  • Method and apparatus for performing communication in multi-stage beam forming system
    Patent number: 9356809
    Abstract: A method for performing communication in a multi-stage beam forming system includes determining statistical channel information which indicates a priority of analog beams transmitted by a base station, configuring an adaptive code book for digital beam forming, based on the statistical channel information and analog beams which the base station uses in actual communication among the analog beams, and performing communication with the base station through the digital beam forming based on the adaptive code book. A terminal includes a channel estimator configured to perform channel estimation for analog beams transmitted from a base station, a controller configure to determine statistical channel information indicating a priority of the analog beams, and configure an adaptive code book for digital beam forming based on the statistical channel information and analog beams that the base station uses in actual communication among the analog beams, and a communication unit.
