Patent ID: 8665776

Claim:
A method for data transmission, the method comprising: sending, according to a mapping relationship between a first high-speed downlink shared channel (HS-DSCH) radio network temporary identity (H-RNTI) of a user equipment and a second H-RNTI of a relay node accessed by the user equipment, data to the user equipment corresponding to the first H-RNTI by using the relay node corresponding to the second H-RNTI; wherein the sending, comprises: obtaining, by a radio network control device, a prestored mapping relationship between the first H-RNTI of the user equipment and the second H-RNTI of the relay node accessed by the user equipment; and sending, by the radio network control device according to the mapping relationship, the first H-RNTI, the second H-RNTI and the data to an access device so that the access device sends the data to the user equipment corresponding to the first H-RNTI by using the relay node corresponding to the second H-RNTI.
