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.
