Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current load reporting mechanisms in wireless communication networks lack indications for potential resource aggregation, leading to increased signaling load and suboptimal mobility load balancing decisions.

Innovation Solution

Introduce a mechanism where radio network nodes can request and receive update indications on potential resource aggregation from neighboring nodes, negotiating criteria such as thresholds and periodicities to optimize load balancing and reduce signaling load.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If current load reporting mechanisms are used without resource aggregation indications, then signaling load is reduced, but mobility load balancing decisions become suboptimal

Engineering Contradiction:

Improvemobility load balancing decision qualityVSAvoidsignaling load

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent extracts only the necessary resource aggregation indication information from complete load reports. Instead of transmitting full load reports for all cells, the system selectively includes resource aggregation status indicators only when relevant, thereby reducing signaling overhead while maintaining decision quality.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The load reporting mechanism is enhanced to serve multiple functions simultaneously: it continues to provide traditional load information while also indicating resource aggregation potential. This multi-functionality allows the same signaling channel to support both existing load balancing operations and new resource aggregation awareness without requiring separate dedicated signaling channels.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If resource aggregation information is continuously reported, then mobility load balancing performance is improved, but signaling overhead increases

Engineering Contradiction:

Improveload balancing performanceVSAvoidsignaling overhead

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

Resource aggregation indication reporting is implemented as a periodic or event-triggered action rather than continuous reporting. The system reports resource aggregation status at defined intervals or when changes occur, reducing signaling overhead while ensuring load balancing decisions are based on sufficiently current information.

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

The system applies partial reporting by including resource aggregation indications only for specific cells or under specific conditions rather than reporting all available information continuously. This selective approach provides sufficient information for effective load balancing while minimizing unnecessary signaling overhead.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

Embodiments herein disclose, for example, a method performed by a first radio network node (12) for handling communication in a wireless communication network. The first radio network node transmits to a second radio network node (13), a request for retrieval of an update indication of measurement upon a potential resource aggregation of one or more cells controlled by the second radio network node (12).
