Hello NR experts!
Please help me with the next question. I’m using one computer with 5G OAI + usrp_b210 as gNodeB and second computer with 5G OAI + usrp_b210 as UE.
I need to use PRACH preamble format0 in n1 band. When prach_ConfigurationIndex is set to 61 ( or any other Index for PRACH preamble format3) everything is working fine.
But when prach_ConfigurationIndex is set to 1 (or any other Index with format-0 ) gNodeB doesn’t see msg1. UE reports : RAR reception failed .
Format-3 and format-0 have the same length, but bandwidth of format-0 is different.
Is it possible to use PRACH preamble format0 in n1 band?
Thanks!
