Claim Text:
1. A method for transmitting an uplink signal in a wireless communication system, the method comprising: determining, by a user equipment, a sounding reference signal (SRS) subframe in which a SRS and a physical uplink shared channel (PUSCH) for a first serving cell are simultaneously triggered among a plurality of subframes, the SRS subframe including a plurality of orthogonal frequency division multiplexing (OFDM) symbols; if a SRS transmission on a single OFDM symbol of the SRS subframe for the first serving cell is overlapped with an uplink transmission for a second serving cell, determining, by the user equipment, whether the SRS is actually to be transmitted in the SRS subframe based on a total uplink transmission power; and if the SRS is triggered by a periodic SRS configuration and a plurality of timing advance groups are configured, transmitting, by the user equipment, the PUSCH on remaining OFDM symbols of the SRS subframe for the first serving cell except the single OFDM symbol reserved for the SRS transmission regardless of whether the SRS is actually transmitted by the user equipment in the SRS subframe.
