Physical cell identity allocation
The invention discloses Physical Cell Identity (PCI) allocation in a cellular network. Radii of an inner boundary circle of a first and second cell are each estimated according to a cell distance relation model. Signal strengths within the inner boundary circles of the first and second cells are each greater than a first threshold. Then radii of an outer boundary circle of the first and second cell are each estimated according to the cell distance relation model. The signal strengths within the outer boundary circles of the first and second cells are each greater than a second threshold, where the second threshold is lower than the first threshold. The second cell is allocated a PCI based on a distance relation between the first cell and the second cell.
