Abstract  Abstract

An apparatus and a method for feeding back data receiving status applied to a Long Term Evolution-Advanced (LTE-A) system are provided. The method includes sequencing by a User Equipment (UE) downlink subframes for transmitting data with respect to each Component Carrier (CC) generating receiving status feedback information for the first X downlink subframes with respect to each CC according to the result of the sequencing where X?M wherein M is the number of downlink subframes on each CC and transmitting the receiving status feedback information generated with respect to each CC to a base station. Accordingly the UE will not misinterpret the receiving status for the downlink subframes due to inconsistencies with the base station between transmitting and receiving feedback. This affects the Hybrid Automatic Repeat Request (HARQ) transmission saves the uplink overheads occupied by the receiving status feedback information and increases the uplink coverage area.
