Abstract: A disclosure of the present specification provides a user equipment (UE) supporting a Dual Connectivity (DC) with Evolved Universal Terrestrial Radio Access (E-UTRA) and New Radio (NR). The UE may include a transceiver configured with the DC and configured to transmit an uplink signal and receive a downlink signal; and a processor configured to control the transceiver. Wherein based on (i) that the E-UTRA includes at least E-UTRA operation band 41, (ii) that the NR includes at least NR operation band 41, and (iii) that a band to be protected is a first band, the transceiver may be configured with a predetermined maximum level of a spurious emission.

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.
