Data transmission method and device in wireless communication system

摘要

A data transmission method and device are provided in a wireless communication system. A user equipment transmits uplink data using a first physical uplink shared channel (PUSCH) resource, allocated to a first component carrier (CC) among a plurality of CC's, in a sounding reference signal (SRS) subframe. The plurality of CC's in said SRS subframe includes a single carrier-frequency division multiple access (SRS SC-FDMA) symbol, which is reserved for transmitting SRS.

1. A data transmission method by a user equipment (UE) in a wireless communication system, the data transmission method comprising:
transmitting, by the UE, uplink data to a base station, through a first physical uplink shared channel (PUSCH) and a second PUSCH, in a sounding reference signal (SRS) subframe of each of first and second compment carriers (CCs), respectively, among a plurality of CCs, wherein the SRS subframe of the second CC includes a last single carrier frequency domain multiple access (SC-FDMA) symbol reserved for a transmission of an SRS, wherein, in a case that the uplink data to be transmitted through the first PUSCH in the first CC, and the SRS, to be transmitted in the second CC will coincide in the last SC-FDMA symbol reserved for the transmission of the SRS, the SRS is not transmitted in the second CC, and wherein the transmitting of the uplink data via carrier aggregation comprises transmitting the uplink data via one or more CCs of the plurality of CCs simultaneously, the one or more CCs assigned to the UE according to CC capacity.
