Abstract
In accordance with a method for distributed beamforming based on carrier to caused interference, a base station may receive channel state information from users. The base station may select a codeword from a codebook. The codeword may be selected so as to maximize a utility function that is based on a signal-to-caused-interference-plus-noise ratio. The base station may use the codeword for beamforming.
