1. A method comprising:
receiving, by a first access point and from a second access point, an indication of a second beamforming codebook, associated with the second access point, comprising a plurality of beamforming matrixes;
receiving, by the first access point and from the second access point, at least one first frame indicating at least one index associated with a subset of beamforming matrixes of the plurality of beamforming matrixes; and
transmitting, by the first access point and to at least one device, at least one second frame using one or more first beamforming matrixes selected, by the first access point, based on the at least one index associated with the subset of beamforming matrixes of the plurality of beamforming matrixes.
