Radio Resource Allocation via Group Classification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-radio link communications systems face inefficiencies in resource utilization and quality of service due to high power consumption and signaling complexity, particularly when accessing resources with significantly different data rates, leading to performance impairments and buffer overflows.
Innovation Solution
A method and apparatus that optimize resource allocation by assigning available resources to sets based on common properties, allowing subscriber stations to select resources with comparable data rates for parallel transmission, and dynamically update resource assignments based on current network usage and availability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a subscriber station scans all available resources in different radio access possibilities, then resource selection capability is improved, but power consumption and signaling complexity increase significantly
Solution Approach 1:
The network side performs preliminary classification of available resources into sets based on common properties (data rate, latency, reliability) before the subscriber station needs to select resources. This pre-organization eliminates the need for the subscriber station to scan all resources individually, reducing power consumption while maintaining adaptability.
Solution Approach 2:
A coordination device acts as an intermediary between the network and subscriber station, providing classified resource information to the subscriber station. This intermediary organizes and presents resource information in a structured manner, reducing the signaling complexity and power consumption for resource selection.
2Productivity
If resources with significantly different data rates are used for parallel transmission, then resource utilization is improved, but performance impairment and buffer overflow risk increase
Solution Approach 1:
Resources are classified into sets based on their local properties (data rate characteristics, latency, reliability). The subscriber station then selects resources from appropriate sets that have comparable properties, ensuring that each resource in the parallel transmission has similar quality characteristics, which prevents performance impairment and buffer overflow.
Solution Approach 2:
The system changes the parameter of resource selection by introducing set-based classification with common properties. Instead of selecting resources based on raw data rate alone, the system groups resources by multiple parameters (data rate, latency, reliability) to create sets of comparable resources, thereby maintaining performance stability while utilizing available resources efficiently.
3Productivity
If switched MRTD is used to transmit data packets alternatively via one resource, then resource efficiency is improved, but switching delay and signaling complexity increase
Solution Approach 1:
Resources are pre-classified into sets with common properties before data transmission begins. This preliminary organization allows the subscriber station to quickly select appropriate resources without performing complex scanning or evaluation during transmission, reducing switching delay while maintaining resource efficiency.
Data Source
AI summary
An item of network information pertaining to available resources, which are available for transmitting radio communication data in a multi-radio link communications system, is transmitted to network devices and/or subscriber stations by a coordination device. The item of network information assigns the available resources to groups, and the resources of different groups are assigned according to at least one common group feature.
