaneous transmission by the access point that interferes with the device's reception of a message from an access point with which the device is associated.
