Example Embodiment

[0053] Figure 1 shows the spectrum efficiency of the system at different distances from the base station under different cellular structures. The relay structure here means that a relay station is placed in the middle of the coverage area. The height of the relay station is half the height of the base station, and a multi-antenna configuration is adopted at the relay point. In the figure, it is assumed that the cell radius is 4km, and the spectrum efficiency is compared between the traditional cellular structure and the relay network structure. It can be seen from the figure that after the relay technology is adopted, the spectrum efficiency of the system is significantly improved, especially the use of MIMO at the relay station, which can significantly improve the network performance.

[0054] Figure 2 compares the performance results of relay diversity gain with a single antenna and a 2×2 MIMO antenna. It can be seen from the figure that in the area close to the base station, th...

Abstract

This invention relates to one new wireless communication network form method based on relay technique, which lowers the base station requires through setting relay station and expends its coverage range to reduce near station interference and provides sparse gains to make the next generation of wide band near one and to simplify the next generation of network design to improve system frequency spectrum rate. The technique is characterized by the following: a, relay points adopt antenna; b, in coverage range, relay point fulfills range coverage function; c, in bad area of signal quality the relay point provides one sparse gains function.

Description

technical field [0001] The invention belongs to the field of wireless communication, and is not only suitable for traditional cellular mobile communication systems, but also for various wireless broadband access systems, such as wireless local area networks, wireless metropolitan area networks, etc., and is also suitable for heterogeneous wireless access systems. Access network convergence also has a wide range of applications. The present invention mainly focuses on the elaboration of the downlink information processing, but for the uplink, a similar method can be used. Background technique [0002] The traditional cellular mobile communication system adopts the cellular structure, but the fourth-generation (4G) wireless communication system with ultra-high data rate still adopts the traditional cellular structure, and there will be many problems. The main reasons are: first, the transmission rate of the 4G system is higher than that of Third generation (3G) systems are tw...
