LTE-Advanced – Interference Management in OFDMA Based Cellular Network: An Overview

Abstract

From 1G in late 80s to 5G in 2019, revolutionary changes have been emerged in the telecom sector. Higher data rate, spectral efficiency and performance are the focusing areas. Radio spectrum is vital to cellular network and one of the most expensive and scared resource. It needs to be utilized efficiently and requires high level of manageability. An effective Frequency Reuse or Frequency Planning scheme ensures an efficient utilization of radio spectrum provides higher data rate increases coverage area expands network capacity and thus overall performance. Any increase by applying Frequency Reuse scheme may also lead to interference which significantly decreases the network performance. The paper overviews the requirements, standards and different kinds of interference and their management in LTE-Advance cellular network which more or less are the fundamental of 5G technology.
