In view of continued dependency on faculties to update course content and various other macro factors, ApnaCourse Online Courses will be shut down from Dec 15th 2022. Only Exams by ApnaCourse will continue. We thank you for the patronage to our courses since 2013. We shall revisit online learning with a different business model in due course.

5G NR Signaling


In this course, we will discuss the 5G Signaling, which provides a comprehensive overview of 5G specific signaling and protocols. The L3 protocols are then discussed one by one in detail in a logical scenario-based sequence. After this the L2 radio interface protocol functionality is described, focusing on scheduling and reliability issues (ARQ and HARQ). An overview of the signaling and HARQ aspects of L1 is also included to give the student a complete view of the 5G protocol stack.

We will discuss the following topics :

  • Non Access Stratum (NAS) and Access Stratum (AS) Signaling between the 5G UE,  the 5G Core network and and 5G RAN respectively.

  • The concept of User Plane (UP) and Control Plane (CP) Protocols: Since in 5G we are introducing a concept of Control User Plane Separation (CUPS) so we will see that does it bring any changes in the protocol stack.

  • The role of Radio Link Control (RLC), Radio Resource Control (RRC), Packet Data Convergence Protocol (PDCP) & a new protocol specifically introduced for 5G new radio which is Service data adaptation protocol (SDAP)

  • Understanding the UE states in 5G and the difference it has with the existing LTE UE states gives a better view of how things have changed or modified.

Course Overview

In this course the participant will understand the air interface and the protocol architecture for 5G. Discussion about the protocols, control plane and user plane stack for different interfaces will be done. We will also cover the protocol stack for non 3GPP untrusted access signaling and control plane stack.

Most courses are self paced courses with a free access of 30 days. The 30 days access (basic plan) is only on the videos. To extend access by 180 days or to get course specials like question bank, course completion certificate, exam etc, you will have to enrol into the standard (paid) plan.

Yes. If your access to a course expires, you can extend that through an online payment and continue from where you left of.

We engage only experienced and certified faculties for each course. Each faculty has decades of relevant teaching / training experience that they bring to ApnaCourse. For details of our faculty partners, please visit the Faculty section in the website.

We offer a course completion certificate on most courses. This certificate is jointly given by our partner trainer or training instiute who delivered the course.

For any course specific doubts, there is an Online forum on ApnaCourse called Social Circle for every Course. Access to the Social Circle is available only in the paid plan.
