Abstract

The embodiment of the invention provides a reference signal notification method comprising the step as follows: network equipment sends a reference signal notification message that comprises time resource information of a reference signal. By using the method provided by the embodiment of the invention, the reference signal informs user equipment of a reference signal configuration message, particularly information related to a CSI-RS, so that the network equipment flexibly provides the reference signal, particularly flexibly provides the CSI-RS, and thus the UE can more efficiently receives the reference signal, particularly the CSI-RS.

Description

technical field [0001] The present invention relates to the communication field, in particular to a reference signal notification method. Background technique [0002] The radio resource management (English full name can be: Radio Resource Management, English abbreviation can be RRM) method of the existing LTE system adopts the measurement method based on the downlink signal, that is, the base station sends a downlink reference signal, such as a cell-specific reference signal with a fixed time-frequency position (English full name can be: Cell Specific Reference Signal, English abbreviation can be: CRS), UE measures the reference signal received power sent by the base station (English full name can be: ReferenceSignal Received Power, English abbreviation can be: RSRP) / reference signal reception Quality (English full name can be: Reference Signal Received Quality, English abbreviation can be: RSRQ) and other measurement results are reported to the base station, and the base s...
