The present disclosure relates to 5th generation (5G) or pre-5G communication system for supporting a higher data transmission rate beyond a 4th generation (4G) communication system such as long term evolution (LTE). An operation method of a base station in a wireless communication system comprises the steps of: reallocating a resource, which has been allocated to a first service, to a second service in order to provide the second service; transmitting control information related to at least one reference signal punctured for reallocation of the resource; and transmitting the at least one punctured reference signal via a resource different from the resource having been allocated to the second service.
