Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If beam measurements are performed across multiple frequency bands, then beam management accuracy is improved, but device power consumption increases
Solution Approach 1:
The patent applies universality by using beam correspondence information from a first frequency band to manage beams in a second frequency band. The beam management mechanism becomes multi-functional, serving both frequency bands through shared beam information, thereby avoiding redundant measurements in the second band while maintaining accurate beam management across both bands.
Solution Approach 2:
The patent implements preliminary action by performing beam measurements and establishing beam correspondence information in the first frequency band before needing to manage beams in the second frequency band. This pre-established beam information is then reused for the second band, eliminating the need for separate measurements and reducing overall power consumption.
2Measurement precision
If extensive beam measurements are conducted across multiple bands, then beam indication accuracy is improved, but resource usage increases
Solution Approach 1:
The patent makes the beam measurement process multi-functional by using measurements from the first frequency band to serve both the first and second frequency bands. The beam correspondence information acts as a universal resource that provides accurate beam indication for multiple bands without requiring separate measurement campaigns for each band, thereby reducing overall resource consumption.
Solution Approach 2:
The patent applies copying by replicating beam correspondence information from the first frequency band to the second frequency band. Instead of performing original measurements in the second band, the system copies the beam information relationship established in the first band, maintaining accuracy while significantly reducing the resources needed for beam management.
3Measurement precision
If separate beam management is implemented for each frequency band, then beam management precision is improved, but device complexity increases
Solution Approach 1:
The patent merges the beam management processes of the first and second frequency bands by establishing beam correspondence between them. Instead of maintaining completely separate beam management systems for each band, the patent combines them through shared beam information, reducing the overall complexity of the beam management architecture while preserving the precision needed for accurate beam indication.
Solution Approach 2:
The patent creates a universal beam management approach where a single beam correspondence framework serves multiple frequency bands. This multi-functional system eliminates the need for separate independent management mechanisms for each band, thereby reducing device complexity while maintaining the precision required for accurate beam management across different bands.
