NR Synchronization Reference Selection for LTE-Compatible Sidelink
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In current Sidelink (SL) communication systems, there is no effective method to ensure that SL devices using NR technology and SL devices using LTE technology use the same synchronization reference source, leading to potential interference due to non-synchronization.
Innovation Solution
A method and apparatus that configure an NR device or module to select a synchronization reference source using the priority criterion of LTE, ensuring consistency in synchronization reference sources across different communication technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If NR devices use NR priority criterion for synchronization reference source selection, then NR communication performance is optimized, but synchronization consistency with LTE devices cannot be ensured
Solution Approach 1:
The patent applies universality by enabling the NR device to use the LTE priority criterion for synchronization reference source selection. This allows the NR device to function universally with both LTE and NR devices using the same selection criteria, ensuring synchronization consistency across different RATs while maintaining the ability to optimize for specific scenarios when needed
2Productivity
If different RATs use different synchronization reference sources, then each RAT can optimize its own performance, but interference occurs between adjacent devices
Solution Approach 1:
The patent applies equipotentiality by making the synchronization reference source selection criteria equivalent for both LTE and NR devices. By using the same LTE priority criterion, both RATs operate at the same synchronization potential, eliminating the harmful interference that arises from adjacent devices using different synchronization references
