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). An apparatus includes at least one transceiver, and at least one processor, coupled to the at least one transceiver, configured to determine at least one terminal having a value lower than or equal to a threshold among terminals in a coverage of the base station, the value indicating a signal quality, to identify another value for indicating interference in the coverage, to identify a resource pool allocated for the determined at least one terminal and shared with neighboring base stations around the base station based on determining that the another value exceeds another threshold, and to transmit a message for instructing to modulate a signal to be communicated via the identified resource pool based on a frequency and quadrature-amplitude modulation (FQAM) scheme in the neighboring base stations.
