Abstract
A method for data transmission in relay system, includes that: modulation information corresponding to the data of a physical downlink shared channel (PDSCH) is transmitted via a physical downlink control channel (PDCCH) to a user equipment (UE) served by a type 2 relay station; a preset beam-forming processing is performed on the data of the PDSCH, and the processed data of the PDSCH and the dedicated pilot corresponding to the beam-forming processing are transmitted to the UE; an evolved Node B (eNB) directly transmits the common reference signal (CRS) used to demodulate the PDCCH to the UE, and the type 2 relay station does not transmit the CRS to the UE. The present invention also provides concrete structures of the eNB and the type 2 relay station. The application of the present invention can implement concrete data transmission in the system in which the type 2 relay station is introduced.
