摘要： Because it is not possible to sufficiently reduce the number base stations that start uselessly in spite of being in a low traffic state, it is not possible to lower interference between adjacent cells and power consumption sufficiently. A base station starts transmission of a control signal with predetermined power when communication between another base station and a mobile station is started and a first predetermined condition is satisfied.

摘要： A spectrum manager manages a secondary system that shares a frequency with a primary system. A communication unit receives a measurement value of reception power of a signal of the secondary system which is measured by a monitoring station, and holds the measurement value in a measurement result storage unit. A path loss estimating unit estimates a path loss at a first frequency, and a path loss correcting unit performs actual measurement correction on a path loss estimation value using one of a reception power measurement value of a radio signal of a secondary transmitting station measured at a second frequency different from the first frequency and a reception power measurement value of the radio signal of the secondary transmitting station measured in a period of time which is not used by the primary system. A permissible transmission power setting unit calculates permissible transmission power of the secondary transmitting station using the path loss estimation value which has been actually measured and corrected.
