Abstract
In a repeater station for use in a repeater station to repeat a sequence of downward time slots and a succession of upward time slots, a detector (40) detects a synchronizing signal included in a particular one of the downward time slots. A timing circuit (41) produces a first timing signal when a first predetermined duration lapses after detection of the synchronizing signal. The first predetermined duration is preferably predictively determined in consideration of a reception time instant of a particular one of the upward time slots that corresponds to the particular downward time slot. Signals included in each upward time slot are memorized in a memory section (60) with reference to the first timing signal. The timing circuit further produces a second timing signal after the first timing signal to transmit the memorized signals to an upward station. The second timing signal is produced in consideration of a deviation with which the upward time slots reach the upward station.
