  • Publication number: 20130242791
    Abstract: The present invention relates to a method and apparatus for controlling transmission power of the base station in a wireless communication system and includes calculating signal-to-noise ratio of a target component carrier and recovering the signal-to-noise ratio to be equal to or greater than a threshold by increasing a transmission power to a predetermined level and requesting, when the signal-to-noise ratio is less than a predetermined threshold, a neighbor base station to decrease the transmission power. According to the present invention, it is possible to suppress the inter-cell interference and improve channel utilization efficiency, resulting in improvement of the throughput of the wireless communication system.

  • Publication number: 20130242935
    Abstract: The present invention relates to a method and a device for managing resources of a base station in a wireless communication system. The method comprises: calculating an average resource use of serving resources, which are used as downlinks from a serving base station to a plurality of communication terminals; selecting one of the communication terminals, which has a maximum interference from a neighbor base station, if the calculated average resource use exceeds a preset threshold; and making a reservation for at least one of neighbor resources used as downlinks from the neighbor base station, the at least one neighbor resource corresponding to the serving resource for the selected communication terminal, so that the neighbor base station may decrease transmission power in the at least one neighbor resource.
