Abstract:
A method includes calculating a set of first metrics using channel information and one or more precoders, where each of the first metrics corresponds to a respective set of a plurality of sets of codebook precoders, and selecting, based on the set of first metrics and a first selection criteria, a set of codebook precoders from the plurality of sets of codebook precoders. The method also includes, in response to selecting the set of codebook precoders, calculating a set of second metrics and selecting, based on (i) the set of second metrics and (ii) a second selection criteria, a codebook precoder from the selected set of codebook precoders. Each of the second metrics is calculated using a respective codebook precoder in the selected set of codebook precoders. The method also includes causing the selected codebook precoder to be applied to a signal to be transmitted to a communication device.
