Abstract

The present invention provides a method and an apparatus for feedback transmission in a wireless communication system. A terminal receives downlink control information from a base station and transmits to the base station event-driven feedback information over a first feedback channel. The downlink control information includes information about a short-term feedback period that corresponds to a short period of time for transmitting feedback information and information about a long-term feedback period that corresponds to a long period of time for transmitting feedback information, and the event-driven feedback information is transmitted on the basis of the long-term feedback period.
