Base station, communication method and wireless communication system

摘要

A base station, to which a cell belongs and which communicates with a relay node to which a relay node cell belongs, includes a control unit configured, at a time of handing over the relay node from the cell of the base station to a first cell belonging to a first base station, to extract information indicative of a non-overlapping cell between a first handover destination neighbour cell list containing neighbour cell information of a first neighbour cell adjacent to the first cell at a handover destination and a first handover source neighbour cell list containing neighbour cell information of a neighbour cell adjacent to the cell at a handover source, and to update a neighbour cell list corresponding to the non-overlapping cell by deleting the relay node cell belonging to the relay node from the neighbour cell list based on the information indicative of the non-overlapping cell.
