FIELD: radio engineering, communication.
SUBSTANCE: techniques for a precoding scheme for wireless communication are described. The method and apparatus may include a first device for a communication system to determine a beamforming structure for a closed loop transmit beamforming scheme using channel information, one or more scaling factors and one or more integers to represent a complex vector. The beamforming structure may include a codeword, a codebook and a codeword index.
EFFECT: improved beamforming.
