Auxiliary Scheduling Reporting for NR-Light IoT Load Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current NR systems are not optimized for Internet of Things (IoT) devices, particularly in supporting NR-Light users with smaller bandwidth and fewer antennas, which limits the ability to simultaneously serve both NR-Light and other users on the same carrier, and the initial bandwidth part (BWP) load capacity is insufficient for mass-connected IoT devices.
Innovation Solution
A method and device for reporting auxiliary scheduling information through Msg1, Msg3, and MsgA, which includes transmission Power Headroom Report, Data Volume, and channel state information, configured and indicated in system information, to enable early reporting and efficient resource allocation for NR-Light users, allowing for simultaneous support of multiple users on the same carrier.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the initial bandwidth part (BWP) is configured to support NR-Light users with smaller bandwidth, then the adaptability to IoT devices is improved, but the load capacity of the initial BWP becomes insufficient for mass-connected IoT devices
Solution Approach 1:
The patent divides the initial BWP into multiple sub-BWPs, each capable of independently serving different user groups. This segmentation allows the system to maintain small bandwidth requirements for NR-Light IoT devices while providing additional sub-BWPs to handle the aggregate load from mass-connected devices, thereby resolving the contradiction between adaptability and load capacity.
2Device complexity
If the system is optimized for NR-Light users with fewer antennas, then the device complexity is reduced, but the ability to simultaneously serve multiple user types on the same carrier deteriorates
Solution Approach 1:
The patent applies local quality by assigning different antenna configuration requirements to different sub-BWPs. Specifically, certain sub-BWPs are configured for NR-Light users with fewer antennas, while other sub-BWPs support full-featured users with more antennas. This allows the system to reduce complexity for IoT devices in specific frequency regions while maintaining full capability in other regions, thereby serving multiple user types simultaneously.
