Investigation of Intercell Interference for Cell Edge Users

Intercell interference (ICI) is considered a critical challenge from earlier mobile generations and it is getting more attention with the arrival of 5G. Its promises of higher data rates, spectral efficiency, and better system capacity that are faced by the shortage of spectrum resources, which require updating the network by dense cells and reusing the frequencies to accomplish these promises. which leads to arising of cell-edge user problems. This paper introduces the concept of ICI in two scenarios. Throughput, good-put, and block error rate (BLER) are used as metrics for the analysis and evaluation of the network’s performance. This paper focuses on cell edge users. The results show these victim users have a throughput of 1.73 and 2.24 Mbps when ICI cells become closer to the cell of interest, while showing improvement in the throughput to reach about 3.14 and 3.45 as the distance from the ICI increases.
