Abstract
Embodiments of the present invention disclose a measurement method based on channel state information-reference signal CSI-RS resources, a base station, a user equipment UE, and a method for inter-cell CSI-RS resource sharing. The measurement method includes: sending, by a first base station, information of at least one CSI-RS configuration set to a user equipment UE; receiving, by the first base station, a result of measurement performed by the UE on a subset or a full set of measurement resources corresponding to the CSI-RS configuration set, wherein the CSI-RS configuration set includes at least two CSI-RS configurations. The technical solution for measurement provided in the embodiments of the present invention implements CSI-RS measurement over multiple CSI-RS configurations, thereby overcoming the problem that REs of a CSI-RS are sparse, and improving the measurement precision of a UE.
