Ack/nack feedback method in wireless communication system

摘要

Disclosed is a method for transmitting feedback information by a terminal in a wireless communication system employing time division duplex (TDD). The method comprises a user equipment (UE) receives a first subframe configuration information of a primary cell (PCell) from a base station. The UE also receives a second subframe configuration information of a secondary cell (SCell) from the base station. The UE then receives data on the SCell and determines feedback timing based on the first subframe configuration information and the second subframe configuration information. The UE transmits feedback information corresponding to the data based on the determined feedback timing to the base station. The first subframe configuration information is different from the second subframe configuration information.
