User Equipment Measurement Reporting for Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, user equipment (UE) experiences high power consumption when transmitting comprehensive measurement results to the network, especially in RRC_IDLE or RRC_INACTIVE states, which is inefficient for adding suitable secondary cells for carrier aggregation or dual connectivity.
Innovation Solution
A method where the UE receives a first indication for measurement from a serving cell, performs neighbor cell measurements, determines valid results based on a preconfigured threshold, and transmits a second indication to the serving cell, allowing for efficient reporting of valid measurement results during RRC connection establishment procedures, thereby reducing unnecessary power consumption and optimizing network resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If UE transmits whole measurement result information to the network, then the network can obtain comprehensive measurement data for adding SCells, but UE power consumption increases significantly
Solution Approach 1:
The patent extracts only the essential information (validity indication based on threshold comparison) from the complete measurement result and transmits it to the network. The UE compares measurement values against preconfigured thresholds and sends only the validity indication rather than the entire measurement dataset, thereby reducing power consumption while preserving necessary information for SCell addition decisions.
Solution Approach 2:
The measurement result information is segmented into two parts: validity indication (transmitted) and detailed measurement values (not transmitted unless requested). This segmentation allows the UE to send only the critical validity flag that enables the network to make SCell addition decisions without processing power-intensive complete measurement reports.
2Loss of information
If UE transmits complete measurement results, then the network has full data for carrier aggregation decisions, but transmission overhead and processing complexity increase
Solution Approach 1:
The patent extracts only the critical validity indication from complete measurement results. The UE determines whether measurement values meet preconfigured thresholds and transmits only this validity flag to the network, reducing reporting complexity while maintaining sufficient information for carrier aggregation and dual connectivity decisions.
3Reliability
If UE performs measurement and reports all results, then suitable SCells can be identified for CA or DC, but UE energy resources are depleted faster
Solution Approach 1:
The patent extracts only the essential validity indication from complete measurement results. The UE compares measurement values against preconfigured thresholds and transmits only the validity flag, enabling reliable SCell selection while minimizing energy consumption during measurement and reporting operations.
Solution Approach 2:
The network preconfigures threshold values before the UE performs measurements. This preliminary action allows the UE to efficiently determine validity during measurement without requiring post-measurement processing or transmission of complete result sets, thereby reducing energy consumption while maintaining reliable SCell identification.
