Engineering Contradiction Analysis
1Productivity
If multiple reference signals are transmitted in the same slot using different transmission spatial settings, then beam management efficiency is improved, but transmission reliability deteriorates due to potential interference and conflict
Solution Approach 1:
The patent divides the slot into multiple subsets, where each subset contains reference signals with the same transmission spatial setting. This segmentation allows multiple reference signals to be transmitted in the same slot without interference, as signals in different subsets use different spatial settings. The first reference signal uses a first spatial setting while the second reference signal uses a second spatial setting, enabling efficient beam management while maintaining transmission reliability through structured organization.
2Area of stationary object
If reference signals are transmitted using multiple transmission spatial settings, then spatial coverage is improved, but signal interference increases
Solution Approach 1:
The patent segments reference signals into multiple subsets based on their transmission spatial settings. Each subset contains only reference signals with identical spatial settings, which eliminates interference between different spatial settings. This allows the system to cover multiple spatial directions simultaneously while preventing signal interference through careful organization of signals within subsets.
Solution Approach 2:
The patent introduces a subset structure as an intermediary organization layer between the reference signals and the transmission spatial settings. This intermediary structure mediates the relationship by grouping signals that can coexist without interference, allowing multiple spatial settings to operate simultaneously while managing the harmful effect of potential interference through structured separation.
3Adaptability or versatility
If a set of slots with multiple transmission spatial settings is configured, then beam management capability is improved, but system complexity increases
Solution Approach 1:
The patent segments the configuration into a clear structure where a set of slots is divided into multiple subsets, each subset corresponding to a specific transmission spatial setting. This segmentation makes the complex beam management capability more manageable and easier to implement, as the system can process and manage each subset independently while maintaining the overall beam management capability across multiple slots and spatial settings.
