A method and device for transmitting an uplink signal in a wireless communication system A user equipment (UE) sets up a sounding reference signal (SRS) configuration for a first serving cell, the SRS configuration including information for an SRS transmission, and determines an SRS subframe in which an SRS and a physical uplink shared channel (PUSCH) for the first serving cell are simultaneously triggered among a plurality of subframes according to the SRS configuration. The SRS subframe includes a plurality of orthogonal frequency division multiplexing (OFDM) symbols. If an SRS transmission on the SRS subframe for the first serving cell is overlapped with an uplink transmission for a second serving cell, determining, by the UE, whether the SRS is actually to be transmitted in the SRS subframe based on a total uplink transmission power. |

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