Hello 5G Experts,
For NSA n/w, I have an LTE anchor site MCG in 2.3 GHz band and 5G NR mmwave SCG in the 38Ghz. band.
In the rrc reconfiguration, I can see the PDCP entity allocated in 5G but there is no 5G mmwave coverage at the Cell edge as expected and no B1 event for SCG addition in Phy layer,.
So the Flow goes like 5G PDCP>4G RLC-MAC> 4G PDSCH
And in the cell center I have good 5G mmwave coverage and so the flow does like
5G PDCP>5G RLC-MAC> 5G PDSCH.
My question is, what is the criteria for allocating 5G NR PDCP entity ?
What I observe is that PDCP entity allocation does not have a dependency on 5G coverage presence. Is it a default 5G PDCP allocation for all LTE anchor sites with X2 to gNB ?
