Abstract: A control information sending method, receiving method, and device are provided. The control information sending method includes: determining a first subframe of a first radio frame on a first carrier, where the first subframe includes a control region; sending control information in the control region of the first subframe of the first radio frame to a user equipment, where the control information includes a PDCCH; and sending an ePDCCH in a second subframe of the first radio frame to the user equipment. According to the embodiments of the present invention, when control information borne on an ePDCCH cannot be sent in a first radio frame, a PDCCH can still be sent to a user equipment through a control region in a first subframe, thereby achieving purposes of performing uplink/downlink scheduling for the user equipment and downlink feedback for uplink data of the user equipment.

Abstract: Embodiments of the present disclosure provide a data transmission method, a user equipment, and a base station. The method includes: obtaining a resource element (RE) configuration, where an RE indicated by the RE configuration is a subset of the RE available for sending a channel state information reference signal (CSI-RS) and is the RE onto which a data symbol can be mapped; and receiving, according to the RE configuration, the data symbol that is sent by a base station on the RE indicated by the RE configuration. In some embodiments, a data symbol can be mapped onto the RE that is used for sending the CSI-RS, so that a UE can receive the data symbol on the RE that is used for sending the CSI-RS, thereby improving the utilization efficiency of the RE.
