Engineering Contradiction Analysis
1Productivity
If mobile relay nodes are deployed without location and direction information, then deployment flexibility and speed are improved, but network coverage optimization deteriorates and interference with existing infrastructure increases
Solution Approach 1:
The patent applies preliminary action by having the mobile relay node determine its location and direction information before actual network operation begins. The node requests and receives configuration parameters (including location-dependent settings) from the infrastructure node during the setup phase, ensuring optimal coverage and interference avoidance is established prior to deployment. This pre-configuration approach enables fast deployment while preventing harmful interference from the outset.
Solution Approach 2:
The patent implements feedback mechanisms where the mobile relay node continuously reports its location and operational status to the infrastructure node. The infrastructure node uses this feedback to dynamically adjust configuration parameters, beamforming settings, and resource allocation. This closed-loop feedback system allows the network to adapt to changing conditions, optimizing coverage while minimizing interference with existing infrastructure in real-time.
2Device complexity
If mobile relay nodes operate without location-dependent configuration parameters, then device complexity is reduced, but network coverage optimization deteriorates
Solution Approach 1:
The patent introduces an intermediary infrastructure node that acts as a mediator between the mobile relay node and the network core. This infrastructure node handles the complex tasks of determining location, calculating optimal configuration parameters, and managing beamforming settings. By offloading these complex functions to the infrastructure node, the mobile relay node itself remains relatively simple while still achieving optimized network coverage through the intermediary's assistance.
3Ease of operation
If mobile relay nodes use static configuration parameters, then ease of operation is improved, but adaptability to different locations deteriorates
Solution Approach 1:
The patent implements dynamics by transitioning from static configuration parameters to dynamic, location-dependent parameters. The mobile relay node continuously updates its location information and receives adjusted configuration parameters from the infrastructure node based on current position, direction, and environmental conditions. This dynamic adaptation enables the system to maintain operational simplicity through automated parameter adjustment while achieving high location versatility and coverage optimization.
