RADIO COMMUNICATION SYSTEM, ITS FREQUENCY HOPPING METHOD, BASE STATION, AND MOBILE STATION

摘要

PROBLEM TO BE SOLVED: To provide a radio communication system for controlling frequency hopping to measure the phase shift amount.

SOLUTION: A control unit 17 of a base station 1 sets a frequency hopping cycle longer than a predetermined value during a certain measurement interval in which the estimation of frequency deviation is conducted, allowing the reception of a plurality of reference signals of the same frequency in receiving an uplink signal from a mobile station 2. The control unit 17 of the base station 1 controls a reference signal extraction unit 15 and a reference signal phase difference calculation unit 16 so as to measure, based on the plurality of reference signals, the phase shift amount of a received signal at the same frequency.
