Disclosed are methods for transmitting and receiving beamforming-based signals in a communication system. An operation method of a terminal may comprise transmitting capability information of the terminal to an AN; receiving first configuration information of a network cluster configured based on the capability information from the AN; transmitting an SRS in a beamforming scheme through resources indicated by the first configuration information; receiving second configuration information of a user cluster configured based on a measurement result of the SRS from the AN; and performing cooperative communication with ANs belonging to the user cluster, which are indicated by the second configuration information. Accordingly, the performance of the communication system can be improved.
