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

Meanwhile, each of the plurality of base stations 110-1, 110-2, 110-3, 120-1, and 120-2 may operate in the same frequency band or in different frequency bands. The plurality of base stations 110-1, 110-2, 110-3, 120-1, and 120-2 may be connected to each other via an ideal backhaul or a non-ideal backhaul, and exchange information with each other via the ideal or non-ideal backhaul. Also, each of the plurality of base stations 110-1, 110-2, 110-3, 120-1, and 120-2 may be connected to the core network through the ideal or non-ideal backhaul. Each of the plurality of base stations 110-1, 110-2, 110-3, 120-1, and 120-2 may transmit a signal received from the core network to the corresponding terminal 130-1, 130-2, 130-3, 130-4, 130-5, or 130-6, and transmit a signal received from the corresponding terminal 130-1, 130-2, 130-3, 130-4, 130-5, or 130-6 to the core network.
