Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If interference detection and circumvention techniques are used between different wireless communication systems, then interference between systems is reduced, but spectrum utilization rate decreases
Solution Approach 1:
The patent implements dynamic frequency band scheduling by continuously monitoring interference levels between NR and LTE systems and adjusting the available frequency bands in real-time. The network device dynamically determines which frequency bands are suitable for NR based on current interference conditions, transitioning from static to dynamic resource allocation to resolve the contradiction between interference avoidance and spectrum utilization.
Solution Approach 2:
The patent changes the parameter of frequency band availability by adjusting the set of usable frequency bands based on interference measurement results. The network device modifies the frequency band configuration dynamically according to interference levels, allowing the system to adapt parameters (frequency band selection) to changing conditions rather than maintaining fixed parameters.
2Reliability
If traditional interference detection techniques are used, then interference between systems is detected, but real-time interference strength determination is not achieved
Solution Approach 1:
The patent implements a feedback mechanism where terminal devices measure interference levels in frequency bands and report this information back to the network device. The network device uses this feedback to continuously update its understanding of interference conditions and adjust frequency band allocations accordingly, achieving real-time interference strength determination through closed-loop feedback.
Solution Approach 2:
The patent enables terminal devices to perform self-measurement of interference levels in their received frequency bands and report results autonomously. The terminal devices serve themselves by conducting measurements and providing interference information without requiring complex network-side measurement infrastructure, enabling distributed interference detection.
