Document Type and Number:
WIPO Patent Application WO/2009/003312
Kind Code:
A1
Abstract:
A method for controlling the signal relay in a relay station in wireless relay network and a device thereof are provided in the invention, the relay station first detects the signal quality of the signal from an anterior device, and generates the signal quality relate information (S11); then, on the basis of the signal quality relate information, selects a corresponding relay work mode to relay the signal from the anterior device (S12). The method of the present invention combines the advantage of the two relay work modes in the prior art, and has preferable adaptability in different application scenes. The technique scheme can be combined with Hybrid Auto Retransmission Request (HARQ) and cooperation relay technique easily, and can realize the time and space diversity gain totally.
