    Abstract: A method and a user equipment (UE) are provided for transmitting uplink data in a wireless communication system. Uplink data is mapped to resource elements corresponding to a physical uplink shared channel (PUSCH) in a UE-specific aperiodic sounding reference signal (SRS) subframe. The UE-specific aperiodic SRS subframe includes a single carrier frequency division multiple access (SC-FDMA) symbol reserved for an aperiodic SRS. The aperiodic SRS is transmitted in the reserved SC-FDMA symbol when triggered by a base station. The uplink data is not mapped to the SC-FDMA symbol reserved for the aperiodic SRS regardless of whether the aperiodic SRS is transmitted in the reserved SC-FDMA symbol or not. The mapped uplink data is transmitted to the base station via the UE-specific aperiodic SRS subframe.

    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.
