    Abstract: One disclosure of the present specification provides a terminal for transmitting and receiving a signal, the terminal supporting dual connectivity between E-UTRA and NR. The terminal comprises: a transceiver for transmitting an uplink signal and receiving a downlink signal by using the dual connectivity; and a processor for controlling the transceiver, wherein the transceiver is configured to use two of E-UTRA operating bands 1, 3, 18, 21, 28, 41, and 42 and NR operating band n79, and when an uplink center frequency of a first operating band among the E-UTRA operating bands and the NR operating band n79 is a first value and a downlink center frequency of the first operating band is a second value, an MSD is preset, and on the basis of a dual uplink operation, the MSD may be applied to reference sensitivity used for receiving the downlink signal.

    Abstract: One disclosure of the present specification provides a UE. The UE comprises: a transceiver for transmitting a signal and receiving a signal; and a processor to control the transceiver, wherein the UE is a power class 5 UE, wherein the maximum output of the UE is 20 dBm in the n96 band, wherein the transceiver receives a network signal from a base station, wherein, based on the network signal, the processor determines a frequency range of i) 5925 MHz or more and ii) 6425 MHz or less, wherein, based on A-MPR based on the network signal, the processor reduces the maximum output of the UE, wherein, based on the reduced maximum output of the UE, the processor determines transmission power, wherein the transceiver transmits a signal in the frequency range with the determined transmission power, wherein the A-MPR is based on pre-coding, modulation scheme, channel bandwidth, and RB allocation scheme.
