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 and device for transmitting a power headroom report (PHR) by a user equipment (UE) in a communication system supporting a plurality of carriers. The method includes transmitting, to an eNode B (eNB), a power headroom report (PHR) related to the plurality of carriers configured for the UE. The power headroom report (PHR) comprises a first type power headroom (PH) and a second type power headroom (PH). While the first type power headroom (PH) is calculated for a power headroom report (PHR) related to a primary carrier and a non-primary carrier, the second type power headroom (PH) is calculated for a power headroom report (PHR) related to only the primary carrier. The second type power headroom (PH) is calculated for case of simultaneous transmission of a physical uplink control channel (PUCCH) and a physical uplink shared channel (PUSCH).
