Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If dynamic beam management and power determination mechanisms are implemented, then signal transmission and reception quality is improved, but device complexity increases

Engineering Contradiction:
Improvesignal transmission and reception qualityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the beam management and power determination functions across multiple TRPs and panels, allowing each component to operate independently with dedicated control mechanisms. This segmentation enables complex signal processing to be distributed rather than centralized, improving reliability while managing complexity through modular architecture.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic beam management where beams can be switched and adjusted in real-time based on channel conditions, and dynamic power determination where transmission power is adaptively controlled per TRP and panel. This dynamic adaptation improves signal quality by optimizing parameters continuously while the system manages complexity through algorithmic control rather than hardware complexity.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If multiple TRPs and panels are supported, then adaptability is improved, but device complexity increases

Engineering Contradiction:
ImproveadaptabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent designs a universal framework that can accommodate multiple TRPs and panels using the same basic architectural elements and control mechanisms. The MAC layer control elements and resource allocation procedures are designed to work across all TRPs and panels, providing multi-functionality that improves adaptability without requiring separate specialized systems for each component.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent manages multiple TRPs and panels by dynamically changing system parameters such as beam directions, power levels, and resource allocations rather than requiring fundamentally different hardware configurations. This parameter-based adaptation allows the system to versatility across multiple TRPs and panels while maintaining a relatively simple underlying hardware architecture.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If beam and power allocation is optimized, then signal transmission efficiency is improved, but loss of energy increases

Engineering Contradiction:
Improvesignal transmission efficiencyVSAvoidloss of energy
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The patent implements feedback mechanisms where channel state information is continuously monitored and used to adjust beam allocations and power levels. This feedback-driven optimization ensures that energy is transmitted efficiently toward the intended receiver by adapting to changing channel conditions, thereby improving transmission efficiency while minimizing energy loss through intelligent resource allocation.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent optimizes signal transmission efficiency by dynamically changing transmission parameters including power levels, beam directions, and modulation schemes based on real-time channel conditions. This adaptive parameter adjustment allows the system to achieve efficient energy utilization by selecting optimal transmission parameters that maximize productivity while minimizing energy waste.

Inventive Principle:

AI summary

A wireless device receives one or more radio resource control (RRC) messages comprising indicating first sets of power (P0) values for physical uplink shared channel (PUSCH) transmissions and second sets of P0 values for PUSCH transmissions. The wireless device receives downlink control information (DCI) scheduling a PUSCH transmission. The wireless device transmits the PUSCH transmission using a transmission power determined based on at least one of a first P0 value in a first set with a lowest index among the first sets and a second P0 value in a second set with the lowest index among the second sets.
