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 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.

Abstract: There is provided a method for transmitting/receiving a signal. The method may be performed by a wireless terminal and comprise: transmitting, by the wireless terminal configured with a carrier aggregation, an uplink signal. The carrier aggregation may include a combination of a evolved universal terrestrial radio access (E-UTRA) operating band 46 and one of E-UTRA operation bands 5, 7, 8, 21, 28 and 41. The method may comprise: receiving a downlink signal. If the uplink signal is transmitted through one of E-UTRA operation bands 5, 7, 8, 21, 28 and 41 and if the downlink signal is received through the E-UTRA operating band 46, a predetermined maximum sensitivity degradation (MSD) is applied to receiving reference sensitivity of the downlink signal, thereby successfully receiving the 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 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.
