The present invention provides a method for configuring a reference signal, a UE, and an eNB. The method includes: determining, by a UE, a reference signal configuration priority set, and sending information of the reference signal configuration priority set to an eNB; and receiving, by the UE, a reference signal configuration measurement set sent by the eNB, where the reference signal configuration measurement set is configured by the eNB according to the information of the reference signal configuration priority set, and the reference signal configuration measurement set is used for the UE to measure and feed back channel state information. In embodiments of the present invention, a reference signal configuration matched with an optimal actual channel of a UE can be selected when an RRH or a base station is geographically separated, so that the UE can acquire a good channel condition.
