1. An operation method of a terminal in a communication system, the operating method comprising:
obtaining a plurality of serving beam measurement values by performing measurement on a plurality of serving beams received from a plurality of serving transmission and reception points (TRPs) providing a service to the terminal;
identifying a minimum measurement value among the plurality of serving beam measurement values;
obtaining a plurality of beam measurement values by performing measurement on a plurality of beams received from a plurality of TRPs included in the communication system;
determining whether a first condition is satisfied, the first condition being defined based on a result of comparison between the plurality of beam measurement values and a sum of the minimum measurement value and a first offset; and
in response to determining that the first condition satisfied, performing communication with at least part of the plurality of serving TRPs and a first TRP forming a first beam satisfying the first condition.
