AI Technical Summary
Technical Problem
The existing 3GPP specifications for sidelink relaying do not adequately address multi-hop scenarios, lacking detailed changes to the SRAP layer to support extended connectivity and efficient data transmission in complex relay networks.
Method used
Implement modifications to the SRAP layer to support multi-hop scenarios by introducing explicit configurations for 'last', 'intermediate', and 'first' Relay UEs, including additional UE ID fields and next-hop information, and adapting SRAP operations to handle end-to-end bearers and hop-by-hop functions.
Benefits of technology
Enables efficient multi-hop sidelink relaying by ensuring proper data routing and identification across multiple relay nodes, enhancing network connectivity and reducing operational complexity.
