Abstract:
A method for transmitting, by a user equipment (UE), an aperiodic sounding reference signal (SRS) in a wireless communication system; and the UE are discussed. The method includes receiving a downlink control information (DCI) format, which schedules a physical uplink shared channel (PUSCH) and includes an SRS request for triggering transmission of an aperiodic SRS, from a base station (BS); detecting the SRS request; and transmitting, when the UE is not configured with a carrier indicator field (CIF), the aperiodic SRS to the BS on a first uplink (UL) component carrier (CC) in which the PUSCH is scheduled, or, when the UE is configured with the CIF, the aperiodic SRS to the BS on a second UL CC in which the PUSCH is scheduled with a value of the CIF.
