APPARATUS AND METHOD FOR ADJUSTING A REFERENCE TIMING

摘要

In a communication system including first and second base stations, an apparatus operates as the first base station. The apparatus determines a first reference timing that is used as a reference timing for transmitting a downlink signal, and adjusts the determined first reference timing to a second reference timing being used in the second base station. The apparatus corrects a deviation of the first reference timing from the second reference timing, which has occurred after adjustment of the first reference timing, in accordance with a receiving timing of a preamble signal transmitted from a mobile station device to the second base station.

1. An apparatus in a communication system including first and second base stations, the apparatus operating as the first base station, the apparatus comprising:
a timer; a timing determination unit configured to determine a first reference timing that is used as a reference timing for transmitting a downlink signal, based on a timing measured by the timer; a timing adjustment unit configured to adjust the first reference timing determined by the timing determination unit, to a second reference timing being used in the second base station; and a timing correction unit configured to correct a deviation of the first reference timing from the second reference timing, which has occurred after adjustment of the first reference timing by the timing adjustment unit, in accordance with a receiving timing of a preamble signal transmitted from a mobile station device to the second base station.
