    摘要: A transmitter, a receiver, and a method for measuring a radio channel based on reference signals transmitted through a predetermined number of OFDM symbols by using multiple antennas in an ultra-high frequency band, and controlling a beam width of analog beams formed by transmission multiple antennas based on the measurement result. The transmitter uniquely distributes a predetermined number of analog beams among the analog beams formed by the array antenna in correspondence to each of the predetermined number of OFDM symbols, and repeatedly allocates the predetermined number of analog beams distributed for each of the predetermined number of OFDM symbols by targeting the subcarriers within the corresponding OFDM symbol. The receiver receives a channel measurement instruction message, measures a channel state based on reference signals transmitted through the analog beams allocated for respective subcarriers, and feeds the channel state measurement result back to the transmitter.

    摘要: A method of feeding back channel information by a receiver in a communication system beam forming is provided. The method includes determining an optimum reception beam using intensities of reference signals received through transmission beams of a base station for a first period through a first path for mapping analog beams of an input signal, and determining an optimum transmission beam of the transmission beams using intensities of reference signals received through the optimum reception beam for a second period through a second path for mapping analog beams of the input signal, and transmitting channel information measured by using a reference signal received through the optimum transmission beam and the optical reception beam to a transmitter.
