Measurement Report Routing in Multi-Connectivity Nodes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-connectivity communication scenarios, there is ambiguity in measurement reporting between Master Nodes (MN) and Secondary Nodes (SNs) due to decentralized measurement configurations, leading to potential misalignment of measurement reports and incorrect network behavior, especially in NR multi-connectivity scenarios with one MN and multiple SNs.
Innovation Solution
A method where network nodes configure the User Equipment (UE) with a clear path and destination for sending measurement reports to either the MN or SNs, eliminating ambiguity by including SRB identity information in measurement configuration messages, allowing for both centralized and decentralized configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If decentralized measurement configuration is used in multi-connectivity, then flexibility and faster local response are improved, but measurement report ambiguity and misalignment occur
Solution Approach 1:
The patent introduces an intermediary mechanism (measurement report routing configuration) that mediates between the decentralized measurement configuration and the centralized measurement report collection. The configuration includes routing information that specifies which node (MN or SN) should receive measurement reports, eliminating ambiguity while preserving the benefits of decentralized configuration.
Solution Approach 2:
The patent segments the measurement report handling into separate paths for different nodes. By configuring separate measurement report routing for MN and SN, the system can independently manage measurement reports from different connectivity nodes, preventing misalignment and ensuring each node receives the correct reports.
2Reliability
If measurement reports are sent to multiple nodes, then comprehensive monitoring is improved, but processing complexity and potential misalignment increase
Solution Approach 1:
The patent segments the measurement report routing by configuring separate paths for different nodes. The measurement configuration includes routing information that specifies which node should receive measurement reports, allowing the system to send reports to multiple nodes (MN and SNs) while maintaining clear separation of responsibilities and preventing processing complexity.
3Measurement precision
If centralized measurement configuration is used, then measurement report alignment is improved, but response time and flexibility are reduced
Solution Approach 1:
The patent segments the measurement configuration into node-specific configurations. Each node (MN and SN) has its own measurement configuration with associated routing information, allowing decentralized, node-specific measurement setups that respond quickly to local conditions while maintaining overall alignment through the routing configuration mechanism.

AI summary
A method performed by a network node for handling measurements in a multi connectivity communication between a User Equipment (UE), and multiple nodes is provided. The multiple nodes include a Master Node (MN), and one or more Secondary Nodes (SNs) in a wireless communication network. The network node is any one out of an MN and an SN. The network node sends at least one configuration to the UE. The at least one configuration comprises any one or more out of a path and a destination for sending a report from the UE to at least one out of the MN and the one or more SNs. The report is to include a result of a measurement according to a measurement configuration, configuring the UE to measure a respective frequency provided by at least one out of the MN and the one or more SNs for communication.
