Patent ID: 8504086

Claim:
A method for allocating a Physical Cell Identifier (PCID) in a wireless communication system, the method comprising: acquiring an allowable PCID list from a server; determining a set of candidate PCIDs from the allowable PCID list according to one or more PCID allocation conditions; measuring a received signal strength of each cell using the determined set of candidate PCIDs; and selecting at least one PCID by using a PCID reuse factor and the received signal strength of each of the cells using the determined set of candidate PCIDs, wherein the PCID reuse factor is determined based on at least one of a cell population density, and propagation characteristics of each of the cells, wherein selecting at least one PCID by using a PCID reuse factor and the received signal strength of each of the cells using the determined set of candidate PCIDs comprises: as the PCID reuse factor increases selecting a PCID with more received signal received power (RSRP) value among the RSRP values for the all the candidate PCIDs.
