Title:
OPTICAL REPEATER SYSTEM, OPTICAL REPEATER DEVICE, MASTER UNIT, AND SYNCHRONIZATION CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2023/171237
Kind Code:
A1
Abstract:
According to an embodiment, each master unit comprises a storage unit that stores a weight previously assigned thereto, a timing detection unit, an information sharing unit, a determination unit, and a synchronization control unit. The timing detection unit detects a UL/DL switching timing in each carrier band of a base station subordinate thereto. The information sharing unit performs communication with another master unit, and shares with the other master unit information including at least the weight and the latest UL/DL switching timing out of the detected UL/DL switching timings. The determination unit self-reliantly determines the UL/DL switching timing thereof on the basis of the shared information. The synchronization control unit sets the UL/DL switching timing thereof to the determined UL/DL switching timing.
