Solution Overview

Problem

Current wireless communication systems lack an efficient method for managing and exchanging various STA statistical elements, particularly in scenarios where specific conditions need to be met for triggered STA statistical requests and reports, leading to inefficiencies in radio resource measurement procedures.

Innovation Solution

A radio measurement procedure is developed that utilizes group identifier information in STA statistical request frames to efficiently manage and process multiple STA statistical elements, allowing for triggered requests and reports based on predefined conditions, thereby optimizing the exchange of information and reducing unnecessary signaling in wireless networks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If STA statistical elements are continuously monitored and reported without conditions, then measurement completeness is improved, but signaling overhead and system load increase

Engineering Contradiction:
ImproveSTA statistical information completenessVSAvoidsignaling overhead
Core Design Contradiction:
Loss of informationVSLoss of energy

Solution Approach 1:

The patent applies preliminary action by pre-defining triggering conditions and thresholds for STA statistical elements before actual measurement and reporting occurs. The system configures which statistical elements should be monitored and under what conditions they should trigger reports, allowing the network to prepare measurement parameters in advance rather than continuously monitoring all elements without regard to actual needs.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements dynamics by making the reporting mechanism adaptive rather than static. Instead of continuous reporting of all STA statistical elements, the system dynamically triggers reports only when specific conditions are met (such as threshold violations or significant changes in statistical values). This dynamic approach allows the measurement system to adapt its behavior based on actual network conditions and event occurrences.

Inventive Principle:
Principle #15Dynamics

2Measurement precision

If all STA statistical elements are measured and reported, then measurement precision is improved, but processing complexity and time consumption increase

Engineering Contradiction:
ImproveSTA statistics accuracyVSAvoidmeasurement processing time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent applies the extraction principle by selectively extracting only those STA statistical elements that meet predefined triggering conditions for measurement and reporting. Instead of measuring and processing all possible statistical elements continuously, the system extracts and processes only the relevant subset that satisfies specific criteria, such as elements exceeding thresholds or showing significant changes, thereby reducing processing complexity while maintaining measurement precision for critical parameters.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent implements partial action by performing measurements and reporting only for STA statistical elements that require attention based on triggering conditions, rather than exhaustively processing all elements. This partial approach focuses computational resources on the most relevant statistical elements, reducing overall processing time while maintaining adequate measurement precision for network management decisions.

Inventive Principle:
Principle #16Partial or excessive action

3Productivity

If conditional triggering mechanisms are implemented for STA statistical requests, then system efficiency is improved, but device complexity increases

Engineering Contradiction:
Improveradio resource measurement efficiencyVSAvoidmeasurement control complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent applies segmentation by dividing the STA statistical measurement system into distinct functional components: configuration module (defining triggering conditions and thresholds), monitoring module (tracking statistical elements), and reporting module (generating reports when conditions are met). This segmentation allows each component to handle specific tasks independently, improving overall system efficiency while managing complexity through modular design, where each segment can be developed and maintained separately.

Inventive Principle:
Principle #1Segmentation

AI summary

There is provided a radio measurement procedure for station statistics measurements in wireless communication network. In the method, a requesting station transmits to a requested station a triggered station statistics measurements request message including a group identity field which indicates the requested statistics group and a triggered reporting field for station counter which is used to specify trigger conditions comprising reporting triggers and thresholds for the corresponding reporting triggers, wherein the group identity field is set to a predetermined value indicating one group between two groups of station counters, and wherein all subfields for specifying the reporting triggers regarding the other group between the two groups of station counters is set to 0. And the requesting station receives from the requested station a station statistics measurements report message when the trigger conditions specified in the triggered reporting field for station counter of the triggered station statistics measurements request message.
