Abstract
Geographical coordinates for a cell are obtained based upon the location of the cell, generating a physical layer cell identity matrix for the cell based upon a subset of physical layer cell values allocated for the location of the cell which is performed to eliminate interference among primary and secondary synchronization signaling for the cell based upon a subset of physical layer cell values allocated for the location of the cell, using one of the cell identities contained in the generated matrix for the new cell which is mapped to the location of the new cell and monitoring for physical layer cell color code collisions among neighboring cells reported by one or more user equipment in range of the new cell and neighboring cells, and if a collision occurs re-generate a physical layer cell matrix using unallocated physical layer cell values for the location of the new cell.
