Zusammenfassung:According to various embodiments of the present disclosure, an operation method of a management device in a wireless communication system comprises the processes of: acquiring measurement results for each of a plurality of cells; based on the measurement results, identifying an aggressor cell and a victim cell due to atmospheric interference among the plurality of cells; and performing interference control for at least one of the aggressor cell and the victim cell. The measurement result may include interference information related to a downlink signal of at least one other cell measured in an uplink resource period of a measurement cell and cell information of the at least one other cell. Accordingly, by checking the interference relationship based on the measurement results, interference between base stations can be effectively controlled. 본 개시의 다양한 실시 예들에 따르면, 무선 통신 시스템에서 관리 장치의 동작 방법은 복수의 셀들 각각에 대한 측정 결과를 획득하는 과정과, 상기 측정 결과에 기반하여, 상기 복수의 셀들 중에서 대기 간섭에 의한 공격자 셀(aggressor cell)과 희생자 셀(victim cell)을 식별하는 과정과, 상기 공격자 셀 및 희생자 셀 중에서 적어도 하나에 대한 간섭 제어를 수행하는 과정을 포함하고, 상기 측정 결과는, 측정 셀의 상향링크 자원 구간에서 측정되는 적어도 하나의 다른 셀의 하향링크 신호와 관련된 간섭 정보 및 상기 적어도 하나의 다른 셀에 대한 셀 정보를 포함할 수 있다.
