Device and method for transmitting and receiving control information in wireless communication system

Abstract

The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A base station operation method in a wireless communication system, according to an embodiment of the present invention, comprises the steps of: determining, on the basis of channel information received from each of a plurality of terminals, power to be used by each of the plurality of terminals with respect to resources allocated to be overlaid and used by the plurality of terminals; and transmitting resource information, which comprises information about the determined power, to each of the plurality of terminals.
