Abstract: A method of operating a communication device includes: sweeping a plurality of first reception beams; measuring reference signals, received from another communication device, based on the plurality of first reception beams; estimating a downlink channel gain based on the measured reference signals and reception array response information corresponding to reception antenna characteristics of the communication device; generating a downlink channel related matrix based on the downlink channel gain and the reception array response information; determining a second reception beam based on the downlink channel related matrix; determining a transmission beam based on at least one of the downlink channel gain, the downlink channel related matrix, and the second reception beam; and performing communication with the other communication device using the second reception beam and the transmission beam.

Abstract: A wireless communication method is provided in which beam training phases alternate with data transmission phases. The method includes estimating a first channel based on a signal received using one or more first training beams in a first beam training phase, and calculating, based on the estimated first channel and a first objective function corresponding to the estimated first channel, a first data beam for a first data transmission phase from the one or more first training beams in the first beam training phase, the first data transmission phase following the first beam training phase.
