Hi, currently we don't support HO. We are planning to add this feature, however I cannot say with certainty when.

Hello Katerina, 

I am sorry I am a bit confused. I have seen on the publications that indicating the handover is supported. I assume It is possible by using NR PHY/MAC and LTE module RRC layers. 
Is my understanding correct?

Hi, 
HO is supported in the LENA module (LTE). 
5G-LENA module currently uses the LTE RRC and it does not support HO, however we are working on it and in the future we are planning to have our own RRC and support HO functionality.

Hi, 
Just to confirm, Can I use LTE RRC frome LENA module with NR PHY/MAC and simulate handover?
Thanks,
Cagri

Unfortunately no. Below is the answer I did get that time. I am not sure if there is a solution currently.

 No, 
NR module currently uses LTE RRC but it does NOT support handover.”

Hi Katerina,

Have you made any progress as far as HO concerns? Do you have any idea when it will be available?

Best regards,
Franci

Hi Franci,
We plan to add it in the future, but unfortunately I cannot say when. Most probably it will be after summer, but still I am not sure.

Hi,
does this mean that there is currently also no way to detach a UE from a gNodeB and attach it to another while the simulation is running?
Thanks
