Relay UE Warning Broadcast via Indication Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is currently no clear solution for implementing a relay UE to transmit warning messages in a broadcast manner without establishing a direct link with remote UEs in U2N relay scenarios.
Innovation Solution
Introduce first indication information associated with warning messages, transmitted by relay UEs to remote UEs, to facilitate the broadcast of warning messages without requiring a direct link, using discovery messages or direct links for communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If relay UE transmits warning messages in broadcast manner without establishing direct link with remote UE, then power consumption is reduced and communication process is simplified, but there is no clear implementation solution currently
Solution Approach 1:
The patent introduces first indication information as an intermediary element that enables relay UE to broadcast warning messages to remote UE without establishing a direct communication link. This indication information acts as a mediator that carries the warning message content, allowing the relay UE to transmit alerts in a broadcast manner while maintaining the simplicity of the implementation through standardized protocol mechanisms.
2Ease of operation
If relay UE transmits warning messages in broadcast manner without establishing direct link, then communication process is simplified, but reliability of message delivery may be affected
Solution Approach 1:
The patent incorporates feedback mechanisms where remote UE sends second indication information to relay UE to confirm receipt of warning messages. This feedback loop ensures that the broadcast transmission is reliable by verifying that remote UEs have successfully received and processed the warning information, thus maintaining high reliability while keeping the communication process simple through automated confirmation.
