Terminal Frequency Information Reporting for Wireless Relay Sidelink
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in managing frequency information for relay and device-to-device (D2D) operations, particularly when the frequencies for relay services and D2D operations differ, leading to interference and reduced service quality.
Innovation Solution
A method where a terminal generates and transmits separate frequency information for sidelink operations, including both relay and D2D operations, allowing the network to schedule and manage frequencies effectively, thereby reducing interference and enhancing service quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate frequency information for relay and D2D operations is transmitted, then service quality and reliability are improved, but device complexity and signaling overhead increase
Solution Approach 1:
The patent segments frequency information into two distinct types: first frequency information for D2D operations and second frequency information for relay operations. This segmentation allows the network to separately manage and control frequencies for different operational modes, preventing interference between D2D and relay services while maintaining clear signaling structures. The terminal device transmits both types of frequency information to the network, enabling differentiated frequency management.
2Object-affected harmful factors
If frequency information is separately managed for relay and D2D operations, then interference is reduced and service continuity is improved, but system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing frequency management into separate domains: one for D2D operations and another for relay operations. Each operation type has its dedicated frequency information that can be independently configured and managed by the network, thereby preventing mutual interference between these two critical functions while maintaining manageable system complexity through structured separation.
Solution Approach 2:
The patent implements local quality by assigning specific frequency characteristics to specific operational contexts. The first frequency information is optimized for D2D communication requirements, while the second frequency information is optimized for relay operations. This context-specific frequency allocation ensures that each operation type operates on frequencies suited to its performance requirements, reducing interference through localized frequency domain separation.
