| 摘要 |
The present invention relates to a wireless communication system, and more particularly, to a method of transmitting feedback, by which a signaling overhead can be efficiently reduced. In receiving a group feedback by a transmitting end in a wireless communication system, the present invention includes transmitting at least one data unit to a receiving end during a prescribed time interval and receiving a group feedback indicating a presence or non-presence of error for the overall at least one data unit from the receiving end. Accordingly, a transmitting/receiving end of a communication system transceives a group feedback for multiple feedbacks indicating an error presence or non-presence of overall data received in TTI, thereby reducing a signaling overhead.
