Abstract

A method and device for transmitting uplink control information in a wireless communication system supporting carrier aggregation and operating in TDD are discussed. The method includes transmitting hybrid automatic repeat request acknowledgements (HARQ-ACKs) feedback bits o(0),o(1),o(2),o(3) on a physical uplink shared channel (PUSCH), wherein the HARQ-ACKs feedback bits corresponds to HARQ-ACK(0), HARQ-ACK(1), HARQ-ACK(2), and HARQ-ACK(3) associated with a first component carrier (CC) and HARQ-ACK(0), HARQ-ACK(1), HARQ-ACK(2), and HARQ-ACK(3) associated with a second CC.
