Abstract

The present invention discloses a data transmission method, base station and user equipment. The method includes: if the scheduled subframe that satisfies the hybrid automatic repeat request (HARQ) timing relationship with the first normal subframe is a special subframe, determine the Sending downlink control information DCI to the user equipment UE on the second normal subframe before the scheduled subframe, where the DCI is used to schedule uplink data transmission on the first normal subframe; The UE sends the DCI; and receives the uplink data sent by the UE in the first normal subframe according to the DCI. According to the method for transmitting data in the embodiment of the present invention, in the case that special subframes exist, the base station can solve the problem caused by the existence of special subframes between the UE and the base station by scheduling and feeding back the UE on normal subframes. In order to improve the system performance and user experience.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and more specifically, to a method for transmitting data, a base station, and user equipment. Background technique [0002] In the Long Term Evolution (referred to as "LTE") system, when the base station needs to schedule a certain user equipment, it will send a message to the user equipment (User Equipment, referred to as "UE") on the downlink. Downlink Control Information (Downlink Control Information, "DCI" for short), the DCI may schedule the UE to perform data transmission on the uplink, and may also schedule the UE to perform data reception on the downlink. For uplink scheduling, if the UE receives DCI sent by the base station on subframe n and the DCI is used to schedule uplink transmission, the UE will send uplink data to the base station on subframe n+k. Frame n+k and subframe n satisfy the hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, referred to ...
