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 control information (UCI) using a physical uplink control channel (PUCCH) 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 second CC which omprises a single carrier-frequency division multiple acces (SRS SC-FDMA) symbol, which is reserved to transmit SRS.
