Abstract
This paper presents an efficient solution to physical cell identity assignment problem in 3GPP Long Term Evolution (LTE). The technique takes advantage from the concept of graph coloring and is quite efficient in the sense that minimum number of colors/PCIs is utilized in achieving a collision and confusion free Physical Cell Identity allocation throughout the network. The method has been thoroughly explained using an example, and it has been shown how the technique works and accomplishes the required results. This method is also very much helpful in situations in which somehow a conflict of PCIs occurs between two or more cells. Simulations are performed on a large scale network during initial network wise configuration stage, in which all the cells are without any PCIs assigned.
