METHOD FOR TRANSMITTING REFERENCE SIGNAL OF RELAY NODE USING CONTROL CHANNEL ELEMENTS

摘要

PURPOSE: A reference signal transmission method of a relay using a control channel element for efficiently confirming resources used in the relay is provided to easily perform the relay in an LTE-A system by transmitting public reference signal of the relay. CONSTITUTION: A BS(Base Station) registers CCE(Control Channel Element) for transmitting the reference signal of the relay(S410). The relay transmits the information about CCE(S420). The information is promised between system and terminal in the initial setting. The information is transmitted from the separate signaling to the terminal. A reference signal is transmitted in CCE reserved for relay(S430).
