Biography

My name is Bahram khan, I am from Swat valley which is the beautiful and green valley of Pakistan (at an elevation of 5,918 meters).

I have completed Bachelor and Master studies in Electrical Engineering from Pakistan, that has given me a comprehensive exposure to the fundamental areas of Electrical Engineering. Furthermore, I have worked for one-year as an internee at Information Broadcasting and national heritage Pakistan, which have provided me substantial experience communicating and collaborating with people at all levels and across the discipline within organization, Also Form the beginning of my Engineering studies, I am much interested in digitalization and in modern technologies, that’s why I did my thesis based on 5G, which approaches to the digitalization.

In regarding to my extracurricular activities, During my graduation time I was the President of welfare organization, it was the phenomenal time of my life, because I have struggled too much for giving shape to my own Ideas by campaigning among the students and developed welfare organization, moreover I like playing badminton regularly with passion as well as I am much interested in hiking and discovering new places as I have experience of Falak Sair mountain, which is the highest mountain peak in Ushu Valley of Swat Pakistan.

Currently I am the part of TeamUp5G project as PhD student early stage researcher, which focuses on 5th generation technology, specified as Licensed Shared Access in Heterogeneous Network with Small Cells.

Objectives

To explore the Carrier Aggregation technique to obtain high spectral efficiency, through the “massification” of SCs, together with new network technologies like C-RAN. Scenarios with exclusive spectrum access and spectrum sharing will be explored. Spectrum sharing assumes that two or more mobile operators/carriers have dedicated spectrum for macro cellular layer while SCs will use exclusive shared spectrum (by paying a fee) or share the access to non-licensed spectrum in an opportunist manner. Both terrestrial cellular scenarios and HetNets with drone-small cells will be investigated. Prototyping and some tests will be done with programmable electronic envisaging demonstrating the concept in real environments. Cost/revenue optimization of the HetNet considering both macro and SCs is one of the final goals of the research.

Expected Results

Optimization of Carrier Aggregation in LTE-A HetNets with SCs; Implications of RRH and Small Cells in Spectrum Sharing; Optimization of SCell deployment and frequency Assignment (simulation, optimization tool and hardware demonstration with USRPs and OpenAirInterface); Optimization of the Cost/Revenue Trade-off of HetNets with SCs.
