Claim:
1. A method of physical cell ID (PCI) classified self-configuration, comprising: accumulating a plurality of PCIs; dividing all PCIs into Δ and then dividing resources of each of the large groups into Δ generating a PCI resource list, allocating all PCIs separated by the step length Δ allocating all PCIs separated by the step length Δ identifying each PCI in the PCI resource list by three sections of address codes, wherein the three sections of address codes represent a large group number, a small group number and an intra-group number of PCI, respectively; mapping the PCI resources one by one to new base stations in accordance with a classification such that each new base station and heterogeneous nodes covered thereby correspond to a small group of PCI resources; forming a base station cluster from Δ allocating a first PCI in each small group of PCI resources to a new base station, and randomly allocating the remaining PCIs in the small group of PCI resources to the heterogeneous nodes which are covered by the new base station.
