Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple antenna panels are used for simultaneous communication over multiple directional beams, then system performance and signal-to-noise ratio are improved, but device complexity and configuration difficulty increase

Engineering Contradiction:
Improvesystem performanceVSAvoidconfiguration complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the antenna system into multiple independent antenna panels, where each panel can be individually configured and activated. The network can dynamically select and activate specific panels based on communication needs, rather than treating the entire antenna system as a single complex unit. This segmentation allows for simplified configuration of individual panels while achieving improved system performance through multi-panel operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic panel activation and deactivation based on real-time communication conditions. The network can dynamically switch between single-panel and multi-panel configurations, and between different directional beams, depending on signal quality, interference levels, and data rate requirements. This dynamic adaptability allows the system to optimize performance while maintaining manageable configuration complexity.

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If unified TCI framework is implemented for multi-panel configuration, then ease of operation is improved, but adaptability to different configuration scenarios may be limited

Engineering Contradiction:
Improveconfiguration easeVSAvoidconfiguration flexibility
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The unified TCI framework serves multiple functions: it can indicate TCI states for single-panel configurations, multi-panel configurations, different directional beams, and various transmission points. By designing the TCI mechanism to be universally applicable across different scenarios, the patent simplifies the overall configuration process while maintaining the ability to adapt to specific requirements through the content of TCI state indications.

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

Solution Approach 2:

The patent utilizes parameter changes within the TCI states to adapt to different configuration scenarios. By varying the parameters indicated in TCI states (such as beam directions, panel identifiers, transmission point associations), the unified framework can accommodate diverse communication scenarios without requiring separate configuration mechanisms, thus maintaining both ease of operation and adaptability.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If dynamic panel switching is enabled, then productivity and resource allocation efficiency are improved, but loss of time for configuration switching may occur

Engineering Contradiction:
Improveresource allocation efficiencyVSAvoidconfiguration switching time
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent employs preliminary configuration where multiple TCI states are pre-configured and stored in the UE before actual communication begins. When dynamic panel switching is needed, the network can quickly activate a pre-configured TCI state rather than performing configuration procedures in real-time. This preliminary preparation significantly reduces the time loss associated with configuration switching while maintaining high resource allocation efficiency.

Inventive Principle:
Principle #10Preliminary action

AI summary

Devices and methods for wireless communication between a scheduled entity having a plurality of antenna elements operable as multiple antenna and a scheduling entity include signaling transmission configuration information (TCI) to a scheduled entity to define unified TCI states that indicate beam directions of multiple corresponding beams, signaling a unified TCI state to be used for an upcoming communication for the scheduled entity using two or more beams as indicated by the unified TCI state.
