Claim 10:
11. The control method of claim 10, further comprising, after the step of providing a radio signal from the base station to the baseband modem via a DU-CU interface through the RF device, the steps of:
transmitting the oscillator clock of the central unit (CU) to each distributed unit (DU);
synchronizing an oscillator clock of the DU by each distributed unit (DU), based on a difference between the oscillator clock of the DU and the oscillator clock of the CU;
providing a synchronized oscillator clock as a reference clock to an RF device of the DU; and
providing a radio signal from the base station to the baseband modem via a DU-CU interface through the RF device.
