Abstract: Embodiments of the present disclosure provide a method and a communications system for switching a transmission time interval, user equipment, and an evolved NodeB (eNB). User equipment (UE) calculates a transmission time interval (TTI) switching characteristic parameter, and the UE sends a TTI switching request message if the TTI switching characteristic parameter meets a switching condition. The eNB sends, to the UE, a TTI switching indication message that includes indication information of a second TTI, and the UE performs transmission by using the second TTI. By using the method for switching a TTI, the UE and the eNB described in the embodiments of the present disclosure, a TTI used for transmission can be adjusted in time according to a channel quality change of the UE, thereby remarkably shortening a service delay.
