Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If pre-determined communication parameters are used for a given radio operating environment, then the system is simple to operate, but performance becomes non-optimal when the radio operating environment varies

Engineering Contradiction:

Improvesystem operation simplicityVSAvoidcommunication performance

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent implements dynamic waveform parameter adaptation by allowing the system to switch between different parameter sets (e.g., first waveform parameters for mobile receivers, second waveform parameters for fixed receivers) based on the detected radio operating environment. This dynamic adjustment resolves the contradiction by maintaining operational simplicity through automated environment detection while achieving optimal performance through adaptive parameter selection.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes physical or system parameters (waveform parameters such as subcarrier spacing, cyclic prefix length, FFT size) to optimize performance for different radio operating environments. By modifying these parameters based on environment type (mobile vs. fixed, urban vs. rural), the system achieves optimal communication performance without complicating user operation.

Inventive Principle:

Principle #35Parameter changes

2Reliability

If waveform parameters are optimized for one radio operating environment, then performance is optimal for that environment, but performance deteriorates in different environments

Engineering Contradiction:

Improvecommunication performance in target environmentVSAvoidperformance across varying environments

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent creates a universal communication system that can function optimally in multiple different radio operating environments by incorporating multiple waveform parameter sets. The system detects the current environment and selects the appropriate parameter set, enabling a single system to serve mobile receivers, fixed receivers, urban areas, and rural areas with optimal performance in each scenario.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system dynamically adapts waveform parameters based on real-time environment detection. Rather than being fixed for one environment, the system transitions between different parameter configurations (e.g., adjusting subcarrier spacing for mobile vs. fixed receivers), thereby achieving both environmental optimization and cross-environment adaptability.

Inventive Principle:

Principle #15Dynamics

3Device complexity

If a single set of communication parameters is used for all environments, then device complexity is reduced, but adaptability to different radio operating environments deteriorates

Engineering Contradiction:

Improveparameter configuration complexityVSAvoidenvironmental adaptability

Core Design Contradiction:

Device complexityVSAdaptability or versatility

Solution Approach 1:

The system performs self-service by automatically detecting the radio operating environment and selecting the appropriate waveform parameter set without requiring manual configuration. The environment detection mechanism and parameter selection logic are integrated into the system, allowing it to adapt autonomously to different conditions (mobile/fixed receivers, urban/rural settings) while keeping the user interface simple.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent pre-configures multiple waveform parameter sets corresponding to different radio operating environments before actual communication begins. The system includes pre-defined parameter configurations (first waveform parameters for mobile, second for fixed) that are selected based on environment detection, eliminating the need for complex real-time calculations while maintaining high adaptability.

AI summary

Techniques for operating a wireless network in a plurality of radio operating environments are disclosed. In some embodiments, an apparatus receives a first parameter value set that is selected from a group of multiple parameter value sets, wherein the first parameter value set is appropriate for a first target radio operating environment that corresponds to one or more of: a first level of mobility of user devices or a first range of wireless transmission. In some embodiments, the apparatus is reconfigured to receive wireless broadcast transmissions from a second broadcast transmitter using a second parameter value set that is appropriate for a second target radio operating environment. The first and second broadcast transmitters may be the same or different. The parameter value sets may include a first parameter based upon which the apparatus is configured to determine subcarrier spacing and a second parameter that indicates a cyclic prefix size.
