DATA TRANSMISSION METHOD, BASE STATION AND USER EQUIPMENT

摘要

A data transmission method, a base station and user equipment are disclosed in the present invention. The method comprises: if a scheduling sub-frame satisfying a Hybrid Automatic Repeat reQuest (HARQ) timing relationship with a first common sub-frame is a special sub-frame, then determining to send Downlink Control Information (DCI) to User Equipment (UE) in a second common sub-frame before the scheduling sub-frame, wherein the DCI is used for scheduling uplink data transmission in the first common sub-frame; sending the DCI to the UE in the second common sub-frame; and receiving the uplink data that the UE sends in the first common sub-frame on the basis of the DCI. In accordance with the data transmission method in an embodiment of the present invention, the base station performs scheduling of and feedback to the UE in the common sub-frame in the case that the special sub-frame exists, so that the problem that normal data transmission can not be performed between the UE and the base station due to the existence of the special sub-frame can be solved, thus improving system performance and user experience.
