UE Type Switching With Interruption-Aware Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication technologies face challenges in efficiently managing UE type switching between Type 1 and Type 2 architectures, particularly in minimizing disruptions and optimizing resource utilization during the switching process.
Innovation Solution
A scheme for UE type switching is introduced, where a terminal device transmits capability information to a network device, which then sends an indication for type switching. The terminal device performs the switching based on the indication and a requirement for an interruption, allowing the network to adjust scheduling accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If UE type switching is performed without coordination, then switching flexibility is improved, but transmission failures increase
Solution Approach 1:
The terminal device determines interruption requirements before performing UE type switching. By pre-assessing the interruption caused by switching and communicating this to the network device, the system can prepare appropriate scheduling adjustments in advance, preventing transmission failures while maintaining switching flexibility.
Solution Approach 2:
The terminal device feeds back interruption requirement information to the network device before switching. This feedback mechanism allows the network device to adjust scheduling proactively, ensuring reliable transmission during the switching process while maintaining the ability to switch between UE types.
2Reliability
If UE type switching is performed with strict scheduling control, then transmission reliability is improved, but resource utilization decreases
Solution Approach 1:
Instead of implementing strict scheduling control for all transmissions, the system applies scheduling adjustments only to resources affected by UE type switching. This partial action approach maintains transmission reliability for critical resources while leaving other resources available for normal utilization, avoiding excessive scheduling constraints.
Solution Approach 2:
The system dynamically adjusts scheduling parameters based on the specific interruption requirements of UE type switching. By changing scheduling parameters selectively rather than applying uniform strict control, the system maintains reliability where needed while preserving resource utilization elsewhere.
3Speed
If UE type switching is performed without interruption consideration, then switching speed is improved, but scheduling optimization is reduced
Solution Approach 1:
The terminal device determines interruption requirements in advance before performing UE type switching. This preliminary assessment allows for rapid switching execution while the network device simultaneously prepares optimized scheduling based on the known interruption requirements, achieving both speed and optimization.

AI summary
Embodiments of the present disclosure relate to UE type switching. In an aspect, a terminal device transmits, to a network device, capability information indicating support of a plurality of types of the terminal device. Then, the network device transmits an indication for switching a type of the terminal device to the terminal device. Moreover, the terminal device performs type switching based on the indication and a requirement for an interruption caused by the type switching. In this way, it is allowed to avoid transmission failure due to the interruption caused by type switching, and thus improve resource utilization and transmission flexibility.
