Wireless Measurement Reporting for Serving Cell Quality
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, particularly in LTE-A, reporting measurement results for multiple serving cells can be inefficient due to limited radio resources, as all serving cells' information is not always necessary for the base station, leading to potential unnecessary data transmission.
Innovation Solution
A method and apparatus that configure multiple serving cells, including at least one primary and one secondary cell, to selectively report measurement results based on a supplementary threshold, transmitting only the quality of the best neighboring cell when the serving cell's quality falls below this threshold, thereby reducing message size and preventing unnecessary information transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If measurement results for all serving cells are reported to the base station, then the base station can set optimal serving cells based on comprehensive information, but radio resources are wasted due to unnecessary data transmission
Solution Approach 1:
The patent extracts only the necessary measurement information from the complete set of serving cells. Specifically, it identifies and reports measurement results only for secondary cells where the serving cell quality is below a supplementary threshold, separating essential information from redundant data to reduce reporting overhead while maintaining decision-making accuracy
Solution Approach 2:
The patent applies different reporting criteria to different cells based on their quality characteristics. Primary cells and secondary cells with good quality (above supplementary threshold) use standard reporting rules, while secondary cells with poor quality (below supplementary threshold) trigger additional measurement reporting. This localized differentiation optimizes resource usage by focusing reporting efforts where needed
2Loss of information
If measurement results for multiple serving cells are reported, then comprehensive information is provided for base station decision-making, but the message size increases leading to inefficient resource usage
Solution Approach 1:
The patent extracts only the necessary measurement information from the complete set of serving cells. Specifically, it identifies and reports measurement results only for secondary cells where the serving cell quality is below a supplementary threshold, separating essential information from redundant data to reduce reporting overhead while maintaining decision-making accuracy
Solution Approach 2:
The patent applies partial action by reporting measurement information selectively rather than completely for all cells. It triggers additional measurement reporting only when necessary (when secondary cell quality falls below supplementary threshold), providing just enough information for optimal decision-making without the overhead of comprehensive reporting

AI summary
The present invention relates to a method and apparatus for reporting a measurement result in a wireless communication system. A terminal configures a plurality of serving cells, and performs measurement on the plurality' of serving cells. When a measurement report is triggered, the terminal determines whether or not a quality of at least one serving cell from among the plurality of serving cells is lower than an auxiliary' threshold value. The measurement report includes the quality of a best neighboring cell at a serving frequency of the serving cell the quality of which is lower than the auxiliary threshold value.
