Dual Connectivity Band Selection Using MN-SN Throughput Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing MR-DC CA configurations do not maximize throughput due to insufficient coordination between the master and secondary nodes, leading to suboptimal selection of band combinations and feature sets, which affects network efficiency.
Innovation Solution
Implement a method for MR-DC CA configuration that includes signaling additional information about achievable throughput and feature sets between the master and secondary nodes to optimize band combination selection, allowing for a more efficient network operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If MR-DC CA configuration is performed with traditional MN or SN preferred methods, then the configuration process is simple, but the total throughput is not maximized
Solution Approach 1:
The patent implements a feedback mechanism where the secondary node evaluates the configured band combination and feature set, then provides feedback to the master node about whether the configuration achieves optimal throughput. Based on this feedback, the master node can adjust the configuration to maximize total MR-DC throughput while maintaining manageable complexity through iterative optimization.
2Productivity
If additional coordination information is signaled between MN and SN, then band combination selection is optimized, but signaling overhead increases
Solution Approach 1:
The patent extracts only the essential coordination information needed for optimization - specifically the secondary node's evaluation of whether the current band combination and feature set configuration achieves optimal throughput. By taking out only this critical feedback rather than exchanging all possible configuration parameters, the patent reduces signaling overhead while maintaining selection efficiency.
3Adaptability or versatility
If MR-DC is configured with multiple band combinations and feature sets, then adaptability to different scenarios is improved, but configuration complexity increases
Solution Approach 1:
The patent implements dynamic configuration where the master node and secondary node can adjust band combinations and feature sets based on current network conditions and throughput requirements. Rather than statically configuring all possible combinations, the system dynamically selects and adjusts configurations, maintaining high adaptability to different scenarios while reducing complexity through on-demand configuration.
