Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If signaling protocols are used to indicate beam selection information, then beam selection capability is improved, but signaling overhead and complexity increase

Engineering Contradiction:

Improvebeam selection reliabilityVSAvoidsignaling protocol complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The wireless device autonomously selects beams and activates antenna panels based on its own measurements and criteria, without requiring complex signaling protocols from the base station to dictate beam selection. The device serves itself in making beam selection decisions, reducing signaling overhead while maintaining reliability through autonomous intelligence

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent extracts the beam selection decision-making function from the signaling protocol and transfers it to the wireless device itself. By taking out the complex signaling requirements and replacing them with autonomous device behavior, the system reduces signaling overhead while preserving beam selection capability

Inventive Principle:

Principle #2Taking out (Extraction)

2Productivity

If multiple antenna panels are activated for diverse beam selection, then data transfer efficiency is improved, but device complexity and power consumption increase

Engineering Contradiction:

Improvedata transfer efficiencyVSAvoidantenna panel management complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The wireless device dynamically activates or deactivates antenna panels based on real-time communication conditions and data transfer requirements. This dynamic adjustment allows the system to use multiple panels when needed for high efficiency while reducing to fewer panels when conditions permit, optimizing the balance between productivity and complexity

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes the operational parameters of antenna panels (activation state, beam direction, transmission power) based on communication needs. By adjusting these parameters dynamically, the system achieves high data transfer efficiency when multiple panels are active while allowing simplification when fewer panels suffice

Inventive Principle:

Principle #35Parameter changes

3Loss of time

If autonomous antenna panel activation is implemented, then latency is reduced, but control accuracy and coordination difficulty increase

Engineering Contradiction:

Improveactivation latencyVSAvoidbase station coordination reliability

Core Design Contradiction:

Loss of timeVSReliability

Solution Approach 1:

The wireless device performs preliminary autonomous activation of antenna panels when urgent data transfer is detected, acting before the base station can respond. This preliminary action reduces latency by eliminating waiting time for base station commands, while subsequent reporting ensures coordination reliability is maintained

Inventive Principle:

Principle #10Preliminary action

4Measurement precision

If beam selection signaling information is provided by base station, then beam selection accuracy is improved, but signaling overhead increases

Engineering Contradiction:

Improvebeam selection accuracyVSAvoidsignaling overhead

Core Design Contradiction:

Measurement precisionVSLoss of information

Solution Approach 1:

Instead of the base station providing beam selection information to the wireless device (traditional approach), the patent inverts the direction by having the wireless device autonomously determine beam selection and report only the outcome to the base station. This inversion eliminates extensive signaling overhead while maintaining selection accuracy through device-side intelligence

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

Wireless communications are described. A wireless device may comprise various hardware and/or software transmission/reception components (e.g., one or more antenna panels, transceivers, encoders, decoders, validators). The wireless device may selectively activate or deactivate transmission/reception components for reception of data from one or more cells and/or transmission points. The wireless device may report the activation status of the transmission/reception components to a base station via reports and/or messages. The base station may schedule future transmissions and/or send future messages via selected transmission/reception components, for example, based on the activation status indicated by the wireless device.
