Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing wireless communication protocols are used for non-terrestrial networking, then device compatibility is maintained, but latency increases and reliability decreases
Solution Approach 1:
The patent modifies existing communication protocols by changing key parameters such as measurement reporting intervals, resource allocation patterns, and handover thresholds to optimize performance for non-terrestrial networks, thereby reducing latency and improving reliability without requiring complete protocol redesign
Solution Approach 2:
The patent divides the communication protocol into separate optimization layers, allowing terrestrial and non-terrestrial communication paths to be managed independently with tailored parameters, which reduces overall system latency while maintaining compatibility
2Reliability
If enhanced protocol mechanisms are implemented for non-terrestrial networking, then latency and reliability improve, but device complexity increases
Solution Approach 1:
The patent designs enhanced protocol mechanisms that can operate in both terrestrial and non-terrestrial modes using the same basic framework, allowing devices to handle multiple network types without requiring separate complex protocol stacks, thus improving reliability while limiting complexity growth
Solution Approach 2:
The patent implements pre-configured measurement reporting and resource allocation patterns that are prepared in advance for non-terrestrial scenarios, allowing devices to switch to optimized modes quickly without complex real-time calculations, thereby improving reliability with minimal additional complexity
3Productivity
If measurement reporting is optimized for non-terrestrial networks, then throughput improves, but signaling overhead increases
Solution Approach 1:
The patent implements selective measurement reporting where devices report only the most critical measurement parameters for non-terrestrial networks at optimized intervals, providing sufficient information for throughput optimization while avoiding excessive signaling overhead from complete measurement sets
Solution Approach 2:
The patent combines measurement reporting with existing uplink signaling channels and bundles multiple measurement reports together when possible, reducing the number of separate signaling transmissions and thereby improving throughput without proportionally increasing overhead

AI summary
A system, method and apparatus for wireless communications is provided. A user equipment (UE) receives inter-RAT measurement configuration parameters associated with a first RAT provided by a non-terrestrial node. The inter-RAT measurement configuration parameters include information for detecting one or more events that trigger generating a measurement report. The measurement configuration parameter further include measurement information associated with the first RAT. The UE then determines one or more events based on processing the received inter RAT measurement configuration parameters. The UE generates a measurement report comprising measurement information associated with the first RAT, wherein the measurement report is based on the received inter RAT measurement configuration parameters.
