| 摘要 |
This invention relates to a method of measuring a characteristic of a radio signal and apparatus therefor, in particular for use in a CDMA cellular communication system. The invention includes means (307) for power down intervals being designated for a plurality of base stations (301, 303, 305). The base stations include means for powering down (323, 325, 327) and means (311, 313, 315) for transmitting a radio signal. In each designated power down time interval some base stations (301, 303, 305) will transmit a signal whereas other base stations (301, 303, 305) will power down. The system also comprises a receiver (309) for measuring a characteristic of the transmitted signal. The time intervals are chosen to be at least partly overlapping thereby allowing a signal from a weak base station to be detected and a characteristic determined when a strong interferer is powering down. The invention is specifically applicable to the Universal Terrestrial Mobile Telephone system (UMTS). |
