Full Duplexing Mode Configuration for Uplink-Downlink Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In current 4G and 5G mobile communication systems, the full duplexing mode is limited by device performance, leading to bottlenecks in uplink-downlink isolation, which hinders efficient frequency resource utilization and increases service delay.
Innovation Solution
User Equipment (UE) sends information to a network device to configure a full duplexing mode, allowing the network device to determine the appropriate working mode based on transmission power and mobility state, thereby enabling improved frequency resource utilization and reduced service delay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If full duplexing mode is implemented, then frequency resource utilization rate is improved, but device complexity increases
Solution Approach 1:
The patent changes the operational parameters of the device by introducing full duplexing mode, which allows simultaneous uplink and downlink transmissions on the same frequency resource. This parameter change enables the system to improve frequency resource utilization rate without requiring fundamentally different device architecture, thereby addressing the contradiction between productivity improvement and device complexity.
2Loss of time
If full duplexing mode is implemented, then service delay is reduced, but uplink-downlink isolation becomes more difficult
Solution Approach 1:
The patent introduces self-interference cancellation mechanisms as an intermediary component that mediates between uplink and downlink transmissions. This intermediary actively cancels out the interference caused by simultaneous transmissions, enabling full duplexing mode to operate effectively while maintaining adequate uplink-downlink isolation, thus reducing service delay without being hindered by interference issues.
3Reliability
If traditional duplexing modes are used, then uplink-downlink isolation is maintained, but frequency resource utilization rate is limited
Solution Approach 1:
The patent transitions from static duplexing modes (TDD or FDD) to a dynamic full duplexing mode where the system can adaptively manage uplink and downlink transmissions simultaneously on the same frequency resource. This dynamic approach allows the system to maintain reliable uplink-downlink isolation through active interference management while significantly improving frequency resource utilization rate, resolving the contradiction between reliability and productivity.
