Optimization method of spectrum efficiency and energy efficiency of wireless communication system

Abstract

The invention discloses an optimization method of spectrum efficiency and energy efficiency of a wireless communication system. The optimization method of the spectrum efficiency and the energy efficiency of the wireless communication system aims at the defects that an existing wireless communication system particularly emphasizes on improvement of the spectrum efficiency and pays less attention to decrease of the corresponding energy efficiency. Firstly, through analysis of intra-cell interference and inter-cell interference of the wireless communication system, spectrum efficiency and energy efficiency expressions about the number and location of relay stations are obtained, a spectrum efficiency and energy efficiency balance primary algorithm model is built, and optimized deployment is carried out according to the relay stations. Secondary, united dormancy dispatch of a base station and the relay station is carried out according to business flow. Finally, optimized spectrum sharing of the base station and the relay station is carried out. The optimization method of the spectrum efficiency and the energy efficiency of the wireless communication system can be applied to a cellular relay network, enables the communication system to reduce energy consumption and improve system throughput through balancing the spectrum efficiency and the energy efficiency of the wireless communication system, and satisfies requirements of energy conservation and emission reduction and requirements of reducing communication operating cost.
