Uplink Control Information Multiplexing on PUCCH
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face challenges in efficiently multiplexing low-priority (LP) and high-priority (HP) uplink control information (UCI) on the same physical uplink control channel (PUCCH), particularly in handling LP HARQ-ACK, HP HARQ-ACK, and HP scheduling request (SR) transmissions, which affects system efficiency and reliability.
Innovation Solution
The method involves transmitting feedback response information of different priorities and SRs over a shared uplink channel resource, where the first priority is higher than the second priority, allowing for the multiplexing of LP HARQ-ACK, HP HARQ-ACK, and HP SR on the same PUCCH, optimizing resource utilization and ensuring reliable high-priority information transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If LP HARQ-ACK, HP HARQ-ACK, and HP SR are multiplexed on the same PUCCH, then resource utilization is improved, but transmission reliability may deteriorate due to priority conflicts
Solution Approach 1:
The patent applies local quality by assigning different priority levels to different UCI types (HP for HP HARQ-ACK and HP SR, LP for LP HARQ-ACK) and implementing priority-based multiplexing rules that treat high-priority and low-priority information differently on the same PUCCH resource, ensuring HP information is transmitted reliably while LP information utilizes remaining capacity
Solution Approach 2:
The patent introduces a priority mechanism as an intermediary that mediates between HP and LP UCI transmissions. The priority rules act as a mediator to determine transmission behavior when HP and LP information coexist on the same PUCCH, resolving conflicts by giving precedence to HP information while allowing LP information to be transmitted when resources are available
2Productivity
If HP SR is transmitted with HP HARQ-ACK on the same PUCCH, then system efficiency is improved, but the complexity of handling priority conflicts increases
Solution Approach 1:
The patent segments the UCI transmission into distinct priority levels (HP and LP) with clearly defined multiplexing rules for each segment. By dividing the transmission handling into priority-based segments, the system manages complexity through structured segmentation rather than treating all UCI uniformly
Solution Approach 2:
The patent implements dynamic priority-based multiplexing rules that adapt transmission behavior based on the presence and type of UCI. The system dynamically adjusts which information is transmitted based on priority levels, enabling flexible handling of HP SR and HP HARQ-ACK combinations without rigid predefined structures
