Radio Node Load Reporting for Resource Aggregation Balancing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current load reporting in wireless communication networks lacks indication of potential resource aggregation performance when cells are used together with other resources, leading to increased signaling load and suboptimal mobility load balancing.
Innovation Solution
A mechanism is introduced where radio network nodes can request and receive update indications on potential resource aggregation measurements from neighboring nodes, allowing for optimized load balancing by negotiating criteria such as thresholds and periodicities for reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If load reporting includes indication of potential resource aggregation performance, then mobility load balancing performance is improved, but signaling load increases
Solution Approach 1:
The patent changes the parameter of load reporting by introducing a new indicator that reflects potential resource aggregation performance. This indicator is calculated based on measurements of resource aggregation potential across multiple cells, and is included in the load reporting messages exchanged between radio network nodes. By changing the reporting parameters to include this aggregated performance metric, the system achieves better load balancing decisions without requiring proportional increases in signaling frequency.
Solution Approach 2:
The patent performs preliminary calculations of resource aggregation potential at the radio network node level before reporting to other nodes. The node pre-computes metrics indicating how well multiple cells can be aggregated together based on their current resource utilization and interference characteristics. This preliminary action reduces the signaling load because the complex aggregation analysis is done locally rather than requiring extensive inter-node communication for each evaluation.
2Measurement precision
If resource aggregation measurements are reported frequently, then load balancing accuracy is improved, but signaling overhead increases
Solution Approach 1:
The patent applies local quality by having each radio network node independently calculate and report its own resource aggregation potential metrics rather than having all nodes report all possible measurements. Each node focuses on reporting quality metrics relevant to its local cell conditions and resource aggregation capabilities. This selective, localized reporting improves measurement precision for relevant parameters while reducing overall signaling overhead by eliminating redundant or less relevant measurements.
3Reliability
If resource aggregation capabilities are considered in load reporting, then multi-connectivity performance is improved, but complexity of load reporting increases
Solution Approach 1:
The patent segments the load reporting process into distinct components: basic load metrics, resource aggregation potential indicators, and multi-connectivity capability information. Each component is calculated and reported separately, allowing receiving nodes to process only the segments relevant to their current needs. This segmentation reduces overall complexity by breaking down the complex aggregation analysis into manageable, modular reporting elements that can be selectively processed.
