Abstract
One embodiment of the present specification provides a method by which user equipment (UE) transmits an uplink signal according to a spectrum emission mask (SEM). The method comprises a step of transmitting the uplink signal on a plurality of carriers when an RF unit of the UE is set to use inter-band carrier aggregation. Here, when the frequency range of a first SEM of a first carrier overlaps the frequency range of a second SEM of a second carrier, any one SEM allowing a higher power spectral density (PSD) can be selected and applied.
