1. A cell identifier allocation method for allocating a cell identifier to a target cell of a target base station among a plurality of base stations, the cell identifier allocation method comprising:
measuring a reception power or a propagation loss of a signal received inside the target cell from each of cells of adjacent base stations in a neighborhood of the target cell; identifying a first cell that has a greatest reception power or a lowest propagation loss, from among the cells of the adjacent base stations; and allocating a cell identifier in which a code sequence number of a synchronization signal is different from that of the first cell and that has not been allocated to any of the cells of the adjacent base stations, to the target cell, wherein each of the plurality of base stations forms a plurality of cells, wherein the identifying of the first cell includes:
when plural cells of the target base station are handled as target cells, identifying the first cell for each of the target cells, and wherein the allocating of the cell identifier includes:
when plural cells of the target base station are handled as the target cells, giving priority to the each of target cells, in a descending order of the reception power of the first cell, or in an ascending order of the propagation loss of the first cell;for each of the target cells, in an order of the highest priority, identifying a second cell that has the lowest reception power or the greatest propagation loss, from among the cells in which the code sequence number of the synchronization signal is different from that of the other target cells, and which are formed by one of the adjacent base stations that forms the first cell; andfor each of the target cells, in an order of the highest priority, allocating a cell identifier in which the code sequence number of the synchronization signal is the same as that of the second cell and that has not been allocated to any of the cells of the adjacent base stations, to each of the target cells. |
