PURPOSE: A method and an apparatus for downlink physical channel transmission for wireless communication systems with multiple L1 relay nodes are provided to reduce the waste and interference of an L1 relay node by clearly defining the operating characteristics of the L1 delay node. CONSTITUTION: A base station transmits sync data to a certain subframe of a frame, and a relay node stores and transmits base station frame data during a sub timing offset differently determined(503). In a frame section, a terminal obtains synchronization from multi-sync data received from the base station or relay nodes to a different sub frame. |
