Abstract
Provided is a compact base station apparatus (HeNB) whereby frame timing can precisely be synchronized between HeNB and MeNB, thereby suppressing the interference in an upstream channel. In HeNB (), which forms a cell smaller than a cell formed by MeNB, frame timing detecting unit () detects, based on a sync signal received from MeNB, the frame timing of MeNB; a control unit () uses the frame timing of MeNB to set the frame timing of a downstream channel in HeNB (); a transmission RF unit () transmits, in accordance with the frame timing of the downstream channel in HeNB (), a preamble to MeNB; and a TA command extracting unit () acquires, from a response signal responsive to the preamble, information indicating a difference in frame timing between MeNB and HeNB ().
