Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If circular or elliptical radio cell coverage is used, then the coverage area is simple to define and implement, but the coverage does not efficiently match uneven population density and communication service demand
Solution Approach 1:
The patent applies dynamics by enabling the radio cell coverage shape to be dynamically configured based on actual communication needs and population density distributions. Instead of fixed circular or elliptical shapes, the system can adapt the coverage area geometry in real-time to match geographical requirements, thereby improving adaptability while managing complexity through programmable control of antenna entities.
Solution Approach 2:
The patent implements local quality by allowing different regions to have different coverage characteristics. The antenna entity can be configured to provide non-uniform coverage shapes that match local population density and communication demands, so that densely populated areas receive optimized coverage compared to sparsely populated regions, thereby improving overall system adaptability.
2Area of stationary object
If multiple non-terrestrial network components are deployed to cover extended geographical areas, then comprehensive coverage is achieved, but the system complexity and cost increase
Solution Approach 1:
The patent applies merging by combining the functions of multiple non-terrestrial network components into a single integrated antenna entity that can provide extended geographical coverage. The antenna entity is configured to serve multiple radio cells simultaneously, reducing the number of separate components needed while maintaining comprehensive coverage of extended geographical areas.
Solution Approach 2:
The patent implements universality by designing the antenna entity to perform multiple functions: it can serve multiple radio cells, adapt to different coverage shapes, and operate across various communication scenarios. This multi-functional capability reduces the need for dedicated components for each function, thereby reducing overall system complexity while maintaining extensive coverage capability.
3Reliability
If resources are distributed uniformly across the coverage area, then all areas receive equal service, but communication performance is not optimized for densely populated areas
Solution Approach 1:
The patent applies local quality by enabling differentiated resource allocation based on local communication demands. The antenna entity can be configured to provide enhanced coverage and performance in densely populated areas while maintaining appropriate service levels in sparsely populated regions. This localized optimization improves overall communication performance reliability without requiring complete redesign of the entire coverage area.
Solution Approach 2:
The patent implements parameter changes by allowing dynamic adjustment of coverage shape and characteristics based on population density and communication demand. The system can modify parameters such as coverage area boundaries, signal strength distribution, and resource allocation patterns to optimize performance in densely populated areas while maintaining adaptability across different geographical regions.

AI summary
A method for enabling communication between a user equipment and a mobile communication network includes: operating an antenna entity or functionality or configuring the antenna entity or functionality such that the shape of a coverage area of a radio cell is configured or configurable in a predefined manner other than circular or elliptical. The mobile communication network is or at least comprises a part corresponding to or being a non-terrestrial network. The user equipment is served by a base station entity which is part of that non-terrestrial network or that non-terrestrial network part. The base station entity has or is provided with—in view of serving or providing radio coverage to the user equipment—at least the antenna entity or functionality.
