COMMUNICATION METHOD AND APPARATUS FOR CARRIER AGGREGATION SYSTEM |
摘要 |
Embodiments of the present invention provide a communication method for a carrier aggregation system. The communication method includes receiving physical downlink share channel PDSCH information sent by a base station through a subframe n of a secondary cell. If a subframe n of a primary cell is a downlink subframe, an ACK/NACK of the sent PDSCH information is fed back on a subframe m or a subframe p of the primary cell. |

1. A communication method for a carrier aggregation system, the method comprising:
receiving, by a user equipment (UE), downlink information from a base station through a subframe n of a secondary cell; and feeding back, by the UE, an ACK/NACK of the downlink information on a subframe m of a primary cell; wherein n and m are subframe indexes; wherein a subframe n of the primary cell comprises a downlink subframe; wherein an index value of the subframe m of the primary cell is equal to an index value of an uplink subframe which is determined according to an ACK/NACK timing relationship to which the subframe n of the primary cell corresponds; and wherein the primary cell and the secondary cell have different UL-DL configurations. |
