Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
TDD systems face limitations in uplink transmission rate and latency due to the imbalance in the configuration of DL and UL slots, leading to suboptimal resource utilization and network performance.
Innovation Solution
Implementing a Sub-Band Full Duplex (SBFD) time-frequency resource configuration to enable simultaneous uplink and downlink data transmission, allowing flexible use of frequency-domain resources for both directions, thereby optimizing resource utilization and improving network capacity and coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a terminal sends data to multiple anchor nodes for positioning, then positioning accuracy is improved, but data transmission overhead and network load increase
Solution Approach 1:
The patent segments the positioning data transmission process by dividing data into first data (sent to multiple anchor nodes for positioning) and second data (sent to a specific anchor node for non-positioning purposes). This segmentation allows the system to optimize transmission routes for different data types, reducing overall overhead while maintaining positioning accuracy through multi-node reception of the first data.
Solution Approach 2:
The patent introduces a network controller as an intermediary that manages and coordinates data transmission between terminals and anchor nodes. The network controller receives data from terminals, determines appropriate transmission routes, and forwards data to suitable anchor nodes, thereby optimizing network resource utilization and reducing unnecessary transmission overhead.
2Reliability
If data is transmitted to multiple anchor nodes, then positioning reliability is improved, but network resource consumption increases
Solution Approach 1:
The patent applies local quality by assigning different transmission qualities to different data types. First data intended for positioning is transmitted to multiple anchor nodes with high reliability requirements, while second data for non-positioning purposes is transmitted to a single designated anchor node with lower resource consumption, thereby optimizing the balance between reliability and energy usage.
Solution Approach 2:
The patent implements partial action by sending positioning data to multiple anchor nodes only when positioning is required, rather than continuously transmitting to all anchor nodes. The network controller intelligently determines when multi-node transmission is necessary, reducing unnecessary network resource consumption while maintaining positioning reliability when needed.
3Adaptability or versatility
If the system supports both positioning and non-positioning data transmission, then system versatility is improved, but device complexity increases
Solution Approach 1:
The patent implements universality by designing a unified data transmission framework that handles both positioning and non-positioning data through the same network controller and anchor node infrastructure. The system can adaptively switch between different transmission modes based on data type, providing multi-functionality without requiring separate dedicated systems for each purpose.
Solution Approach 2:
The patent applies dynamics by making the data transmission route configurable and adaptable based on the specific requirements of the data being transmitted. The network controller dynamically determines whether to route data to multiple anchor nodes or a single anchor node based on real-time conditions and data type, reducing the need for complex static configuration while maintaining versatility.
