Relay UE Measurement Reporting for Wireless Path Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently reporting measurement results from candidate relay User Equipment (UE) to network nodes, particularly in complex relay scenarios.
Innovation Solution
A method and device for measurement reporting, where a remote UE receives a UE-to-Network (U2N) Relay discovery message including IDs of relay UEs and serving cells, and transmits a measurement report message to a network node, incorporating measurement results, Layer-2 IDs, and serving cell IDs of candidate relay UEs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If measurement report messages include detailed information about multiple relay UEs (measurement results, Layer-2 IDs, serving cell IDs), then the network node can select optimal relay UEs for path switching, but the message size and processing complexity increase
Solution Approach 1:
The measurement report message is segmented into multiple fields, each carrying specific types of information (measurement results, Layer-2 IDs, serving cell IDs). This segmentation allows the network node to process different types of information separately and efficiently, reducing overall processing complexity while maintaining complete relay selection capability
Solution Approach 2:
The measurement report message acts as an intermediary structure that organizes and transmits relay UE information between the remote UE and network node. By standardizing the message format with specific fields, it facilitates efficient information exchange and simplifies network node processing
2Adaptability or versatility
If the remote UE reports measurement results for multiple candidate relay UEs, then the network can make informed path switching decisions, but the information transmission overhead increases
Solution Approach 1:
Multiple pieces of relay UE information (measurement results, Layer-2 IDs, serving cell IDs) are merged into a single standardized measurement report message. This consolidation allows the remote UE to transmit comprehensive relay selection data in one message, improving adaptability while managing transmission overhead efficiently
Solution Approach 2:
The measurement report message serves multiple functions: it provides measurement results for signal quality assessment, includes Layer-2 IDs for relay UE identification, and contains serving cell IDs for network routing. This multi-functionality enables comprehensive relay selection in a single standardized message format

AI summary
A method and device for measurement reporting are disclosed. In one embodiment, a remote User Equipment (UE) receives a UE-to-Network (U2N) Relay discovery message from a first relay UE, wherein the U2N Relay discovery message includes a User Info identity (ID) of the first relay UE, a Layer-2 ID of a second relay UE, and an ID of a serving cell of the second relay UE. Furthermore, the remote UE transmits a measurement report message to a network node, wherein the measurement report message includes a measurement result of the first relay UE, the Layer-2 ID of the second relay UE, and the ID of the serving cell of the second relay UE.
