Abstract:
1. A communication method of a terminal that performs feedback as to whether decoding of data packets was successful in a wireless communication system, the method comprising: obtaining an uplink feedback channel comprising resource areas that are respectively mapped to indices of control channel elements (CCEs) that are included in at least two different resource allocation control channels, the CCEs having different respective indices, and the at least two different resource allocation control channels comprising a physical downlink control channel (PDCCH) and an enhanced PDCCH (E-PDCCH); allocating information of whether decoding of a data packet transmitted by a base station was successful, to a resource area of the uplink feedback channel that is mapped to a CCE aggregation in which control information of the data packet is transmitted; and feeding back, to the base station, the information of whether the decoding of the data packet was successful, using the resource area of the uplink feedback channel.
