Relay UE Validity Check for Protected End-to-End Discovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In user equipment (UE)-to-UE relay communication, there is a challenge in ensuring the validity of protected end-to-end discovery information, which can become invalid or expired over time, leading to potential transmission of incorrect information.
Innovation Solution
A method where a relay UE receives and stores validity information associated with protected end-to-end information from a target end UE, performs a validity check, and selectively transmits this information based on the check results, ensuring only valid information is transmitted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If protected end-to-end discovery information is transmitted in UE-to-UE relay communication, then the functionality and connectivity of the communication system is improved, but the information may become invalid or expired over time leading to transmission of incorrect information
Solution Approach 1:
The patent applies preliminary action by embedding validity information (such as expiration timestamps or validity periods) into the protected end-to-end discovery information before transmission. This allows the receiving UE to proactively determine whether the information is still valid without requiring additional verification communications, thus maintaining both the functionality of relay communication and the reliability of transmitted information.
2Reliability
If validity checks are performed on protected end-to-end information, then the reliability of transmitted information is improved, but the complexity of the communication process increases
Solution Approach 1:
The patent extracts the validity information as a separate, distinct element from the main protected discovery information. By taking out the validity check mechanism into a standalone component (such as a separate field or message element), the system can perform reliability verification without significantly increasing the overall communication process complexity, as the extracted validity data can be checked independently and efficiently.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a relay user equipment (UE) may receive a message including protected end-to-end information associated with a target end UE. The relay UE may store validity information associated with the protected end-to-end information associated with the target end UE. The relay UE may perform a validity check for the protected end-to-end information based at least in part on the validity information. The relay UE may selectively transmit the protected end-to-end information associated with the target end UE based at least in part on a result of performing the validity check. Numerous other aspects are described.
