Which downlink data split modes are supported on the gNodeB side in the 5G NSA Option 3x architecture? (Choose All that Apply)

Show Suggested Answer Hide Answer
Suggested Answer: A, D

According to the Huawei SA Networking Product Design Guide (https://www.huawei.com/en/doc/e_huaweidoc/pdf/HW_051525), the downlink data split modes supported on the gNodeB side in the 5G NSA Option 3x architecture are A. MCGONLY: only split to the MCG and D. SCGANDMCG: dynamic data split. The MCGONLY mode is used when all the UE data must be sent to the same MCG, while the SCGANDMCG: dynamic data split mode is used when the data is split between multiple SCGs and MCGs.

C is not really applicable, right? Only SCG seems limiting.

I’m pretty certain that SCG_AND_MCG refers to dynamic data split, but I need to double-check my notes on that.

I feel like SCG_ONLY could be an option too, but I can't recall if it's specifically for the gNodeB side in this context.

I remember practicing a similar question, and I think SCG_AND_MCG might refer to static data split, but I could be mixing it up.

No problem, I've got a good handle on this. The key is remembering that MCG_ONLY is just the master cell, SCG_AND_MCG (static) is a fixed data split between the two, and SCG_AND_MCG (dynamic) allows the split to change during the session. I've got my strategy down.

Wait, I'm a bit confused. I know the MCG and SCG are the master and secondary cells, but I'm not sure I fully grasp the static versus dynamic data split concepts. Maybe I should ask the professor for some clarification before the exam.

I've got this! The 5G NSA Option 3x architecture supports MCG_ONLY, SCG_AND_MCG (static), and SCG_AND_MCG (dynamic) data split modes on the gNodeB side. Time to mark those down.

Okay, let me see if I can break this down. The key is understanding the differences between MCG, SCG, static, and dynamic data splits. I'll need to review my 5G notes to make sure I have that straight.

Hmm, this looks like a tricky 5G networking question. I'll need to think carefully about the different downlink data split modes and how they apply to the NSA Option 3x architecture.
