  • Patent number: 11855730
    Abstract: The disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data rate after a 4th generation (4G) communication systems such as long term evolution (LTE). The disclosure is for reconstructing a downlink channel in a wireless communication system. An operation method for a base station is provided. The operation method includes the steps of transmitting downlink reference signals (RSs) to a terminal, receiving an indication of a first channel matrix estimated by the terminal and at least one uplink RS; estimating a second channel matrix on the basis of the at least one uplink RS, and on the basis of the first channel matrix and the second channel matrix, reconstructing channel information to be used for data transmission.

  • Publication number: 20230336224
    Abstract: A method performed by a base station in a wireless communication system, includes: determining, from among a plurality of antennas of the base station, a first antenna that meets a power threshold, based on a first beamformer scaled according to a power limit; generating a second beamformer corresponding to the first antenna; applying an overlap coefficient matrix to the second beamformer; generating a third beamformer by combining the second beamformer to which the overlap coefficient matrix has been applied and the first beamformer; and transmitting a signal using the third beamformer.

  • Patent number: 10958330
    Abstract: A communication system is provided. The communication system supports higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A first apparatus in a wireless communication system is provided. The apparatus includes an antenna array, at least one transceiver, and at least one processor. The transceiver is configured to transmit signals by using a beam set, and receive a signal for indicating at least one beam in the beam set from a second apparatus. The processor is configured to determine an auxiliary beam pair, based on the at least one beam. The transceiver is configured to transmit reference signals to the second apparatus by using the auxiliary beam pair, and receive feedback information relating to the auxiliary beam pair from the second apparatus. The at least one processor is configured to determine, based on the feedback information, a communication direction relating to the second apparatus.
