An apparatus of a base station in a wireless communication system supporting time division duplex (TDD) and a method thereof are provided. The apparatus includes at least one transceiver, and at least one processor operatively connected with the at least one transceiver. The at least one processor may be configured to perform signaling for preventing transmission of an uplink (UL) signal in a cell, and measure a strength of a downlink (DL) signal received from at least one base station during at least one symbol in a UL subframe. The apparatus 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).
