Abstract

The present invention provides a method of configuring a reference signal, UE and eNB. The method comprises determining the reference signal configuration preference set, and sending the information of the reference signal configuration preference set to eNB; UE receives the reference signal transmitted by eNB configuration measurement set, the reference signal configuration measurement set is the eNB according to the reference signal configuration preferred set of information configuration, the reference signal configuration measurement set for UE measurement and feedback channel status information. Embodiments of the present invention may be RRH or base station geographically separated can select a reference signal configuration that matches the optimal actual channel of the UE, thereby enabling the UE to obtain good channel conditions.

Description

technical field [0001] The present invention relates to wireless communication technologies, and in particular to a method for configuring reference signals, user equipment (User Equipment, UE) and evolved Node B (evolvedNodeB, eNB). Background technique [0002] In the existing Long Term Evolution (LTE) version 10 (Release 10, R10), the eNB can notify the UE of the channel state information-reference signal (ChannelStateInformationReferenceSignal, CSIRS) configuration used by the UE through radio resource control (RadioResourceControl, RRC) signaling, and the UE According to the CSIRS configuration, the corresponding channel is estimated and relevant channel state information (ChannelState Information, CSI) is fed back. In the R10 system, usually each cell ID corresponds to a CSIRS configuration, and at this time, the CSIRS can be configured for the UE according to the cell ID. [0003] In the heterogeneous network deployment scenario newly introduced by LTETER11, the same...
