Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If beam prediction reporting includes detailed measurement information for multiple time points, then prediction accuracy is improved, but reporting overhead and processing complexity increase
Solution Approach 1:
The beam prediction reporting is segmented into multiple time points (first time point and second time point), with each time point containing separate beam measurement information. This segmentation allows the network to process predictions at different granularities and reduces the complexity of handling all measurements uniformly.
Solution Approach 2:
The patent introduces a time dimension to beam reporting by including measurements at multiple time points (first time point and second time point). This transforms the reporting from a single-snapshot view to a temporal sequence, enabling the network to track beam quality changes over time and improve prediction accuracy without overwhelming complexity.
2Reliability
If comprehensive beam information is reported, then transmission reliability is improved, but signaling overhead increases
Solution Approach 1:
The patent extracts and reports only the most critical beam information elements: the first beam information (with highest measurement value) at each time point, along with the time point identifiers. By taking out only the essential elements rather than reporting all beam measurements, the patent maintains reliability while reducing signaling overhead.
Solution Approach 2:
The UE performs preliminary beam measurements and predictions at multiple time points before reporting, organizing the data in advance. This preliminary action allows the network to receive pre-processed, curated beam information that is ready for immediate use in transmission decisions, reducing the need for additional processing and signaling.
3Loss of time
If beam predictions are performed at multiple time points, then latency is reduced, but computational load increases
Solution Approach 1:
The patent implements periodic beam predictions at predetermined time points (first time point and second time point) rather than continuous prediction. This periodic approach reduces computational energy consumption compared to continuous prediction, while still providing timely updates to reduce beam switching latency. The network can configure the periodicity based on channel conditions.
