Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If separate processes are used for beam and channel state information measurements, then measurement accuracy can be maintained, but latency and overhead increase
Solution Approach 1:
The patent combines beam measurements and channel state information measurements into a single simultaneous process using the same reference signals. The wireless device performs both measurements concurrently based on beam management reference signals, eliminating the need for separate measurement processes and reducing latency while maintaining measurement accuracy through integrated processing.
2Measurement precision
If separate processes are used for beam and channel state information measurements, then measurement completeness is ensured, but overhead increases
Solution Approach 1:
The patent merges beam measurements and channel state information measurements into a single process that uses the same beam management reference signals. This integration reduces the overhead associated with separate measurement processes while ensuring measurement completeness through comprehensive reporting of both beam and channel state information in a unified measurement framework.
Solution Approach 2:
The beam management reference signals serve multiple functions simultaneously: they enable both beam measurements and channel state information measurements. This multi-functionality reduces the overall system overhead by eliminating the need for separate reference signals and processing procedures for each measurement type.
3Measurement precision
If sequential measurement processes are used, then measurement accuracy is maintained, but productivity decreases
Solution Approach 1:
The patent enables continuous and simultaneous performance of both beam measurements and channel state information measurements without interruption or sequential processing. This continuous measurement approach improves productivity by eliminating idle time between measurements while maintaining accuracy through comprehensive measurement reporting for both beam and channel state information.
