1. A method performed by a network entity in a wireless communication system using an open-radio access network (O-RAN), the network entity including a near-real-time radio access network (RAN) intelligent controller (near-RT RIC), the method comprising:
receiving, from a service management and orchestration (SMO), policy information related to energy saving;
receiving, from an E2 node, cell load information;
determining, based on the cell load information, one or more cells to be turned off or on for the energy saving; and
transmitting, to the E2 node, information about the one or more cells to be turned off or on for the energy saving, the E2 node corresponding to a RAN with the one or more cells.
