A disclosure of the present specification provides a user equipment (UE). The UE comprises: a transceiver unit for transmitting or receiving a signal; and a processor for controlling the transceiver unit, wherein: the transceiver unit may include two transmitters; the UE may have a maximum output of 29 dBm; the processor may determine transmission power on the basis of a configured maximum power reduction (□PR); the □PR may be configured on the basis of edge RB allocations, outer RB allocations, and inner RB allocations; the □PR may be configured on the basis of DFT-s-OFDM and CP-OFD□; the □PR may be configured on the basis of Pi/2 BPSK, QPSK, 16 QA□, 64 QA□, and 256 QA□; and the transceiver unit may transmit a signal to a base station by using the two transmitters on the basis of the determined transmission power.
