摘要

A timing control method, performed by a first DU including a processor and a modem in a base station supporting function-splitting, includes obtaining, by the processor, first time information from a CU included in the base station; obtaining, by the processor, synchronization information with a first system based on the first time information; identifying, by the processor, a change time point of an SFN based on the synchronization information; generating, by the processor, a first timing control signal including a signal indicating a changed SFN and a first tick signal having a same periodicity as a change periodicity of the SFN when the SFN is changed; and providing, by the processor, the first timing control signal to the modem.

說明書

The processor 210 may execute a program stored in at least one of the memory 220 and the storage device 260. The processor 210 may refer to a central processing unit (CPU), a graphics processing unit (GPU), or a dedicated processor on which methods in accordance with embodiments of the present disclosure are performed. Each of the memory 220 and the storage device 260 may be constituted by at least one of a volatile storage medium and a non-volatile storage medium. For example, the memory 220 may comprise at least one of read-only memory (ROM) and random access memory (RAM).
