Drahtloses Kommunikationssystem und Frequenzsprungverfahren dafür, sowie Basisstation und Mobilstation |
摘要 |
<p>In a wireless communication system, 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 an measurement of a frequency drift is conducted, allowing 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) 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. Thus, the wireless communication system can measure the phase shift amount by controlling the frequency hopping.</p> |
