Abstract
A frequency allocation part (a frequency allocation device) of a base station device includes a cell-edge area unallocated channel estimation part for estimating a cell-edge area unallocated channel (or a cell-edge area unallocated RB) corresponding to a frequency channel (RB) which an adjacent base station device does not allocate to a mobile station (UE) in a cell-edge area; and a channel allocation part for allocating the cell-edge area unallocated channel, estimated by the cell-edge area unallocated channel estimation part, to a mobile station in a cell area.
Claims8
A frequency allocation device for allocating a frequency channel, used for communication, to a mobile station located in a first cell area of a first cell, comprising:
- a cell-edge area unallocated channel estimation part which estimates a cell-edge area unallocated channel corresponding to a frequency channel different from another frequency channel, which an adjacent frequency allocation device installed in a second cell adjacent to the first cell allocates to a mobile station located in a second cell-edge area of the second cell;
- and
- a channel allocation part which allocates the cell-edge area unallocated channel to the mobile station located in the first cell area.
A frequency allocation device for changing a frequency channel allocated to a mobile station standing still in a cell area of a first cell with respect to time, said frequency allocation device allocating a frequency channel, estimated to be different from a frequency channel which another frequency allocation device installed in a second cell adjacent to the first cell allocates to a mobile station located in a cell-edge area of the second cell, to a mobile station located in a cell-edge area of the first cell prior to a mobile station located in a cell-central area of the first cell.
A program causing a computer of a frequency allocation device for allocating a frequency channel, used for communication, to a mobile station located in a first cell area of a first cell, to implement:
- a cell-edge area unallocated channel estimation step for estimating a cell-edge area unallocated channel corresponding to a frequency channel different from a frequency channel which an adjacent frequency allocation device installed in a second cell adjacent to the first cell allocates to a mobile station located in a second cell-edge area of the second cell;
- and
- a channel allocation step for allocating the cell-edge area unallocated channel to the mobile station located in the first cell area.
