Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The LTE sidelink and NR sidelink multi-mode communications in wireless communication technologies face issues such as data sending and receiving conflicts, power limitations, and interference due to their half-duplex working mode, especially when operating without harmony, leading to potential signal modulation distortion and harmonic wave interference.
Innovation Solution
A multi-mode communication method where terminals and network side devices exchange resource-related information to coordinate data transmission across different communication modes, including resource allocation, synchronization, and interference sensing, enabling effective scheduling and conflict resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If LTE sidelink and NR sidelink multi-mode communications work simultaneously, then communication versatility is improved, but data sending and receiving conflicts occur due to half-duplex working mode
Solution Approach 1:
The terminal performs sensing operations in advance to detect available resources and potential conflicts before actual data transmission. Resource selection and coordination decisions are made based on pre-acquired channel state information, preventing conflicts before they occur
Solution Approach 2:
The system implements sensing mechanisms where terminals continuously monitor the channel and provide feedback information about resource availability. This feedback loop enables dynamic adjustment of transmission parameters to avoid conflicts between different communication modes
2Productivity
If data is transmitted under different modes at the same time, then communication productivity is improved, but signal modulation distortion and harmonic wave interference occur
Solution Approach 1:
The system segments transmission resources in time and frequency domains, dividing available resources into separate portions for different communication modes. This segmentation prevents simultaneous transmission that would cause interference while maintaining high overall productivity
Solution Approach 2:
The system employs periodic transmission patterns with coordinated timing between different communication modes. By scheduling transmissions in periodic intervals and avoiding overlapping time slots, the system maintains high data rates while preventing signal distortion and interference
3Reliability
If resource coordination between sidelink interface and Uu interface is implemented, then communication reliability is improved, but device complexity increases
Solution Approach 1:
The sensing mechanism serves multiple functions simultaneously: it detects channel availability, identifies potential conflicts, provides feedback for resource selection, and coordinates between different interfaces. This multi-functionality reduces the need for separate coordination mechanisms, managing complexity while maintaining reliability
