Disclosed is a method for transmitting data by a user equipment (UE) in a wireless communication system including receiving scheduling information for scheduling a plurality of uplink (UL) subframes, identifying a UL subframe u among the plurality of UL subframes, determining a first transmit power for a physical uplink shared channel (PUSCH) in the UL subframe u, selecting a transmit power among the first transmit power and a predetermined second transmit power, and transmitting data through the PUSCH in the UL subframe u using the selected transmit power, wherein the first transmit power is determined based on a first power adjustment factor for a UL subframe (u−1), in case that the UL subframe u is different from a first scheduled UL subframe among the plurality of UL subframes, and wherein the first transmit power is determined based on a second power adjustment factor for the UL subframe u, in case that the UL subframe u is the first UL subframe.
