In NSA, how to measure Ping pong between B1 and A2

First of all, put some offset between (B1 and A2) them at least 8 dB.

Any solid measurements here like counter maybe?

Instead of field measurements, I mean.

There will be no ping pong if you make proper offset as suggested by @RFSpecialist.

Yes, totally agreed.

I just want to know is there any measurements to prove it from stats instead of field measurements.

You have for SCG addition:

L.NsaDc.SgNB.Add.Succ: total number of successful SgNB additions for UES that treat the local cell as their PCell in the LTE-NR NSA DC state.

But can’t find for removal of SCG.

That’s the point.

This is in 4G counters try also 5G counters.

Maybe it is there.

I couldn’t find from 5G as well so far.

But let me double double check.

A2 is inter-freq HO, B1 is iRAT HO, right?

B1 NR is to add SCG.

A2 NR is to remove SCG.

So B1 should be like -116 dBm and A2 something like -124 dBm.

But it depends on bands.

Also time to trigger hyst etc.

A2 is for start looking handover it may be both for inter - freq and intra-freq.

After A2, event A5 occurs for inter-freq.
