Uplink Control Resource Segmentation for Priority-Aware Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communications networks face challenges in efficiently handling multicast or broadcast transmissions, particularly in managing acknowledgement information with varying priorities and resource allocations, leading to potential delays or loss of control information.
Innovation Solution
A method for independently encoding and transmitting control information with different priorities using separate subsets of uplink communication resources, allowing for efficient multiplexing without compromising reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If control information with different priorities is transmitted using shared uplink resources, then resource utilization is improved, but reliability of high-priority control information deteriorates due to potential collisions and multiplexing conflicts
Solution Approach 1:
The patent segments uplink communication resources into multiple distinct sets, where each set is dedicated to transmitting control information of a specific priority level. This segmentation prevents collisions between different priority control information while maintaining high resource utilization by fully utilizing each dedicated resource set for its intended purpose without multiplexing conflicts.
2Productivity
If control information is transmitted using multiplexing techniques, then resource efficiency is improved, but complexity of resource management increases
Solution Approach 1:
The patent divides uplink resources into separate dedicated sets for different priority levels, eliminating the need for complex multiplexing management. Each priority level has its own resource set, simplifying the resource management process while maintaining high efficiency through parallel transmission capabilities.
Solution Approach 2:
The patent applies different resource allocation strategies to different priority levels, with high-priority control information receiving dedicated protected resources while lower-priority information utilizes other resource sets. This local differentiation optimizes resource efficiency for each priority level without requiring complex global multiplexing management.
3Reliability
If acknowledgement information is transmitted with high reliability, then transmission accuracy is improved, but transmission time increases due to additional redundancy and confirmation protocols
Solution Approach 1:
The patent segments uplink resources into dedicated sets for different priority levels, allowing high-priority acknowledgement information to be transmitted immediately on dedicated resources without waiting for multiplexing opportunities or additional confirmation protocols. This segmentation ensures high transmission accuracy while minimizing transmission time by eliminating unnecessary delays.
