PURPOSE:To detect an optimal idle channel by measuring a few channels without increasing the control amounts in a base station, in the method of measuring an interference wave level in a mobile communication system, and detecting an idle channel. CONSTITUTION:The several kinds of sequence tables of the channel for measuring the interference wave level are prepared, and the same sequence table is assigned to each base station 21-23 provided at the interval of a certain distance. The interference wave level is measured by the base stations 21-23, or mobile stations 24-26 according to the assigned sequence table. When the interference wave level is measured by the mobile stations, the sequence table is communicated from the base stations to the mobile stations, and the idle channel detected for the first time by the base stations or the mobile stations according to the sequence table is used for a communication. |
