Capacity Aware Resource Allocation in Millimeter Wave Micro Urban Communication Network

摘要

In this changing world, with the advent of technology, users are increasing massively, so are the demands. To cater such demands, there is a need of extensively high bandwidth. Moreover, the current technology of LTE is making is difficult for users to explore the modern technologies like Big Data, IoT fully. Thus, there is a need to move from LTE to 5G. The upcoming 5G emphasizes mainly on providing the following Six requirements i.e, higher capacity, extensively higher data rates, lower End-to-End latency, enormous device-to-device connectivity, less cost and consistent resourcing of Quality of Experience. To address that, 5G implements millimeter Wave which is unused and unlicensed spectrum between 30–300 GHz. In addition to this, the resources are allocated to the system in such a way that each cell is able to use the resources uniformly. In this paper, a hybrid heterogeneous system model is constructed, which has the potential to be working in multi-tier system. In such multi-tier system, one tier is proposed which is comprising of geographic region lying in the Macro base station range which communicates with the small cell base stations using RF communication and the other tier consisting of the region which uses millimeter Wave to communicate within the base stations and UE. A new optimal resource allocation algorithm has been proposed for our multi-tier heterogeneous network which will work upon and analyze the scenario of micro urban and accordingly find out the best possible cell arrangement.
