AI Technical Summary
Current communication systems face challenges in efficiently managing network signaling, particularly in the integration of access and backhaul functions in 5G or NR technology, which requires improved methods for transmitting F1 application protocol information across relay nodes and base stations.
The proposed solution involves extending Radio Resource Control (RRC) information transfer to transmit F1 application protocol (F1AP) messages from a donor node's central unit to the radio access network part of an integrated access and backhaul node, utilizing a specific type of signaling radio bearer (SRB) to prioritize and differentiate F1AP information.
This approach enhances the efficiency of network signaling by reducing protocol overhead in wireless transmissions, allowing for reliable transport of F1AP information and enabling self-backhauling with minimal manual effort, thereby supporting automated self-configuration in 5G or NR networks.
