Abstract

To prevent interference by a mobile station conducting communication with high electric power, it is judged whether a radio base station which is the source of interference is in a macrocell or microcell. The base station adds the value of transmission power of the downstream report channel to report information. A newly established base station (C) receives a downstream frequency band, measures the reception level of the report channel, and acquires the value of transmission power. If the value of transmission power is large, the threshold value is lowered (THRb); and if the value of transmission power is small, the threshold value is raised (THRa). If the reception level (L) is below the threshold value, the channel is judged to be usable. From the reception level of the report channel and the acquired value of transmission power, the propagation loss is calculated, and if the propagation loss is below a value and the reception level is below the threshold value, the channel is judged to be usable.
