Method and device for transmitting and receiving signals in communication system

Abstract

A method for operating a first communication node in a communication system includes the steps of: receiving a first command from a second communication node; identifying reference frequency information for determining, on the basis of the received first command, a lens to be applied to a first antenna that is included in the first communication node and includes a plurality of antenna elements; receiving first scheduling information indicating that a first signal is to be transmitted to the first communication node; determining, on the basis of the first scheduling information, a first frequency at which the first signal is transmitted; determining a first lens on the basis of the reference frequency information and the first frequency; and receiving a first signal incident on at least some of the plurality of antenna elements after being refracted from the first antenna through the first lens.
