  • Patent number: 10499331
    Abstract: 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.

  • Patent number: 9313750
    Abstract: A frequency management method and device as well as a wireless system are provided by which acceptable transmit power is efficiently determined for transmitting stations in a system on the interfering side, neither with concentration of processing load on some part nor with redundant processing. When a frequency management apparatus (50_1) receives a notice regarding a change in the state of frequency use from a radio station (20_1) under its own management (S101), the frequency management apparatus (50_1) sets acceptable transmit power for radio stations (20_1, 20_2) under its own management and radio stations (20_3, 20_4) managed by another frequency management apparatus (50_2), based on the notified change in the state of frequency (S103, S104).
