Apparatus and method for slice control and cell control in wireless communication system

The present disclosure relates to a 5th-Generation (5G) or pre-5G communication system for supporting a data rate higher than that of a 4th-Generation (4G) communication system such as Long Term Evolution (LTE). According to various embodiments of the present disclosure, a method performed by a distributed unit (DU) may include: transmitting resource policy information related to a shared resource, a priority resource, and a dedicated resource of radio resources for an rRMPlicyMemberList to a near real-time (near RT) radio access network (RAN) intelligent controller (RIC); and receiving, from the near RT RIC, an E2 control message generated based on the resource policy information; wherein the resource policy information may include an rRM < P > O < x > Ratio, an rRM < P > O < y > MinRatio, and an rRM < P > O < y > Dedicated Ratio, and each of the rRM < P > O < y > MaxRatio, the rRM < P > O < y > MinRatio, and the rRM < P > O < y > Dedicated Ratio may be indicated as an integer between 0 and 100, and at least
