Aplicação e estudo de técnicas de escalonamento e coordenação de interferência em redes lte-a heterogêneas

Abstract

Over the years, the increase in the number of users became quite expressive, and one fact was the one that stood out more and more potentialized. In addition, advanced technologies and techniques used in mobile networks, allows a significant increase in speed, enabling quality services for a large number of users. Nowadays, mobile communications are a factor that deserve more attention, such as intercellular interferences, especially in Heterogeneous networks, and also a matter of scheduling algorithms, which in fact contribute a lot to a greater efficiency of the network, consequently results in a Higher quality of service to the user. For the study of the influence and use of two factors, we used modeling and simulation. In this sense, the two interference communication schemes are tested and propagated by eICIC and FeICIC, (better coordination of inter-cell interference and more eICIC respectively). In addition, the scheduling algorithms are evaluated: the RR (Round Robin), the FP (Proportional Fair) and the GPF (Generalized Proportional Fair). Finally, the results of the simulations performed allowed a visualization of the tests provided by the most elaborated techniques tested, to know, FeICIC and GPF.
