PROJECT TITLE :

Coordinated Framework for Spectrum Allocation and User Association in 5G HetNets with mmWave

ABSTRACT:

Dense deployment of small cells that can operate on multiple frequency bands and are based on multiple technologies provides a fundamental way to deal with the imminent thousand-fold increase in traffic. The architecture of this heterogeneous network, also known as HetNet, makes it possible to offload traffic effectively across a variety of tiers and technologies. In contrast, research on multi-tier HetNets, in which different tiers share the same microwave spectrum, has been given a lot of attention over the course of the past few years. As a result, the focus of our research is on developing novel multi-tier HetNets with diverse spectrums (microwave and millimeter wave). In point of fact, despite the enormous capacity brought about by millimeter-wave technology, the latter will fail to provide universal coverage, particularly indoors; consequently, mmWave will inexorably co-exist with a traditional cellular network operating at frequencies lower than 6 GHz. We use non-cooperative game theory in this work to propose a coordinated user association and spectrum allocation. The goal is to maximize efficiency. In such a challenging environment, it is absolutely necessary to find effective solutions that are distributed across multiple nodes. The results of extensive simulations demonstrate that our coordinated approach is superior to the heuristics that are currently considered to be state of the art. In addition, we evaluate the impact of a variety of network parameters, such as mmWave density, cell load, as well as user distribution and density, in order to offer helpful guidelines into the design of a practical 5G HetNet. In the end, we evaluate the benefits that massive MIMO can bring to mmWave Communications in an environment with such a high degree of diversity.
