Solution Overview
Problem
Existing technologies for improving transmission reliability in wireless communication systems, such as Multi-TRP and Multi-Panel systems, face resource occupancy issues due to repetitive transmission methods.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If repetitive transmission is performed N times to improve transmission reliability, then the reliability of physical channel transmission is improved, but the resource occupancy increases N times
Solution Approach 1:
The patent divides the N repetitive transmissions into K groups, where each group uses a separate reference signal parameter copy. This segmentation allows the system to manage reference signal resources more efficiently by grouping transmissions rather than treating each transmission individually, thereby reducing overall resource occupancy while maintaining reliability.
Solution Approach 2:
The patent changes the parameter configuration by introducing K copies of reference signal parameters instead of using the same parameters for all N transmissions. This parameter variation enables different transmission groups to use optimized reference signal configurations, improving resource utilization efficiency while maintaining the required transmission reliability.
2Productivity
If K copies of reference signal parameters are used for N repetitive transmissions, then the resource utilization efficiency is improved, but the system complexity increases
Solution Approach 1:
The patent creates K copies of reference signal parameters that can serve multiple transmission groups. Each parameter copy is universal and can be applied to multiple transmissions within its group, allowing the system to handle N repetitive transmissions with only K parameter sets. This multi-functionality approach improves resource utilization without proportionally increasing system complexity.
