Abstract: A method of a central unit—control plane (CU-CP) included in a base station in a wireless communication system and an apparatus therefor are provided. The method includes identifying information on a radio link of at least one cell associated with the base station, transmitting, to a central unit—user plane (CU-UP), information indicating downlink transmission stop or resume of the CU-UP included in the base station based on the information on the radio link, and transmitting, to a distributed unit (DU), information indicating downlink transmission stop or resume of the DU based on the information on the radio link. The method relates to converging a 4th-Generation (4G) or a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4G system with a technology for Internet of Things (IoT), and may be applied to intelligent services based on the 5G communication technology and the IoT-related technology.
