Communication repeater system and method

According to one embodiment, a communication repeater system repeats communication by time division duplex scheme. The system includes a timing detector that detects each of transmission/reception switching timings between a master station device and each of radio frequency units, a protection level detector that detects a level of synchronization protection of each of base station systems, a setter that sets, as reference transmission/reception switching timing, a transmission/reception switching timing corresponding to one of the base station systems having a higher level of synchronization protection among the transmission/reception switching timings on the basis of a result of the detection by the protection level detector, and a corrector that corrects a variation in the transmission/reception switching timings in accordance with the reference transmission/reception switching timing.
