Priority-Based Multiplexing for Overlapping Wireless Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern wireless communication systems face challenges in efficiently managing and prioritizing overlapping communication resources for uplink transmission, particularly in 5G networks, where resource overlap can lead to interference and failure to meet latency requirements.
Innovation Solution
A method is introduced where wireless devices transmit multiplexed information blocks using a common resource structure, selecting blocks based on priority representation and a predetermined time window, allowing for efficient resource use while fulfilling latency requirements by prioritizing and multiplexing signaling, such as URLLC signaling, in 5G networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple information blocks are transmitted on overlapping resource structures, then resource utilization increases, but interference between signals increases and reliability decreases
Solution Approach 1:
The patent segments the overlapping resource structures by introducing a priority-based selection mechanism that divides transmissions into priority groups. High-priority transmissions (e.g., URLLC) are separated from low-priority transmissions (e.g., eMBB) through the priority representation field, allowing selective multiplexing of only compatible transmissions while avoiding interference between conflicting signals.
Solution Approach 2:
The patent changes the parameter of resource allocation by introducing a priority representation field that dynamically adjusts which transmissions are multiplexed together. This parameter change allows the system to adapt resource utilization based on transmission priority, ensuring that high-priority signals are always transmitted reliably while low-priority signals are multiplexed only when they do not cause interference.
2Productivity
If transmissions are multiplexed to improve resource efficiency, then productivity increases, but meeting latency requirements becomes more difficult
Solution Approach 1:
The patent applies preliminary action by evaluating transmission priorities and selecting which information blocks to multiplex before the actual transmission occurs. The priority representation field is processed in advance to determine the multiplexing configuration, ensuring that latency-critical transmissions are identified and protected from delays caused by multiplexing operations.
Solution Approach 2:
The patent introduces dynamics by making the multiplexing configuration adaptive based on transmission priorities. The system dynamically adjusts which transmissions are multiplexed together according to their priority levels, allowing flexible resource allocation that can respond to changing latency requirements while maintaining high resource efficiency.
3Quantity of substance
If overlapping resources are used to increase capacity, then quantity of transmissions increases, but interference and resource management complexity increase
Solution Approach 1:
The patent introduces an intermediary mechanism in the form of a priority representation field that mediates between multiple overlapping transmissions. This intermediary structure provides a systematic way to manage resource conflicts by encoding priority information that automatically guides the multiplexing decision process, reducing the complexity of manual resource management while allowing high capacity utilization.
