There is provided a method for transmitting/receiving a signal in carrier aggregation. The method may comprise: transmitting an uplink signal by using two uplink carriers when three downlink carriers and two uplink carriers are configured to be aggregated. The three downlink carriers include three operating bands among evolved universal terrestrial radio access (E-UTRA) operating bands 1, 2, 3, 5, 12, 30 and 40 and the two uplink carrier includes two operating bands thereamong. The method may comprise: receiving a downlink signal through all of three downlink carriers. Here, a predetermined maximum sensitivity degradation (MSD) is applied to receiving reference sensitivity of the downlink signal, thereby successfully receiving the signal.
