5G Resource Set Configuration for Scheduling Flexibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The 4G LTE technology has limited scheduling flexibility in the time and frequency domains due to restricted resource allocation, which is not fully exploited in 5G systems, leading to insufficient resource configuration options with increased signaling overhead.
Innovation Solution
Configuring different sets of resources corresponding to various configurations in domains such as DM-RS mapping type, BWP, component carrier, serving cell, transmission waveform, or multiple access schemes, allowing for increased flexibility without additional PHY signaling overhead.

Engineering Contradiction Analysis
1Adaptability or versatility
If multiple resource sets are configured for different PHY channel configurations, then scheduling flexibility is enhanced and resource allocation options are doubled, but device complexity and configuration overhead increase
Solution Approach 1:
The resource configuration is segmented into multiple independent resource sets, each associated with specific PHY channel configurations (e.g., DM-RS mapping types, BWP configurations, component carriers). This segmentation allows the system to select appropriate resource sets based on the specific channel configuration, enhancing scheduling flexibility while managing complexity through modular organization.
Solution Approach 2:
The system dynamically selects which resource set to use based on the active PHY channel configuration. Rather than using a fixed single resource set, the resource configuration adapts dynamically to match the current channel settings, allowing the scheduler to optimize resource allocation for each specific configuration scenario.
2Device complexity
If resource allocation is restricted to a single resource set, then device complexity is reduced, but scheduling flexibility and resource configuration options are insufficient
Solution Approach 1:
Multiple resource sets are configured to serve different PHY channel configurations, creating a universal resource allocation framework. Each resource set is designed to handle specific configuration scenarios (different DM-RS mapping types, BWPs, component carriers, serving cells, transmission waveforms, or multiple access schemes), allowing the system to universally support diverse 5G NR configurations while maintaining manageable complexity through structured organization.

AI summary
Embodiments of the application provide a method for multiple resource set configuration. A device of the network obtains a configuration associated with a physical layer (PHY) channel, then the device selects a set of resources corresponding to the configuration from a plurality of resources and determines an actual resource from the selected set of resources to cause another device to transmit or receive a corresponding PHY signal on the determined actual resource.
