A schedule coordinator schedules an air resource of a virtual distributed unit (vDU) in a wireless communication system. The schedule coordinator identifies a radio unit (RU) to be migrated to a target vDU, from among one or more RUs connected to a source vDU, requests the source vDU to exclusively transmit or receive first information including synchronization information of one or more user equipments (UEs) connected to the RU. The schedule coordinator allocates a source vDU-dedicated air resource to the source vDU, and allocates a target vDU-dedicated air resource to the target vDU. When a migration of the RU is completed, the schedule coordinator requests the target vDU to exclusively transmit or receive the first information, and requests the source vDU to stop transmitting or receiving the first information.

Method and apparatus for scheduling air resource of virtual distributed unit in wireless communication system

A method of communication by a radio access network device including a distributed unit (DU) may include obtaining information about resource usage of a first DU executed through a first server by a scaling controller, selecting a second DU based on the information about the resource usage of the first DU by the scaling controller, selecting a second RU to migrate to the second DU from among at least one first remote unit (RU) processing a service of the first DU by the scaling controller, and transmitting information about the second RU to the second DU by the first DU, wherein a remaining RU except for the second RU among the at least one first RU is configured to process the service of the first DU. Other various other embodiments are possible.
