Wireless Communication Group QoS Flows for Coordinated Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems struggle to ensure overall quality of service (QoS) for a group of nodes, particularly in scenarios like federated learning, where network resources are limited and there are variations in communication quality and computational capabilities among devices.
Innovation Solution
Introduce a wireless communication method that allows for transmitting and receiving information associated with group-based QoS, enabling flexible resource allocation and scheduling across terminal devices and QoS flows to ensure consistent performance for groups of nodes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the network allocates resources for QoS flow of each terminal device individually, then transmission quality of each terminal device is ensured, but overall transmission quality of a group of nodes cannot be ensured
Solution Approach 1:
The patent segments QoS management into two levels: individual terminal device QoS flows and group-level QoS flows. The group QoS flow is a separate entity that aggregates multiple terminal device QoS flows, allowing independent resource allocation and quality control at the group level while maintaining individual device QoS guarantees.
Solution Approach 2:
The patent introduces a group QoS flow as an intermediary layer between the network and multiple terminal devices. This group QoS flow acts as a mediator that receives resources from the network and distributes them to individual terminal devices, enabling coordinated resource management and ensuring both individual and overall transmission quality.
2Reliability
If network resources are allocated to ensure QoS for each terminal device, then individual transmission quality is maintained, but resource utilization efficiency decreases in group service scenarios
Solution Approach 1:
The patent merges multiple terminal device QoS flows into a single group QoS flow. This consolidation allows the network to allocate resources to the group as a whole rather than managing each device separately, improving resource utilization efficiency while maintaining the ability to guarantee quality for individual devices when needed.
Solution Approach 2:
The group QoS flow serves multiple functions: it manages resources for multiple terminal devices collectively, provides overall QoS guarantees for the group, and can still allocate resources to individual devices within the group. This multi-functionality resolves the contradiction by enabling both efficient resource utilization and reliable transmission quality.
3Reliability
If data from all nodes in a group is collected simultaneously, then overall QoS for the group is ensured, but device complexity and coordination overhead increase
Solution Approach 1:
The group QoS flow acts as an intermediary that simplifies coordination by providing a single point of management for group resources. Instead of each terminal device needing to coordinate independently with the network, the group QoS flow handles resource allocation and synchronization, reducing coordination overhead while ensuring simultaneous data collection from all nodes.
