Abstract

In a Long Term Evolution (LTE) cellular radio system method of selecting a physical cell id (PCI) of a LTE cell is obtained by reporting PCIs of neighbors and also a parameter indicating each neighboring cell's relevance also termed visibility to the cell. A new cell added in a cellular radio, system can then make an improved selection of a PCI already at the very first neighbor relation establishment; even if all available PCIs are already used in the vicinity.
