- encode all SI containers the encoding function gets (it's not the
encoding function's job to enforce semantics)

Fixes: 30628b820c ("Add encoding/decoding lib for F1AP Setup Response
(Interface Management)")
In various places, e.g., during initialization (before deployment), we
use the name of the CN object, previously including the IP address.
However, the IP might not be available (because the CN is not deployed),
so we would get warnings at this stage. Avoid this by not looking up the
IP.
There is now one place where we have to look up the IP address
separately.
Also, the exception in initialization might be misleading if we used
{self}, because we complain about no node being present, but the {self}
would include a non-existing node name => do not use it.
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.
Encapsulate the asn1c call from cmake in a cmake function run_asn1c().
As a notable change to the previous manual add_custom_command()
invocation, in suppresses the output of asn1c by default [1] and stores
it in a log file. In case of asn1c4 error, the output will output on
stdout.
Use the new run_asn1c() in all occasions for code generation.
[1] it is quite verbose, with many warnings that we cannot influence nor
suppress, and lists all generated files which is verified by the build
system automatically, anyway.
NR UE: enable concurrent UL slot processing
This commit introduces support for concurrent UL slot processing
Key changes:
- Increased number of UL actors from 1 to 2
- fix several issues related to writing to global variables inside processSlotTX
- Ensure in-order execution of if_module calls by utilizing the preexisting dynamic_barrier structure.
Note: for NTN, concurrent UL slot processing does not work. A flag
`--num-ul-actors X` has been introduced that allows to fix the number of
UL actors to `X` (default is 2).
Add 5GMM Service Reject enc/dec library and unit test
- introduce the library for the NAS Service Reject enc/dec
- add relevant unit test
- add handler
nr_dlsim allocates memory on every SNR iteration without freeing it.
This can lead to memory exhaustion. Fix this by allocating only once
and reuse memory. Also, free it before exit.
NR UE: fix PRACH generation with frequency resource id not 0 when msg1-FDM > 1 in SIB1
When msg1-FDM > 1 (2, 4 or 8) in SIB1, the frequency resource id of
PRACH could be not 0, current PRACH generation only considers frequency
resource id = 0. This MR fixes it, verified with 3rd-party gNB.

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
esp. for LEO NTN scenarios the timing drifts during initial sync, which is mostly compensated with --ntn-initial-time-drift.
But there might be a residual time offset, and by extending the peak search window we make this more tolerant.
Depending on the main source of frequency offset, pre-compensate the UL frequency offset (FO) accordingly.
Therefore modify the flag `--cont-fo-comp` to accept an integer value, where
- `1` specifies, that the main FO contribution comes from the accuracy of the local oscillator (LO)
- `2` specifies, that the main FO contribution comes from Doppler shift
