NR-NTN setup with Test Equipment, OAI UE can't decode SIB2 or SIB19

Hi, I’m trying to verify NR-NTN interoperability with OAI-UE and Test Equipment (5G Network Emulator), OAI UE fails to decode SIB2 or SIB19 (Other SI). The test setup contains a Linux (Ubuntu 24.04.1 LTS) PC + USRP B210 as OAI UE, and RF cable directly connect to Network Emulator which has internal Channel Emulator function. The USRP B210 uses external 10MHz clock from Network Emulator.

I used NR_gNB_SIB2 branch / latest commit 789766b2

Command used to run nrUE:

sudo ./nr-uesoftmodem -O ~/uxm_ue.conf --band 3 -C 1830000000 --CO -95000000 -r 106 --numerology 0 --ssb 526 --time-sync-I 0.1 --autonomous-ta --ue-rxgain 100 --clock-source 1 --T_stdout 2 | tee ue_ntn_othersi.txt

From UE log I can see below error message:

[NR_MAC]   Got NACK on NR-BCCH-DL-SCH-Message (other SI)

Please find below attachment including UE conf file, UE log and Test Equipment log in pcap format (can be directly opened in Wireshark and check MIB/SIB1/SIB2/SIB19...):
