Radio Cell Resource Status Information via Spatial Partitioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cell-specific Composite Available Capacity (CAC) metrics in LTE systems fail to accurately represent available capacity in cells with MIMO transmission capabilities, and they do not provide information on the spatial distribution of load/available capacity within a cell.
Innovation Solution
A method is proposed where a first network node determines resource status information by calculating a ratio between the resource status of a radio cell and its partitions, and then transmits this information to a second network node. This allows for the estimation of available capacity in different regions of a radio cell's coverage area.

Engineering Contradiction Analysis
1Loss of information
If cell-specific Composite Available Capacity (CAC) metrics are used in LTE systems, then overall cell capacity information is provided, but the spatial distribution of load/available capacity within the cell is not revealed and MIMO transmission capabilities are not accurately represented
Solution Approach 1:
The patent segments the cell's coverage area into multiple spatial partitions (e.g., sectors, beams, or geographic regions) and calculates resource status information separately for each partition. This segmentation enables the system to provide detailed spatial distribution information about load and available capacity, resolving the information loss problem while maintaining manageable complexity through structured data organization.
Solution Approach 2:
The patent applies local quality by providing differentiated resource status information for different spatial partitions within the same cell. Each partition can have its own CAC metrics that reflect local conditions, allowing the system to accurately represent MIMO transmission capabilities in specific directions or regions while maintaining overall cell-level aggregation when needed.
2Measurement precision
If SSB-beam specific resource status information is collected for each partition, then finer granularity load assessment is achieved, but the complexity of measuring and reporting increases
Solution Approach 1:
The patent segments measurement tasks by associating each SSB beam with a specific spatial partition and measuring resource status independently for each partition. This approach enables precise load assessment at the beam level while organizing measurements in a structured manner that reduces overall complexity through modular processing.
Solution Approach 2:
The patent introduces spatial partitions as intermediary entities between the cell level and individual SSB beams. Each partition aggregates information from multiple beams, serving as a intermediate layer that reduces the total number of measurements required while maintaining fine-grained assessment capabilities. This intermediary structure simplifies the measurement and reporting process.

AI summary
The present disclosure relates to telecommunications. In one of its aspects, the disclosure concerns a method, performed by a first network node, for providing resource status information to a second network node. The first network node controls a radio cell comprising a plurality of partitions. The method comprises determining a resource status information based on a ratio between a resource status associated to the radio cell and a resource status associated to at least one partition of the radio cell. The method further comprises transmitting, to the second network node, a resource status update message comprising at least one information element comprising the determined resource status information.
