Abstract: Provided is a method for transmitting and receiving a signal by a terminal supporting dual-connectivity between evolved universal terrestrial radio access (E-UTRA) and new radio (NR). In the method, when the terminal is configured to aggregate at least two carriers and when the at least two carriers include one of E-UTRA operating bands 1, 3, 19, and 21 and at least one of NR operating bands n78 and n79, an uplink center frequency of a first carrier among the at least two carriers is a first value and a downlink center frequency of the first carrier is a second value, a predetermined maximum sensitivity degradation (MSD) is applied to a reference sensitivity used for reception of the downlink signal.

Abstract: When a terminal aggregates three downlink carriers by using the carrier aggregation (CA) of the LTE-A technology and transmits an uplink signal on two uplink carriers while aggregating at least two uplink carriers, a harmonic component and an intermodulation distortion (IMD) component are generated, thereby influencing a downlink band of the terminal itself. Therefore, the present specification presents a scheme therefor.
