A method for mitigating interference at a small base station in a hierarchical cell structure is provided. In the method, the small base station checks a sub-frame allocated to macro user equipment by using a downlink signal received from a macro base station when an interference candidate user equipment list is received. The interference candidate user equipment list contains information on the macro user equipment adjacent to a femto cell controlled by the small base station. Then the small base station allocates other sub-frame to femto user equipment located in the femto cell by avoiding the sub-frame allocated to the macro user equipment.

In a radio access network (14) comprising a serving radio network control node (26₁) and a drift radio network control node (26₂), a determination is first made that a target cell controlled by the drift radio network control node should be prepared for handover with respect to a user equipment unit (30). The target cell is neighbored by a set of neighboring cells, the set of neighboring cells including a first subset of neighboring cells and a second subset of neighboring cells, a handover involving the user equipment unit being permitted for a cell of the first subset but not for a cell of the second subset. In accordance with the determination, a message including a filtered list of cells is sent to the user equipment unit, the filtered list of cells including the first subset but not the second subset. The filtered list of cells can comprise, for example, a list of cells for whose frequencies the user equipment unit is to perform measurements. Which nodes perform the actions of (1) determining an allowed area(s) for the user equipment unit; and (2) preparing the filtered list of cells using the allowed area(s) depends on which of various alternative implementations are utilized.

A method and apparatus for resource allocation in a multi-carrier wireless communication system enables transmission using smaller resource units and achieves efficient transmission of data channels with very low data rates, scheduling a greater number of user equipments without additional control channel overhead while maintaining compatibility with the resource allocation scheme of legacy user equipments. Thus, one cell controls a larger number of user equipments. In addition, as multiple user equipments are scheduled using a single control channel, resource efficiency is increased.
