Claim:
1. A method of reducing transmission power, the method performed by a UE (User Equipment) and comprising: determining whether a plurality of uplink signals are transmitted through a plurality of uplink carriers in a uplink band of a band 25 among E-UTRA (Evolved-Universal Terrestrial Radio Access) operating bands; determining whether the plurality of uplink carriers are non-contiguously aggregated in intra-band; determining transmission power for transmitting the plurality of uplink signals by applying a maximum power reduction (MPR); and applying an additional MPR to the determined transmission power for protecting an uplink band of a band 2 from unwanted emission of the band 25, wherein the uplink band of the band 25 is a band from 1850 MHz to 1915 MHz, wherein the uplink band of the band 2 is a band from 1850 MHz to 1910 MHz, wherein the additional MPR is obtained by CEIL {M where N
