User equipment reference signal reception quality measurement and early warning method and user equipment

Abstract

The invention provides a user equipment reference signal receiving quality measurement and early warning method for interference coordination. The user equipment receives a radio signal from a neighboring cell to be measured, determines a measurement pattern including multiple subframes, and performs reference signal reception quality measurement on the cell in the multiple subframes to obtain multiple reference signal reception quality measurement samples. The user equipment obtains a reference signal reception quality measurement result by evaluating a plurality of reference signal reception quality samples and applying a weighted average. Among them, the reference signal reception quality samples evaluated as higher utility are given more consideration (for example, given a larger weight), while the reference signal reception quality samples evaluated for lower utility are considered less (for example, given a smaller weight). , or give 0 weight to discard). Through the early warning of the user equipment, the measurement result of the reception quality of the reference signal that is easier to be predicted can be obtained.

Description

[0001] cross reference [0002] This application claims the priority of U.S. Provisional Application No. 61 / 441,744, filed on February 11, 2011, entitled "User Equipment Reference Signal Reception Quality Measurement and Early Warning Method" based on 35 U.S.C. §119, and this application is regarded as refer to. technical field [0003] The present invention relates to wireless network communication, and in particular to enhancing Inter-cell Interference Coordination (ICIC) User Equipment (UE) Reference Signal Received Quality (RSRQ) measurement. Background technique [0004] In the eighth / ninth version of the Long Term Evolution (LTE) standard of the third generation partnership project (3rd Generation Partnership Project, 3GPP), the ICIC is introduced. The basic idea of ​​the ICIC is to implement inter-cell interference control through a radio resource management (Radio Resource Management, RRM) method. ICIC is essentially a multi-cell RRM function, which needs to consi...

Problems solved by technology

[0009] On the other hand, if the application of TDM eICIC for cross-frequency measurement requires measurement restrictions, the UE may need to configure many measurement restrictions, which will lead to high complexity for the UE

Another problem is that for cross-frequency scenarios, when RSRQ measurements have measurement gaps, the resulting measurement opportunities and TDM ICIC constraints may be too few, which will cause greater impact

Even if the RSRQ measurement meets the appropriate measurement constraints, the UE's RSRQ measurement results may still fluctuate greatly due to too few measurement samples
