Abstract

A method and system for a relay node (RN) implementing random access are provided. The method includes the following steps: after having accessed the network as a user equipment (UE), the RN informs the donor eNB (DeNB) that the RN itself is a relay node; the DeNB triggers the RN to switch from listening the physical downlink control channel (PDCCH) to listening the RN dedicated PDCCH (R-PDCCH). By using the method of the present invention, the data transmission by the RN between a UE served by the RN and the DeNB which the RN belongs to is ensured.
