1. A method for transmitting/receiving data by a first relay node in a wireless communication system, the method comprising:
receiving configuration information from a network node,
wherein the configuration information includes a timing offset for transmitting downlink data; and
transmitting, to a second relay node, the downlink data based on the configuration information,
wherein transmission timing of the downlink data is determined based on the timing offset and a timing advance (TA), and
wherein, based on that uplink transmission and downlink transmission are performed by using the Time Division Multiplexing (TDM) method through a backhaul link or an access link, a transmission gap for matching a boundary between symbols is inserted between the uplink transmission and the downlink transmission.
