Method for transmitting control information and apparatus therefor
The present invention relates to a wireless communication system. More particularly, the present invention relates to a method for transmitting uplink control information in a wireless communication system that supports carrier aggregation and operates in a TDD system, and to an apparatus therefor. The system comprises the steps of: generating a first set of hybrid automatic repeat request acknowledgement (HARQ-ACK) associated with a first component carrier (CC); generating a second set of HARQ-ACK associated with a second CC; and transmitting 4-bit information corresponding to the first set of HARQ-ACK and the second set of HARQ-ACK on a physical uplink shared channel (PUSCH).
1. A method for transmitting uplink control information in a wireless communication system supporting carrier aggregation and operating in TDD, the method comprising:
