PUCCH PUSCH Overlapping Transmission Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in 5G NR, face challenges in efficiently managing overlapping uplink transmissions where uplink control information and data overlap in the time domain, leading to inefficiencies in resource allocation and transmission modes.
Innovation Solution
The implementation of a method where user equipment (UE) receives an overlapping uplink transmission configuration from a base station, allowing it to detect and manage overlapping uplink transmissions by applying configured modes such as multiplexing, priority-based, or simultaneous transmission based on capabilities and priorities, optimizing resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If uplink control information and uplink data are transmitted simultaneously in overlapping time resources, then resource utilization and communication efficiency are improved, but transmission conflicts and interference between control and data channels increase
Solution Approach 1:
The patent implements dynamic selection between simultaneous transmission and multiplexing modes based on real-time detection of overlapping uplink transmissions. The system transitions from static resource allocation to dynamic mode selection, adapting the transmission strategy according to the detected overlap conditions between PUCCH and PUSCH resources.
Solution Approach 2:
The patent changes the transmission parameter by selecting different modes (simultaneous transmission vs. multiplexing) based on the overlapping configuration detection. This parameter change allows the system to optimize between throughput and reliability by adjusting the transmission approach according to the specific overlap scenario detected.
2Adaptability or versatility
If the system supports both simultaneous transmission and multiplexing modes for overlapping uplink transmissions, then adaptability and versatility are improved, but device complexity and configuration management increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring the UE with overlapping uplink transmission modes through RRC signaling before actual transmissions occur. The base station provides advance configuration including simultaneous transmission mode and multiplexing mode parameters, so the UE is prepared with multiple transmission strategies ready for selection based on detected conditions.
Solution Approach 2:
The patent implements feedback through the detection mechanism that monitors overlapping uplink transmission conditions and uses this information to select the appropriate transmission mode. The system continuously feedbacks on the overlap detection results and adjusts the transmission mode accordingly, creating a closed-loop control system that manages complexity through intelligent decision-making.
