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.
