Hi Experts,

What are the common causes of high UL PDCP loss compared to DL PDCP packet loss?

2

T reordering too low
Make it like 300 ms.

3

Any other causes?

4

Tdiscard you can check.
I find in ZTE they have parameter tdiscard for Uplink as well.
But not find it for Nokia, other vendors guy can comment.

I can see only for DL in Samsung.
