Wireless Device Multiplexing Control Signaling Overlapping Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern wireless communication systems face challenges in efficiently managing overlapping and large sets of resources for uplink transmission, particularly in prioritizing signaling like URLLC signaling, where existing approaches fail to effectively handle different transmission qualities and latency requirements.
Innovation Solution
A method is disclosed where a wireless device transmits signaling by multiplexing control information onto a common resource structure based on the content and type of information, allowing for efficient use of resources while adhering to latency requirements, by overlapping resource structures associated with different transmission qualities, such as URLLC and eMBB modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple resource structures with different transmission qualities are overlapped to improve resource utilization, then resource efficiency is improved, but resource management complexity increases
Solution Approach 1:
The patent segments resource structures by transmission quality (e.g., first resource structure for high-priority URLLC, second resource structure for low-priority eMBB). This segmentation allows independent management of different resource types while maintaining overall efficiency. The wireless device separately identifies and processes resources based on their associated transmission qualities, reducing the complexity of managing overlapping resources as a unified complex structure.
Solution Approach 2:
Different portions of the resource structure are assigned different transmission qualities and handling rules. High-priority resources (first resource structure) receive preferential treatment in terms of multiplexing decisions and latency handling, while low-priority resources (second resource structure) are managed differently. This local differentiation optimizes resource utilization while providing clear, context-specific management rules that reduce overall system complexity.
2Productivity
If control information is multiplexed onto common resource structure to improve resource efficiency, then resource efficiency is improved, but transmission reliability deteriorates due to potential conflicts
Solution Approach 1:
The patent implements dynamic multiplexing decisions based on the content and type of information being transmitted. The wireless device evaluates whether control information can be successfully multiplexed onto the common resource structure, and adjusts its behavior accordingly - either multiplexing when conditions are favorable or falling back to alternative transmissions when conflicts would compromise reliability. This dynamic approach maintains high resource efficiency while protecting transmission reliability through context-aware decision-making.
Solution Approach 2:
The patent introduces an intermediary evaluation mechanism that assesses the compatibility of control information with the common resource structure before multiplexing. This intermediary layer (the content/type-based decision logic) mediates between the desire for resource efficiency and the need for transmission reliability, allowing multiplexing only when it will not compromise the integrity or success of the transmission.
3Loss of time
If higher priority transmissions are prioritized to meet latency requirements, then latency performance is improved, but resource utilization efficiency deteriorates due to dropping lower priority transmissions
Solution Approach 1:
The patent changes the parameter of transmission priority handling by introducing content and type-based multiplexing decisions. Instead of simply dropping lower-priority transmissions when conflicts occur, the system evaluates the specific content and type of control information to determine whether multiplexing is feasible. This parameter change (from binary drop/multiplex decision to conditional decision based on information characteristics) improves latency performance for high-priority transmissions while maintaining better resource utilization by multiplexing when appropriate.
