Method and apparatus for transmitting and receiving signal from relay station in radio communication system
A method and device for a transmitting and receiving a signal from a relay station in a radio communication system is provided. The method includes: receiving offset time information from a base station; configuring a time difference between an access downlink transmission subframe that transmits an access downlink signal to a relay station terminal according to the offset time information and a backhaul downlink reception subframe that receives a backhaul downlink signal from the base station; transmitting a control signal from the access downlink transmission subframe to the relay station terminal; and receiving the backhaul downlink signal from the base station in the backhaul downlink reception subframe..
