Abstract  Abstract

An embodiment of the present invention provides a communication method for a Carrier Aggregation (CA) system which relates to the technical field of communications. The communication method comprises: receiving Physical Downlink Shared Channel (PDSCH) information delivered by a base station through a sub-frame n of a Secondary Cell (SCell); and if a sub-frame n of a Primary Cell (PCell) is a downlink sub-frame performing ACK/NACK feedback on a sub-frame m or a sub-frame p of the PCell for the delivered PDSCH information m being the sub-frame index of a sub-frame of ACK/NACK fed back by the PCell according to an ACK/NACK timing relationship corresponding to the sub-frame n of the PCell for the PDSCH of the sub-frame n of the PCell and p being a sub-frame index of a sub-frame of ACK/NACK fed back by the SCell according to an ACK/NACK timing relationship corresponding to the sub-frame n of the SCell for the PDSCH of the sub-frame n of the SCell. The present invention is applicable to a CA system and can effectively ensure normal communication between a base station and a user equipment.
