METHOD AND DEVICE FOR PROCESSING HARQ FEEDBACK IN A MOBILE COMMUNICATION SYSTEM

摘要

A device and method for handling HARQ feedback in a mobile communication system are disclosed. The HARQ feedback handling method includes: analyzing a control message from a base station to recognize presence of HARQ feedback relationships between downlink carriers and uplink carriers; determining an uplink carrier (a downlink carrier) to support HARQ feedback in response to downlink traffic (uplink traffic) sent through a downlink carrier (an uplink carrier); and sending (receiving) HARQ feedback through the determined uplink carrier (downlink carrier).

主权项

1. A method by a terminal, the method comprising:
receiving uplink resource allocation information on a first uplink carrier of a first cell via a second downlink carrier of a second cell, the first cell including the first uplink carrier and a first downlink carrier; transmitting uplink data based on the uplink resource allocation information via the first uplink carrier; and receiving feedback information corresponding to the uplink data via the second downlink carrier of the second cell.
