METHOD AND DEVICE FOR TRANSMITTING AND RECEIVING UPLINK CONTROL INFORMATION IN WIRELESS COMMUNICATION SYSTEM THAT SUPPORTS MULTIPLE CARRIERS

摘要

The present invention relates to a wireless communication system, and more specifically, to a method and a device for transmitting and receiving uplink control information in a wireless communication system that supports multiple carriers. According to one embodiment of the present invention, a method for allowing a terminal to transmit uplink control information (UCI) in a wireless communication system that supports multiple carriers comprises the steps of: receiving one or more uplink grants from a base station; obtaining an indicator which indicates an uplink carrier on which said UCI is transmitted from each of the one or more uplink grants; and transmitting said UCI through a physical uplink shared channel (PUSCH) on the uplink carrier indicated by said indicator, if the one or more uplink grants schedule uplink data transmission on the uplink carrier indicated by said indicator.
