Abstract: Embodiments of the present invention disclose an ACK/NACK feedback method in a wireless communication system, including: determining, by a UE, number of public sub-frames, all of which are uplink sub-frame in PCC and any SCC sub-frames of any radio frame in frame structure configurations according to the frame structure configurations of the PCC and any SCC; selecting, by the UE, a configuration, uplink sub-frames of which merely include sub-frames corresponding to the determined number of public sub-frames from existing seven kinds of frame structure configurations; and feeding back, by the UE, to a eNB ACK/NACK information corresponding to PDSCH in the SCC on the PCC adopting a timing relationship between the PDSCH and the ACK/NACK corresponding to the selected configuration. With the ACK/NACK feedback method of the present invention, the UE may adaptively feed back the ACK/NACK according to the configured frame structure configuration of the CC, the carrier aggregation between Bands of different frame structure configurations is effectively supported and the coexistence and performance optimization of different communication systems is implemented without limiting the number of amplifiers of the UE.

Abstract: The present invention provides a UL data transmission method in a wireless communication system, including determining, by the UE, UL virtual resources allocated to the UE by the eNB according to Downlink Control Information (DCI) used for scheduling UL physical resources sent from the eNB to the UE; determining, by the UE, the UL physical resources used for transmitting the UL data after frequency hopping processing in a preset frequency domain when determining that the UL data needs to be processed with frequency hopping processing according to the DCI, if the UL virtual resources allocated to the UE locate at UL sub-frames in a non-aggregation K of any wireless frame, and locate at the preset frequency domain; bearing, by the UE, the UL data and feeding the UL data back to the eNB utilizing the determined UL physical resources which are processed with the frequency hopping processing and used for transmitting the UL data. With the present invention, the PUSCH channel resource collision may be avoided, the frequency diversity gain may be maximized, and the PUSCH performances may be enhanced.
