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] see Figure 5 , is a flowchart of a method for RRM measurement for CoMP in LTE provided by the present invention.

[0053] The method includes the following steps.

[0054] In step S100, the base station configures the points in the RRM measurement set and the resource information of the CSI-RS used for the RRM measurement to the terminal.

[0055] In step S200, the terminal measures the RSRP (Reference Signal Received Power) of the CSI-RS for the points in the RRM measurement set according to the CSI-RS resource information, and reports the measurement result.

[0056]Preferably, the step S100 further includes the base station configuring and reporting the trigger event to the terminal;

[0057] The reporting of the measurem...

Abstract

The invention discloses a radio resource management measurement method and a system in long term evolution based on coordinated multiple points. The method comprises the following steps that: a base station configures a concentrated point of radio resource management (RRM) measurement for a terminal and resource information of a channel state indication and reference signal (CSI-RS) used by the RRM measurement; and the terminal measures reference signal received power (RSRP) of the CSI-RS according to the concentrated point of RRM measurement for the CSI-RS information and reports a measurement result. The concentrated point of RRM measurement is configured by employing the base station, and the RRM measurement can be optimized.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and system for radio resource management measurement in long-term evolution. Background technique [0002] In LTE (Long Term Evolution, Long Term Evolution) version 11 (Release 11), a CoMP (Coordinated Multiple Points, coordinated multipoint) technology is introduced. CoMP transmission and reception is considered as a tool to improve high data rate coverage, cell edge throughput and increase system throughput. 3GPP is currently studying and evaluating the performance advantages and standardization impact of CoMP operation. [0003] Wherein, a point is a group of geographically co-located transmitting antennas, and different sectors of the same site site correspond to different points. The CoMP cooperating set is a group of geographically separated points that directly and / or indirectly participate in data transmission to a UE (User Equipment, terminal) on heterogeneous time-f...
