A Novel Radio Resource Management (RRM) Technique for Interference Management in LTE-A HetNet




The heterogeneous network (HetNets) emerges as one of the most auspicious developments toward realizing the target specifications of Long Term Evolution Advanced (LTE-A) and future generations wireless networks. In HetNet, small-cells such as Microcell, Picocell, and Femtocell, etc. are deployed over the Macrocell region and the network traffic is shared by these cells according to some optimization criteria and policy, etc. However, Co-Channel Interference (CCI) and Spectral efficiency are critical challenges that severely affect the system performance in LTE-A HetNet. Therefore, proper Radio Resource Management (RRM) is crucial to mitigate the CCI and obtain higher spectral efficiency. In our research work, we implemented a new Fractional Frequency Reuse (FFR) method in such a way to minimize the CCI and achieve better overall throughput of the system in LTE-A HetNet. In FFR, the entire cell region is split into several zones, and similarly, the total available bandwidth is divided into few fractions (subbands). Subsequently, the subbands are assigned to Macro-Users in different zones and reassigned to Femto-Users in other zones of the cell region.

Biography: Sajjad Ahmad Khan was born on April 11, 1984 in Bannu, Pakistan. After initial education, he moved to the provincial capital city of Peshawar. In 2007, he completed his BS in Information Technology from the University of Engineering and Technology, Peshawar, Pakistan. During the final year of undergraduate studies, he received an indigenous scholarship from the Higher Education Commission of Pakistan to continue post-graduate education. In 2010, he completed his MS in Telecommunication and Networking from IQRA University, Islamabad, Pakistan. Besides higher education, he also worked as Lecturer (Computer Science) in two different institutes of Pakistan. In October 2013, he moved to Turkey to pursue his PhD in Computer Engineering at Kocaeli University, Turkey under the supervision of Prof. Dr. Adnan Kavak. He successfully defended his PhD dissertation on November 28, 2019. Towards PhD studies, he worked as a scientific researcher in different projects such as TUBITAK and BAP, etc. and received several successive scholarships. He published three SCI articles along with some other journal articles and IEEE conference papers, some of his articles are under review. His research area includes Wireless Communications and Networking, Radio Resource Management and Cooperative Communications in LTE-A HetNet, OFDM and beyond Modulation Schemes, MIMO, mmWave, IoT, and Machine Learning, etc.
