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 E-UTRA uses at least one of E-UTRA operating bands 1, 3, 5, and 7, when the NR uses one of NR operating bands n77, n78, and n79, when an uplink center frequency of a first operating band among the E-UTRA operating bands and the NR operating bands is a first value, and when a downlink center frequency of the first operating band is a second value, a predetermined maximum sensitivity degradation (MSD) is applied to reference sensitivity used for reception of the downlink signal.
