VSEngineering Contradiction Analysis

1Reliability

If multiple beams are designed for high frequency communication to ensure coverage, then coverage quality is improved, but system overhead increases

Engineering Contradiction:

Improvecoverage qualityVSAvoidsystem overhead

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The query beam set is divided into multiple query beam groups, where each group contains multiple query beams. This segmentation allows the system to train multiple beams simultaneously by transmitting pilot information for multiple query beams within a single beam training period, thereby reducing the number of sequential training operations needed while maintaining comprehensive beam coverage.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a grouping dimension to organize query beams, creating a hierarchical structure where beams are arranged in groups. This dimensional organization enables parallel processing of multiple beams within each group during the beam training phase, reducing the overall training time and system overhead while ensuring adequate coverage.

Inventive Principle:
