Abstract

The invention relates to a method for realizing the coexistence of the transparent transmission and the non-transparent transmission of relay nodes. The method is realized in a frequency division multiplexing way by adopting a transparent transmission mode on one working carrier frequency while adopting a non-transparent transmission mode on the other carrier frequency. The method is realized in a time division multiplexing way by working in a transparent way on some sub-frames while working in a non-transparent way on the other sub-frames. The adoption of the method with the coexistence of the transparent transmission and the non-transparent transmission of the relay nodes can effectively reduce the construction cost of a system.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to the design of transparent relay in LTE-Advanced system, the design of coexistence of transparent and non-transparent relay, and the method for realizing compatibility of LTE-advanced system with LTE user equipment through relay nodes. Background technique [0002] 3GPP in its latest standardization document TR36.814 (R1-084256, 3GPP TR 36.814v0.1.1, 3GPP TSG RAN Further Advancements for E-UTRA PhysicalLayer Aspects, 2008-09) on the relay node in the LTE-Advanced system The functions are described accordingly. Among them, according to the information obtained by the user equipment, the relay node can be divided into two types: one is a transparent relay node, and the user equipment connected to the network through the transparent relay node cannot perceive the existence of the relay node; It is a non-transparent relay node, and the user equipment connected to...
