Original Abstract Submitted
The optical repeater system of an embodiment includes master units connectable to a base station to which a carrier band to be subjected to carrier aggregation is assigned and a remote unit capable of transmitting and receiving an uplink/downlink signal of the carrier band. The master unit includes memory, timing detector, information sharer, determinator and synchronization controller. The memory stores a weight assigned to the each master unit. The timing detector detects a UL/DL switching timing for each carrier band of a subordinate base station. The information sharer communicates with another master unit and shares information including at least the weight and a latest UL/DL switching timing among the detected UL/DL switching timings with the another master unit. The determinator determines the own UL/DL switching timing based on the shared information. The synchronization controller sets the own UL/DL switching timing to the determined UL/DL switching timing.
