Method for configuring a backhaul link subframe in a wireless communication system to which a carrier aggregation scheme is applied and an apparatus for the same

A method for processing signals at a user equipment (UE) in a Time Division Duplex (TDD) wireless communication system, the method comprising:

• receiving, from a base station (BS), a control signal in a downlink subframe via a first cell configured with a first subframe configuration;
• receiving, from the BS, a data signal based on the control signal in the downlink subframe via a second cell configured with a second subframe configuration that is a different subframe configuration than the first subframe configuration;
• and
• transmitting, to the BS in an uplink subframe, a response signal corresponding to the data signal,
• wherein a relationship between the downlink subframe and the uplink subframe is defined based on the first subframe configuration.
