Abstract:
Provided are a method and an apparatus for an aperiodic transmission of a sounding reference signal (SRS), which is performed by a user equipment (UE), in a wireless communication system. The UE aperiodically transmits an SRS through a certain uplink (UL) component carrier (CC) of a plurality of UL CCs. The determination of the certain UL CC is based on a downlink (DL) grant, wherein the downlink grant contains a message that triggers the aperiodic transmission of the SRS.
