Abstract:
A method for mapping uplink data to a physical uplink shared channel (PUSCH) by a user equipment (UE) in a wireless communication system, the method includes receiving a configuration for a UE-specific aperiodic sounding reference signal (SRS) subframe from a base station; and mapping the uplink data to the PUSCH in the UE-specific aperiodic SRS subframe, wherein the UE-specific aperiodic SRS subframe includes a single carrier frequency division multiple access (SC-FDMA) symbol reserved for an aperiodic SRS, wherein the aperiodic SRS is selectively transmitted in the reserved SC-FDMA symbol to the base station, and the aperiodic SRS is transmitted in the reserved SC-FDMA symbol when triggered by the base station, and wherein the uplink data is mapped to SC-FDMA symbols other than the SC-FDMA symbol reserved for the aperiodic SRS in the UE-specific aperiodic SRS subframe in a case when the aperiodic SRS is not transmitted in the reserved SC-FDMA symbol.
