Abstract

Provided are a base station device and a transmission power control method that reduce interference with an uplink radio channel from a femto-connected terminal to a macrocell base station while avoiding an increase in signaling. A measurement unit () measures the macrocell signal reception level, and a propagation loss estimating unit () estimates propagation loss between a HUE and a HNB based on the HUE signal reception power, for example. A judgment unit () performs a first comparison of the macrocell signal reception level with a first threshold value and a second comparison of the propagation loss with a second threshold value, and an adjustment unit () generates a command to reduce the maximum value that is possible for the target control value for the HNB total reception power when the macrocell signal reception level is at least the first threshold value and the propagation loss is at least the second threshold value. A scheduler () determined a transmission rate allocated to the HUE based on the HUE signal and the maximum value that is possible for the target control value for the HNB total reception power.
