Title:
METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING SIGNAL IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/107327
Kind Code:
A1
Abstract:
A method and apparatus for transceiving a signal in a wireless communication system is provided. A base station for transceiving a signal in a wireless communication system includes a transceiver and at least one processor. The transceiver includes an antenna unit and a metamaterial unit. The metamaterial unit includes a metamaterial lens unit and a metamaterial lens controller, and the at least one processor is configured to generate a first beam via hybrid beamforming in the antenna unit; transmit the generated first beam to the metamaterial lens unit, generate a second beam from the first beam, by adjusting the metamaterial lens unit, based on a control signal generated by the metamaterial lens controller, and transmit a downlink signal to a terminal by using the generated second beam.
