Split Measurement Configuration for 5G Mobility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current LTE and 5G wireless communication systems face challenges in efficiently managing measurement configurations and mobility procedures across multiple connections, leading to increased latency, resource wastage, and complex mobility handling, particularly in multi-connectivity scenarios.
Innovation Solution
Implementing a split measurement configuration where measurement operations are coordinated between different Radio Resource Control (RRC) connections, allowing user equipment to deliver measurement reports to specific measurement layers, and assigning owner RRC entities for each layer to reduce signaling overhead and optimize mobility management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single unified measurement configuration is used for all connections, then measurement handling is simplified, but mobility management complexity increases and latency increases
Solution Approach 1:
The patent divides the measurement configuration into separate measurement layers, with each layer associated with specific network nodes (e.g., master node and secondary node). This segmentation allows independent measurement handling for different connections, reducing mobility management latency by enabling parallel processing and avoiding centralized bottlenecks.
2Ease of operation
If measurement reports are handled centrally, then coordination is easier, but signaling overhead increases and resource wastage increases
Solution Approach 1:
The patent extracts measurement report handling from centralization and assigns it to specific owner RRC entities associated with each measurement layer. This extraction reduces signaling overhead by eliminating redundant reporting and allows distributed processing, where each node handles only its relevant measurements independently.
3Productivity
If multiple measurement configurations are implemented for different connections, then mobility handling efficiency improves, but device complexity increases
Solution Approach 1:
The patent implements a universal measurement layer framework that can accommodate multiple connections and network nodes through a standardized structure. Each measurement layer follows the same organizational pattern, allowing efficient mobility handling across different connections while managing complexity through reuse of proven templates and protocols.

AI summary
A method and apparatus may include transmitting a measurement split request to a network node. The measurement split request designates a first measurement layer and a second measurement layer. The first measurement layer corresponds to a measurement configuration for the apparatus. The second measurement layer corresponds to a measurement configuration for the network node. The method may also include receiving an acknowledgement that the measurement split request is accepted by the network node. The method may also include transmitting the measurement configuration for the apparatus and the measurement configuration for the network node to a user equipment.
