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
