DATA TRANSMISSION METHOD AND DEVICE IN WIRELESS COMMUNICATION SYSTEM

摘要

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.

1. A method for transmitting, by a user equipment (UE), uplink data in a wireless communication system, the method comprising:
mapping uplink data to resource elements corresponding to a physical uplink shared channel (PUSCH) in a UE-specific aperiodic sounding reference signal (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 transmitted in the reserved SC-FDMA symbol when triggered by a base station, and wherein 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; and transmitting the mapped uplink data to the base station via the UE-specific aperiodic SRS subframe.
