PUSCH Selection Rules for Overlapped Uplink Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current protocols fail to clarify how user equipment determines which physical uplink shared channels (PUSCH) to transmit, leading to poor transmission performance.
Innovation Solution
User equipment determines N PUSCHs for transmission based on parameter information such as resource set information, number of transmission layers, and priority, using selection rules to select PUSCHs with highest priority or maximizing the number of layers within transmission capability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If user equipment has multiple PUSCHs for transmission, then transmission capacity is improved, but it becomes unclear which PUSCHs to transmit actually, resulting in poor transmission performance
Solution Approach 1:
The patent introduces parameter changes by modifying the selection criteria for PUSCH transmission. The network side modifies scheduling parameters and the user equipment modifies selection parameters based on priority information, resource set information, and transmission capability parameters to determine which PUSCHs to transmit actually, resolving the ambiguity while maintaining high transmission capacity
Solution Approach 2:
The patent implements feedback mechanisms where the user equipment reports transmission capability information and the network side provides scheduling information with priority indicators. This feedback loop enables dynamic determination of which PUSCHs to transmit, ensuring reliable transmission performance while utilizing multiple PUSCHs for high capacity
2Productivity
If user equipment transmits multiple PUSCHs simultaneously, then transmission efficiency is improved, but transmission capability constraints may be violated
Solution Approach 1:
The patent applies dynamics by making the transmission configuration adjustable and adaptive. The user equipment dynamically determines which PUSCHs to transmit based on real-time capability information and scheduling parameters, allowing the system to adapt between high efficiency and capability constraints as needed
Solution Approach 2:
The patent implements partial action by selecting only the necessary number of PUSCHs for transmission based on capability constraints. Instead of always transmitting all possible PUSCHs, the system transmits only the required number (N PUSCHs) that fits within transmission capability while maximizing efficiency
3Reliability
If user equipment selects PUSCHs based on priority, then high-priority transmission is ensured, but lower-priority PUSCHs may be excluded
Solution Approach 1:
The patent applies segmentation by dividing PUSCHs into different priority groups and resource sets. The selection process segments the transmission decision into multiple stages: first selecting high-priority PUSCHs, then selectively adding lower-priority PUSCHs from different resource sets, ensuring both priority guarantee and overall transmission volume
