An energy-saving strip coverage relay station deployment method

Abstract

The invention discloses an energy-saving band-shaped coverage relay station deployment method. The method comprises following steps of firstly, analyzing the length and width of a band-shaped closed region; considering to use a divide cover deployment method to cover the band-shaped region completely; further building an interference weight value matrix among relay stations; constructing a basic model which ensures that the interference weight value matrix among the relay stations is a zero matrix, ensures the spectral efficiency and synchronously maximizes the energy efficiency; using an exhaustive search method to search optimum distances among the relay stations; and finally determining the positions and the quantity of the relay stations. The method can be applied in a cellular relay network. According to the method, the relay stations can be directly deployed in the weak band-shaped region; the total energy consumption of the communication system is reduced; moreover, the system spectral efficiency and the user quality of service are ensured; and the method can be extended to deploy other weak regions, such as airport runway and high-speed rail, of the cellular network.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an energy-saving band-coverage relay station deployment method. Background technique [0002] With the development of wireless communication technology and the rapid growth of the number of mobile users, people's requirements for wireless network signal coverage are also increasing, and people expect to be able to exchange information with anyone in a timely manner anytime, anywhere. In the LTE-A system, relay technology is considered to be a key technology, which can improve group mobility, improve cell edge throughput, expand cell coverage area, and be applied to temporary network deployment, etc. At present, the 3GPP has completed the pre-standardization work on the wireless relay, and the Type I relay will be deployed in the LTE-A system as a basic relay type. [0003] The signal attenuates as the distance increases, and the coverage of the base station is als...
