WIRELESS BASE STATION DEVICE, AND TRANSMISSION POWER DETERMINATION METHOD

摘要

A wireless base station device comprising a function for determining transmission power, said wireless base station device comprising: a peripheral cell detection unit that detects peripheral cells which interfere with a target cell that can be formed by the wireless base station device; a reception power measurement unit which, for each peripheral cell detected by the peripheral cell detection unit, measures the reception power from said peripheral cell; and a transmission power determination unit which, for each bandwidth section within the transmission bandwidths of the peripheral cells that overlaps the transmission bandwidth of the wireless base station device, calculates the sum of the reception powers of the peripheral cells that have a transmission bandwidth including said bandwidth section, determines the amount of interference in the target cell on the basis of the sum of the reception powers, and uses the interference amount to determine the transmission power.
