Abstract:
1. A base station, comprising: a reception unit configured to receive, from a plurality of first terminals receiving interference signals from the base station, information of interference channels between the base station and the plurality of first terminals, the plurality of first terminals being located in a neighbor cell adjacent to a target cell of the base station; a virtual cell modeling unit configured to model the plurality of first terminals and a plurality of cooperative base stations into a virtual cell, based on the received information of interference channels between the base station and the plurality of first terminals, wherein the plurality of cooperative base stations are configured to transmit first data signals to each of the plurality of first terminals; and a transmission power determination unit configured to determine a transmission power for each of a plurality of frequency bands with respect to a plurality of second terminals receiving second data signals from the base station, based on the virtual cell such that the transmission power determination unit is configured to control the transmission power of the second data signals according to the received information of interference channels between the base station and the plurality of first terminals, wherein the information comprises at least one of: an identifier of each of the plurality of first terminals, a channel gain of the interference channels, a transmission power of the first data signals, and data transmission priority of the plurality of first terminals, and wherein a reception cycle for the identifier of the first terminal is shorter than a reception cycle for each of: the channel gain of the interference channels, the transmission power of the first data signals, and the data transmission priority of the first terminal.
