My friend: Hi Soumya, we found a problem during last drive test done for one 5G site as 5G DL PDCP throughput was less than previous drive although EN-DC was active in both cases?
Me: I think you mean split bearer not EN-DC, right?
My friend: Are they different?
Me: Yes, as EN-DC is a feature to allow 5G users to have dual connectivity for both 4G and 5G networks. Without it, 5G users will be kept on 4G network and won’t be connected to 5G network. It is activated at the eNB side.
My friend: So, what is split bearer?
Me: It is a feature that is activated at the gNB side to control the DL data coming from the EPC to be transmitted either at the 5G air interface only or 4G air interface only or both 4G and 5G air interfaces simultaneously. Of course, last option will have the highest possible throughput. So, I think you checked EN-DC parameters and not the split bearer, so please check it.
My friend: Yes, you are right, I checked it and split bearer was set to 5G only at the last DT, while it was previously set to both 4G+5G. Thanks a lot.
Me: Take care about it as this is very important and many engineers are mixing them.
