Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If beam refinement operations are performed using dedicated resources, then beam management precision is improved, but resource utilization efficiency deteriorates
Solution Approach 1:
The patent applies multi-functionality by enabling uplink resources to serve dual purposes: primary data transmission and secondary beam refinement operations. The network device configures uplink resources that can be dynamically used for both communication data and beam management, eliminating the need for separate dedicated beam refinement resources and thereby improving resource utilization efficiency while maintaining beam management precision.
2Reliability
If excess resources are allocated for beam refinement, then beam alignment robustness is improved, but system complexity increases
Solution Approach 1:
The patent implements self-service by enabling the network device to autonomously determine excess uplink resources and automatically configure them for beam refinement operations. The system self-manages the resource allocation, beam sweeping configuration, and refinement process without requiring complex coordination protocols or additional terminal device functionality, thereby improving beam alignment robustness while avoiding system complexity increase.
3Productivity
If under-utilized resources are leveraged for beam refinement, then resource efficiency is improved, but beam management complexity increases
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the configuration of uplink resources based on network conditions and beam refinement requirements. The network device monitors resource utilization metrics and modifies resource allocation parameters, bandwidth parts, and beam sweeping configurations to efficiently utilize under-utilized resources for beam refinement, achieving improved resource efficiency through controlled parameter adjustments rather than complex structural changes.
