METHOD FOR MEASURING INTERFERENCE FROM OTHER CELLS IN SUBSCRIBER STATION, AND INTERFERENCE WAVE DETECTION CIRCUIT

摘要

PPROBLEM TO BE SOLVED: To provide a method for measuring interference from other cells in a subscriber station, capable of considering frequency effective utilization and easily measuring interference waves from the other cells in a fixed radio access system using a TDD system, and an interference wave detection circuit. PSOLUTION: In the method for measuring the interference from the other cells in the subscriber station, the subscriber station capable of conducting radio communication with other stations by time division multiple access/time division duplex operation detects the interference from the cells other than the cell to which the present station belongs. The interference waves from the other cells are measured during the time of guard time GT1 included in a delay measurement frame TS13 allocated to measure the propagation delay time between the present station and a base station or at the time for an incoming channel or at the guard time at the back of the radio frame. The timing of the guard time is detected on the basis of reception level peak detection. PCOPYRIGHT: (C)2003,JPO
