Wireless Device Measurement Reporting Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Measurement reporting in wireless networks is often delayed, leading to out-of-date information for handover decisions and unnecessary load on the network, as wireless devices send reports to higher layer nodes even when they can be evaluated by lower layer nodes, which are closer and faster.
Innovation Solution
Configuring wireless devices with a predefined list of coverage objects to send measurement reports to lower layer nodes for objects within the list, while sending reports to higher layer nodes for objects outside the list, allowing lower layer nodes to evaluate and act on timely measurements and reducing unnecessary higher layer processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless devices send measurement reports to higher layer nodes for all coverage objects, then complete measurement information is obtained, but network load increases and latency increases
Solution Approach 1:
The patent segments the measurement reporting process by dividing coverage objects into two categories: those within a predefined list (reported to lower layer nodes) and those outside the list (reported to higher layer nodes). This segmentation allows the system to distribute reporting responsibilities appropriately, reducing unnecessary higher layer processing while maintaining complete measurement information capture.
Solution Approach 2:
The patent applies local quality by enabling lower layer nodes to handle measurement reports for specific coverage objects (those in the predefined list) locally, without requiring higher layer node processing. This local handling reduces network load and latency for routine measurements while higher layer nodes retain authority for exceptional cases.
2Extent of automation
If measurement reports are sent to higher layer nodes, then centralized control is maintained, but handover decision latency increases
Solution Approach 1:
The patent segments control authority between lower layer nodes and higher layer nodes based on coverage object identification. Lower layer nodes autonomously handle handover decisions for coverage objects in the predefined list, while higher layer nodes maintain centralized control for objects outside the list. This segmentation enables rapid local decisions without sacrificing overall system control.
Solution Approach 2:
The patent implements preliminary action by pre-configuring a list of coverage objects at lower layer nodes, enabling these nodes to immediately recognize and process measurement reports for familiar coverage objects without waiting for higher layer node instructions. This pre-prepared knowledge base reduces decision latency while maintaining centralized oversight.
3Stability of the object's composition
If all measurement reports are processed by higher layer nodes, then unified measurement evaluation is ensured, but unnecessary network load is created
Solution Approach 1:
The patent segments the measurement evaluation function between lower layer nodes and higher layer nodes. Lower layer nodes perform evaluation for coverage objects in their predefined list, while higher layer nodes evaluate objects outside the list. This segmentation maintains evaluation consistency within each segment while significantly reducing the processing load on higher layer nodes.
Solution Approach 2:
The patent enables lower layer nodes to serve themselves by autonomously evaluating measurement reports for coverage objects in their predefined list without requiring higher layer node intervention. This self-service capability reduces network load and energy consumption while maintaining measurement evaluation consistency through standardized evaluation criteria.

AI summary
A wireless device (400), a higher layer node (404) and methods therein, for handling measurement reporting in a wireless network as performed by the wireless device (400). The wireless device (400) detects (4:1) a coverage object being a cell or a beam not contained in a predefined first list of coverage objects for which the wireless device (400) is required to send measurement reports to a lower layer node (402) operable according to at least one of layer 1 and layer 2. The wireless device (400) then measures a radio signal of the coverage object where the measured radio signal fulfils a predefined event condition, and sends (4:2B) a measurement report of said measuring to a higher layer node (404) operable according to one or more layers above layer 1 and layer 2.
