Abstract
A threshold computation apparatus obtains estimated interference power for an uplink from a terminal to a base station; a predetermined communication quality value necessary for the uplink; a maximum value of transmission power of the terminal; and transmission power of the base station for a downlink from the base station to the terminal. The apparatus subtracts a logarithmic value of the maximum value of the transmission power of the terminal from a logarithmic value of the transmission power of the base station for the downlink; adds a logarithmic value of the communication quality value and a logarithmic value of the estimated interference power to a result of the subtraction; and determines a result of the addition to be a logarithmic value of received power at the terminal; and computes a threshold based on the logarithmic value of the received power at the terminal and predetermined conditions.
