Abstract
The invention relates to a method for transmitting an uplink signal and feedback information of a relay, and to a relay apparatus using the method. The relay can receive information, constituting a downlink backhaul subframe and an uplink backhaul subframe from a base station. The relay can transmit an uplink signal via the relevant uplink backhaul subframe on the basis of the received information constituting the uplink backhaul frame. Further, the relay can receive a downlink reference signal from the base station, measure the status of a channel, and transmit the status of the channel in values, in various formats and in various points in time and cycles, to the base station.
