Abstract

The present invention relates to an apparatus and method for transmitting an uplink signal in a multiple component carrier system. The present invention discloses a user equipment (UE) for transmitting a sounding reference signal (SRS) used to estimate an uplink channel, comprising a reception unit configured to receive serving cell configuration information about a serving cell to be configured in the UE and configured to receive an activation indicator to instruct activation or deactivation of the serving cell, an SRS transmission processing unit configured to trigger the transmission of the SRS in the serving cell when the activation indicator is received in an nth subframe, and a transmission unit configured to aperiodically transmit the SRS in a predefined (n+m)th subframe based on a specific criterion. According to the present invention, uplink scheduling can be precisely performed because a delay in the transmission of the ASRS is reduced.
