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