Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple beamforming codebooks are supported for antenna arrays in disaggregated network nodes, then communication efficiency and signal quality are improved, but device complexity and configuration management difficulty increase

Engineering Contradiction:

Improvesignal qualityVSAvoidcodebook management complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the beamforming codebook configuration into separate capability signaling and configuration signaling phases. The radio unit first signals its codebook support capability, then the distributed unit provides specific codebook configurations. This segmentation reduces management complexity by separating capability declaration from active configuration.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces capability information as an intermediary element between the radio unit and distributed unit. This capability information acts as a mediator that enables the distributed unit to understand and properly configure multiple beamforming codebooks, simplifying the overall management process.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If capability information signaling is implemented for beamforming codebooks, then adaptability and configuration flexibility are improved, but loss of time and signaling overhead increase

Engineering Contradiction:

Improvecodebook configuration flexibilityVSAvoidsignaling time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent implements preliminary capability information signaling during the setup phase, where the radio unit announces its beamforming codebook support capabilities in advance. This preliminary action allows the distributed unit to prepare appropriate configurations without requiring repeated real-time capability queries, reducing overall signaling time.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The radio unit autonomously signals its own capability information without requiring external configuration or probing. This self-service approach reduces signaling overhead and time by eliminating the need for the distributed unit to discover or verify codebook capabilities through additional signaling exchanges.

Inventive Principle:

Principle #25Self-service
