Enable SSB-SINR based CSI reporting
3GPP 38.331 release 16 specifies that If the field reportQuantity-r16 is present,
UE shall ignore reportQuantity (without suffix). reportQuantity-r16 configures
SSB based SINR as the reporting quantity.
set do_SINR = 1; in gNB params part of the config file to enable SSB based SINR
reporting.
Cleanup and refactor initial gNB configuration
This is follow-up on !3048 (merged). Major changes in this MR:
- Add config functions to reduce redundant code repeated in multiple places in the file
- Add macros to reduce redundant code in gNB configuration
- Refactor RCconfig_NR_NG
- Cleanup obsolete and commented out code
- Refactor includes in executables/nr-gnb.c
- Introduce platform type plmn_id_t for consistency across the stack: F1AP, NGAP can now use the same struct type
- And other minor formatting
This commit refactors the TUN interface management by moving its creation
and configuration from the PDCP layer to the SDAP layer for UE.
Key changes include:
- Introduced `tun_generate_ue_ifname` and `tun_destroy` functions for better
TUN interface lifecycle management.
- Added support for creating and destroying UE-specific TUN interfaces in SDAP.
- Refactored `nr_pdcp_module_init` to remove TUN-related logic and moved it
to SDAP.
- Updated NAS and SDAP layers to handle PDU session-specific TUN interface
creation and configuration.
- Enhanced SDAP entity management to include TUN socket handling and thread
lifecycle.
- Updated NAS message handling to initialize default PDU session TUN
interfaces in NOS1 mode.
- Use a single SDAP thread function for gNB and UE
- Allow noS1 mode also in SA on gNB
These changes improve modularity by isolating TUN interface management within
the SDAP layer, aligning with the 3GPP architecture, and simplifying the PDCP
layer.

3GPP 38.331 release 16 specifies that If the field reportQuantity-r16 is present, UE shall ignore reportQuantity (without suffix).
reportQuantity-r16 configures SSB based SINR as the reporting quantity.
set do_SINR = 1; in gNB params part of the config file to enable SSB based SINR reporting instead of the default RSRP based.
Replaced `sprintf` with `snprintf` in gnb_config.c to enhance memory safety
by preventing potential buffer overflows. `sprintf` can cause buffer overflows
by not checking the destination buffer size. In contrast, `snprintf` allows
specifying a maximum buffer size, ensuring no overflow occurs by limiting
the number of characters written, including the null terminator.
- encode all SI containers the encoding function gets (it's not the
encoding function's job to enforce semantics)

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.
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
