NR-U Scheduling Method Using Dedicated Parameter Groups
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing time domain resource assignment method in multi-TTI scheduling for NR-U is inflexible, limiting the ability to efficiently manage and allocate resources for physical channels.
Innovation Solution
A scheduling method that involves sending downlink control information (DCI) with first indication information to indicate a resource allocation set, which determines the transmission parameters of physical channels, including a dedicated transmission parameter group for each channel, allowing for flexible adjustment of channel parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the existing time domain resource assignment method in multi-TTI scheduling for NR-U is used, then the scheduling can be performed for multiple physical channels, but the method is inflexible and cannot efficiently manage and allocate resources
Solution Approach 1:
The patent segments the resource allocation by introducing separate parameter groups for different physical channels (first parameter group for first physical channel, second parameter group for second physical channel). Each parameter group can be independently configured and scheduled, allowing flexible resource management while maintaining high allocation efficiency through dedicated control for each channel type.
2Ease of operation
If the existing time domain resource assignment method is used, then the scheduling can be performed, but the signaling overhead is high due to repeated application of S and L parameters in each scheduled slot
Solution Approach 1:
The patent merges the parameter configuration into unified parameter groups that can be applied across multiple slots and channels. Instead of repeatedly signaling S and L parameters in each slot, the invention combines these into parameter groups that cover multiple time domains, reducing signaling overhead while maintaining ease of scheduling operation through centralized parameter definition.
3Adaptability or versatility
If the existing time domain resource assignment method is used, then the scheduling can be performed for multiple slots, but the method cannot support mini-slot level scheduling
Solution Approach 1:
The patent introduces dynamic parameter groups that can be flexibly configured for different time granularities. The parameter groups can adapt to various scheduling granularities including mini-slots, allowing the system to switch between different time domain resolutions dynamically. This enables fine-grained scheduling control without permanently increasing device complexity, as the enhanced configuration is only activated when mini-slot scheduling is required.
