Coordinated Multi-Point (CoMP) In Improving Energy Efficiency In LTE-Advanced Cellular Networks

The evolution of mobile communication from its initial state to present i.e. from firstgeneration (1G) to fourth generation (LTE/LTE-Advanced) have been particularlycharacterized with design issues basing on improving data rates, spectral efficiency as wellas throughput.Again in ICT, Mobile Communication base stations have found to be themajor power consumer as well as radiator leading to C02emissions and other associatedcarbon footprint which are indeed harmful to the environment. Different approaches tomitigate the problem of energy efficiency in second generation and Third generation (2Gand3G) have been considered by the way through base station deployment strategies inother words using Optimization techniques design as a way to mitigate this problem.LTE and LTE-Advanced came up with advanced key technological features such asNetwork Relaying, Heterogeneous Networks, Advanced MIMO, Enhanced inter-cellinterference coordination (eICIC) as well as Coordinated Multipoint(CoMP). It is fromthis juncture that this thesis aims at investigating the effects of CoMP deployment and weanalyze contribution in terms of the Energy Efficiency (EE).A power consumption modelis modeled in this thesis and is verified with the help of Energy Consumption Rating (ECR)metric and Bit per Joule spectral energy efficiency metric.Simulation results have clearlyindicated that, with deployment of Base station coordination (CoMP), energy can be savedup to13%simulated along with modeled power consumption model. It is howeveranalyzed that this scheme is not applicable at higher Inter-site distances.
