[E2 agent] E2AP README update and OAI-FlexRIC CI pipeline improvements
- E2AP README - add OSC nearRT-RIC section; update with proper FlexRIC
links, and explanations on prerequisites, as well as for xApps
- OAI-FlexRIC CI - use separate containers for xApps
- add reference files for CU-UP/CU-CP
- add logging for KPM NSSAI condition
1. Closes#884 - increase the XRAN_MAX_FRAGMENT from 4 to 6 (sufficient for MTU 1500 with compression 8b)
2. Add new firmware version that supports jumbo frames
3. Update the config file to align with the new Liteon unit in our lab - center frequency, jumbo frames, compression and RU MAC address,
as well as the max DL MIMO layers.
After capturing the FH packets, we observed that the RU supports the MTU value for jumbo frames.
Therefore, no fragmentation needed on DL.

Add support for 'dl_min_mcs' and 'ul_min_mcs' configuration parameters
Add support for 'dl_min_mcs' and 'ul_min_mcs' configuration parameters,
they will enforce the gNB scheduler to select always a MCS equal or
above its values
In addition to use a min value for MCS, this MR also enables the testing
of a specific MCS value with COTS UE, by setting
xl_min_mcs = xl_max_mcs
example:
dl_min_mcs: 22
dl_max_mcs: 22
ul_min_mcs: 7
ul_max_mcs: 7
In the example above, the scheduler will use always MCS 22 for downlink
and MCS 7 for uplink.
RedCap InitialBWP
Prevent RedCap UEs to move to DedicatedBWP
This allows the coexistence of RedCap UEs and non-RedCap UEs in the
same cell by having an InitialBWP with 20MHz and a larger
DedicatedBWP.
Update example RedCap configuration file to have 20 MHz InitialBWP and
40 MHz DedicatedBWP
FHI72: Management plane support
At the moment, tested with Benetel 550 and 650 RUs FW v1.2.2
- support for multiple RUs
- RPCs implemented: <connect>, <subscribe>, <get>, <supervision-watchdog-reset>,
<edit-config>, <validate>, <commit>, <disconnect>
- read PTP sync status from operational datastore xml
- get vendor name, and for xran store RU MAC, MTU and IQ bitwidth and PRACH
offset, and transfer this info
- store interface name, low-level-tx/rx-endpoint names, tx/rx-carrier names,...,
from operational datastore xml
- add reference gNB/DU config files with M-plane support
- update FHI readme
fix NTN LEO scenarios
- gNB: add support for NTN parameter ta-CommonDrift-r17
- NR UE: fix application of NTN TA information
- NR UE: add command line parameter ntn-initial-time-drift to compensate
time drift during initial sync
- NR UE: fix writeTimestamp inconsistencies
- NR UE: add MAC state UE_RECEIVING_SIB ensuring to start RA only after
successfully receiving SIBs
- rfsimulator: update earth radius for LEO simulation to match UE
position in ue.conf file
- update conf files for NTN LEO scenario
- update description how to run NTN scenarios in RUNMODEM.md
- fix: ta-Common is a round-trip-time, not a one-way delay
- NR UE: simplify calculation of next_tx_slot_and_frame by moving up
assignment of duration_rx_to_tx
- cellbarredNTN indicates notbarred in SIB1 if NTN access is available
- Removed b66 NTN and enabled B254 NTN conf file in CI
- NR UE: RRC layer now explicitly tells MAC layer when the RA procedure
can be started
- move NTN LEO config to band 254 and update doc/RUNMODEM.md
Closes#901
Fix yaml example config file
amf_ip_address is decoded as a paramlist_def_t and not as a paramdef_t,
so in the config file it should be a list of ip addresses
In current develop just by trying to run this config file with:
sudo ./nr-softmodem -O ../../../targets/PROJECTS/GENERIC-NR-5GC/CONF/gnb.sa.band78.fr1.106PRB.usrpb210.yaml
results in a segfault.
Config files improvements for PRACH
Some PRACH parameters in configuration files are not properly set.
- number of SSB per RACH occasion should be 1 when we have only 1 SSB
(it would still work with 1/2 but it makes little sense and might
limit UE selection of ROs).
- some PRACH configuration indices would generate PRACH conflicting with
PUCCH and therefore reducing scheduling capabilities
Further cleanup of some config files still using deprecated fields
- Removed ntn_koffset, ntn_ta_common, ntn_ta_commondrift arguments in order to be used directly from SIB19
- Removed global NTN_UE_Koffset variable and it's use
- Introduced getter functions for ntn related parameters
