Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently forwarding sidelink User Equipment (UE) capability information, particularly in next-generation networks like 5G, where UE-to-UE Relay mechanisms are needed to support communication between devices that cannot directly communicate.
Innovation Solution
A method and device for a UE-to-UE Relay to forward sidelink UE capability information, where the Relay receives and transmits the capability information of one UE and its own capability information, or combines them to derive a combined capability information, enabling effective communication through the Relay.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If UE-to-UE Relay forwards sidelink UE capability information, then communication between devices that cannot directly communicate is enabled, but device complexity increases due to additional relay mechanisms
Solution Approach 1:
The patent introduces a UE-to-UE Relay as an intermediary device that forwards sidelink UE capability information between UEs that cannot directly communicate. The relay receives capability information from one UE and transmits it to another UE, enabling indirect communication while maintaining the existing UE capability information structure without requiring complex modifications to UE devices.
2Productivity
If combined sidelink UE capability information is transmitted, then communication efficiency is optimized by providing comprehensive capability data, but information processing complexity increases
Solution Approach 1:
The patent describes transmitting combined sidelink UE capability information that merges the relay's own capability information with the capability information of the first UE. This combination provides the second UE with comprehensive capability data in a single transmission, optimizing communication efficiency by eliminating the need for separate capability information exchanges while the standardized combination process maintains manageable processing complexity.

AI summary
A method and device are disclosed from the perspective of a User Equipment-to-User Equipment (UE-to-UE) Relay to forward sidelink UE capability information. In one embodiment, the method includes the UE-to-UE Relay receiving a first sidelink UE capability information from a first UE. The method further includes the UE-to-UE Relay transmitting the first sidelink UE capability information of the first UE and a second sidelink UE capability information of the UE-to-UE Relay to a second UE or transmits a combined sidelink UE capability information to the second UE, wherein the combined sidelink UE capability information is derived from the first sidelink UE capability information and the second sidelink UE capability information.
