Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single channel resource is used for message transmission, then device complexity is reduced, but communication reliability deteriorates due to channel variations and interference
Solution Approach 1:
The patent segments the transmission resource into multiple PUCCH resources, each associated with different beams or spatial filters. This segmentation allows the system to transmit message repetitions over multiple independent channel resources, thereby improving reliability through spatial diversity while maintaining manageable configuration complexity through standardized resource indication mechanisms.
Solution Approach 2:
The patent introduces spatial dimension diversity by associating different PUCCH resources with different beams or spatial filters. This dimensionality change from single-resource transmission to multi-resource transmission across spatial dimensions enables the system to overcome channel variations and interference, significantly improving communication reliability.
2Reliability
If multiple wireless resources are used for message repetitions, then communication reliability is improved through spatial diversity, but device complexity increases due to resource configuration and management
Solution Approach 1:
The patent creates a universal resource configuration mechanism where a single activation command can indicate multiple PUCCH resources with different beams/spatial filters. This multi-functional approach allows the same resource indication mechanism to handle both single-resource and multi-resource scenarios, improving reliability through spatial diversity while avoiding the need for separate configuration procedures for each resource type.
Solution Approach 2:
The patent utilizes parameter changes in the activation command to dynamically indicate different sets of PUCCH resources. By changing the resource indication parameters based on channel conditions and transmission requirements, the system can adaptively switch between single-resource and multi-resource transmission modes, balancing reliability improvement with complexity management.
