Embodiment Construction

[0051] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0052] figure 1 It is a flowchart of a configuration method for RRM measurement in the present invention; the method provided by the present invention is applied to the scenario of introducing a new carrier type, such as figure 1 shown;

[0053] In step 101, the base station configures CSI-RS resource information for a newly added carrier type.

[0054] Step 102, the base station selects CSI-RS resource information, configures a CSI-RS function information element used to indicate the measurement purpose of the selected CSI-RS resource information, and configures measurement reporting conditions; the selected CSI-RS resource information, the selected The configured corresponding CSI-RS function information element and measurement rep...

Abstract

The invention discloses a configuration method for RRM measurement. The method is applied to scenes where new carrier type is introduced and characterized in that a base station configures CSI-RS resource information for the new carrier type; the base station selects the CSI-RS information, configures a measuring objective CSI-RS function cell for indicating the selected CSI-RS resource information and configures measurement reporting conditions; the selected CSI-RS information, the configured corresponding CSI-RS function cell and the measurement reporting conditions are notified to UE (unified equipment); the UE carries out corresponding measurement according to the CSI-RS function cell and corresponding CSI-RS resource information notified by the base station; when the measurement reporting conditions are met, the UE sends corresponding measurement reports to the base station, and the base station carries out corresponding process according to the measurement reports sent by the UE. According to the configuration method, RRM measurement in scenes where new carrier type is introduced can be achieved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a configuration method for radio resource management RRM measurement. Background technique [0002] In the multi-carrier aggregation CA of LTE Release 11, a new carrier type (NCT, New Carrier Type) is introduced. From the perspective of RAN 1, the main purpose of introducing NCT for carrier aggregation is to improve spectrum efficiency and energy efficiency, improve the support capability of heterogeneous network HetNet scenarios, better support inter-machine communication scenarios and enhanced multimedia broadcast multicast services ( eMBMS, Enhanced Multimedia Broadcast Multicast Service) services, etc. [0003] At present, for the aggregation between traditional carriers in LTE Rel-10, the RRM measurement is performed through the CRS reference signal, which also brings problems such as low energy efficiency and poor interference coordination effect in HetNet...
