Abstract:
Provided are a method and an apparatus for transmitting ACK/NACK in a time division duplex (TDD)-based wireless communication system. A terminal receives zero or more downlink transmission blocks in M downlink subframes from a first serving cell, and determines an ACK/NACK state {HARQ-ACK(1),HARQ-ACK(2),HARQ-ACK(3),HARQ-ACK(4)} for the first serving cell. The terminal determines an ACK/NACK response based on said ACK/NACK state, and transmits the ACK/NACK response in an uplink subframe.
