Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple first beams are co-phased to form wider second beams, then coverage area is improved, but beam measurement precision deteriorates
Solution Approach 1:
The beam management process is segmented into two distinct phases: measurement phase using narrow first beams for high precision, and coverage phase using wider second beams formed by co-phasing. This segmentation allows each phase to optimize for its specific requirement without compromising the other.
Solution Approach 2:
The system dynamically switches between using narrow first beams for measurement and wider second beams for coverage based on mobility detection criteria. The beam configuration is not static but adapts to changing channel conditions and mobility states, optimizing both precision and coverage at different times.
2Adaptability or versatility
If beam configurations are adapted for high mobility scenarios, then adaptability is improved, but system complexity increases
Solution Approach 1:
The system performs preliminary beam measurements using narrow first beams to establish baseline channel characteristics before switching to wider second beams for coverage. This preliminary action provides the necessary information to adapt to mobility conditions without requiring complex real-time processing during high mobility states.
Solution Approach 2:
The system implements feedback mechanisms where measurement results from first beams inform the configuration of second beams. The network entity receives measurement reports and adjusts beam configurations accordingly, creating a closed-loop system that adapts to mobility conditions through feedback-driven optimization.
3Measurement precision
If narrow first beams are used for measurements, then measurement precision is improved, but coverage area deteriorates
Solution Approach 1:
Multiple narrow first beams are merged through co-phasing to form wider second beams. This merging process combines the measurement precision benefits of narrow beams with the coverage benefits of wider beams, achieving both objectives through the combination of multiple beam resources.
Solution Approach 2:
The system adds a temporal dimension to beam management by using narrow beams for initial measurement and then transitioning to wider beams for coverage. This dimensional transition allows the system to achieve both precision and coverage by operating in different temporal phases rather than requiring simultaneous optimization.
4Adaptability or versatility
If co-phasing codebooks are applied to multiple beams, then beam management flexibility is improved, but computational complexity increases
Solution Approach 1:
Co-phasing codebooks are applied selectively to specific groups of beams rather than uniformly to all beams. This local application of codebooks allows the system to maintain flexibility where needed while reducing computational complexity in areas where full codebook processing is not necessary.
Solution Approach 2:
The system applies co-phasing codebooks to a subset of beams (partial action) rather than all beams, or uses pre-computed codebook entries (excessive preparation) to reduce real-time computational requirements. This approach balances flexibility with computational efficiency by not over-processing all beam configurations.

AI summary
An apparatus may be configured with configuration information for beam measurements for a set of first beams, and then receive second configuration information with an indication to co-phase two or more first beams to one or more second beams. Responsive to the indication, the apparatus co-phases. per a second beam, corresponding two or more first beams to the second beam.
