Abstract:
A method for transmitting, by a user equipment (UE), an aperiodic sounding reference signal (SRS) in a wireless communication system. The method includes receiving, via a physical downlink control channel (PDCCH), downlink control information (DCI) including an SRS request for triggering transmission of an aperiodic SRS, detecting the SRS request, if a carrier indicator field (CIF) is configured, transmitting the aperiodic SRS on a uplink (UL) component carrier (CC), among a plurality of UL CCs, corresponding to the CIF, and if a CIF is not configured, transmitting the aperiodic SRS on a UL CC, among the plurality of UL CCs, in which a physical uplink shared channel (PUSCH) is scheduled by the DCI.
