Title
(EN) METHOD AND APPARATUS FOR TRANSCEIVING UPLINK CONTROL INFORMATION IN A WIRELESS COMMUNICATION SYSTEM
Abstract
(EN)

The present invention relates to a wireless communication system, and more specifically, to a method and apparatus for reporting channel state information. A method in which a terminal transmits uplink control information (UCI) in a wireless communication system according to one embodiment of the present invention comprises: a step of determining channel state information (CSI) report timing; a step of determining acknowledgement/non-acknowledgement (ACK/NACK) information transmission timing; and a step of transmitting one or more pieces of the CSI or the ACK/NACK information via an uplink subframe. In the event that the CSI is invalid CSI, then said CSI is omitted, and only said ACK/NACK information can be transmitted via the uplink subframe.
