ENERGY PERFORMANCE OPTIMIZATION OF 5G NETWORK USING CELL DISCONTINUOUS TX

Abstract

ABSTRACT Due to the huge increase and continuous demands for wireless access networks, the energy consumption will increase more and more. This situation impels big challenges for mobile operators due to the cost of energy and increases worrying about sustainable development and global warning. This thesis focuses on the energy efficiency issues in the new access wireless system at 5G, and how to reduce the energy consumption. The study and focusing on the energy performance of the system in specific manner to reduce the power consumption for various BS types including: (macro, micro, pico, and femto BSs).then the BSs load dependency with different BS types was studied, Finally the daily average area power consumption of 5G system was presented and the results are compared with traditional LTE system at the same network design with using Cell-DTX in various BS types (macro, micro, pico, and femto BSs). Cell-DTX is a new feature that operates during the transmission time intervals (TTIs) when there is no traffic, which enables the BSs to deactivate some components and sleep mode operations at BS. we conclude that the power consumption for macro BSs is load dependent, and less dependent for micro BSs, while it's almost negligible for pico and femto BSs. Comparing the daily average area power consumption for different traffic demands shows that 5G system saves for about 51% to 69% at low and medium area traffic demands respectively in all type of BSs.
