5G NG-RAN Signalling
The course provides a technical description of layer 3 protocols and signalling procedures defined for the 5G radio access (‘New Radio, NR’) and radio access network (‘NGRAN’) as part of 3GPP Release-15 and Release-16. The course also covers the NR layer 2 protocols.

This course provides a technical description of layer 3 protocols and signalling procedures defined for the 5G radio access (‘New Radio, NR’) and radio access network (‘NGRAN’) as part of 3GPP Release-15 and Release-16.
The course uses a top-down approach starting with a high level description of the functionality of different network entities and the interaction needed between on different interfaces. The layer 3 protocols are then discussed one by one in detail in a logical scenario-based sequence. A number of detailed message-by-message signalling sequences will be presented during the course to tie everything together. The course also covers the NR layer 2 protocols.
Protocols and signalling procedures related to the 5GC-internal Service Based Architecture are mentioned but not covered in any detail.
NOTE: This course is not delivered with the FoldOut methodology.

Prerequisites
Basic knowledge of 5G network architecture and functions is highly recommended but not compulsory. Reasonably good technical knowledge of protocols and signaling within LTE/EPC is beneficial.
