Merge remote-tracking branch 'origin/fix_ntn_leo' into integration_2025_w07 (!3194) 

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

### gNB
The main parameter to cope with the large NTN propagation delay is the cellSpecificKoffset.
This parameter is the scheduling offset used for the timing relationships that are modified for NTN (see TS 38.213).
The main parameters to cope with the large NTN propagation delay are cellSpecificKoffset, ta-Common, ta-CommonDrift and the ephemeris data (satellite position and velocity vectors).
The parameter `cellSpecificKoffset_r17` is the scheduling offset used for the timing relationships that are modified for NTN (see TS 38.213).
The unit of the field Koffset is number of slots for a given subcarrier spacing of 15 kHz.
This parameter can be provided to the gNB in the conf file as `cellSpecificKoffset_r17` in the section `servingCellConfigCommon`.
The parameter `ta-Common-r17` is used to provide the propagation delay between the reference point (at the gNB) and the satellite.
The granularity of ta-Common is 4.072 × 10^(-3) µs. Values are given in unit of corresponding granularity.
The parameter `ta-CommonDrift-r17` indicates the drift rate of the common TA.
The granularity of ta-CommonDrift is 0.2 × 10^(-3) µs/s. Values are given in unit of corresponding granularity.
The satellite position and velocity vartors are provided using the following parameters:
`positionX-r17`, `positionY-r17`, `positionZ-r17`:
X, Y, Z coordinate of satellite position state vector in ECEF. Unit is meter.
Step of 1.3 m. Actual value = field value * 1.3.
`velocityVX-r17`, `velocityVY-r17`, `velocityVZ-r17`:
X, Y, Z coordinate of satellite velocity state vector in ECEF. Unit is meter/second.
Step of 0.06 m/s. Actual value = field value * 0.06.
These parameters can be provided to the gNB in the conf file in the section `servingCellConfigCommon`:

### NR UE
At UE side, there are two main parameters to cope with the large NTN propagation delay, cellSpecificKoffset and ta-Common.
`cellSpecificKoffset` is the same as for gNB and can be provided to the UE via command line parameter `--ntn-koffset`.
`ta-Common` is a common timing advance and can be provided to the UE via command line parameter `--ntn-ta-common` in milliseconds.
At UE side, only few parameters have to be provided, as the UE receives most relevant parameters via SIB19 from the gNB.
But to calculate the UE specific TA, the UE position has to be provided in the `ue.conf` file.
Also the LEO channel model has to be configured, e.g. by using an `@include` statement, just like on the gNB side:
```
...
position0 = {
x = 0.0;
y = 0.0;
z = 6377900.0;
}
@include "channelmod_rfsimu_LEO_satellite.conf"
```
So an example NR UE command for FDD, 5MHz BW, 15 kHz SCS, transparent GEO satellite 5G NR NTN is this:
```
cd cmake_targets
sudo ./ran_build/build/nr-uesoftmodem --band 66 -C 2152680000 --CO -400000000 -r 25 --numerology 0 --ssb 48 --rfsim --rfsimulator.prop_delay 238.74 --ntn-koffset 478 --ntn-ta-common 477.48
sudo ./ran_build/build/nr-uesoftmodem -O ../targets/PROJECTS/GENERIC-NR-5GC/CONF/ue.conf --band 254 -C 2488400000 --CO -873500000 -r 25 --numerology 0 --ssb 60 --rfsim --rfsimulator.prop_delay 238.74
```
For LEO satellites a third parameter specifying the NTN propagation delay drift has ben added, ta-CommonDrift.
`ta-CommonDrift` provides the drift rate of the common timing advance and can be provided to the UE via command line parameter `--ntn-ta-commondrift` in microseconds per second.
For LEO satellite scenarios, the parameter `--ntn-initial-time-drift` must be provided via command line, as the UE needs this value to compensate for the time drift during initial sync, before SIB19 was received.
This parameter provides the drift rate of the complete DL timing (incl. feeder link and service link) in µs/s.
Also, to perform an autonomous TA update based on the DL drift, the boolean parameter `--autonomous-ta` should be added in case of a LEO satellite scenario.
So an example NR UE command for FDD, 5MHz BW, 15 kHz SCS, transparent LEO satellite 5G NR NTN is this:
```
cd cmake_targets
sudo ./ran_build/build/nr-uesoftmodem --band 66 -C 2152680000 --CO -400000000 -r 25 --numerology 0 --ssb 48 --rfsim --rfsimulator.prop_delay 20 --rfsimulator.options chanmod -O ../targets/PROJECTS/GENERIC-NR-5GC/CONF/channelmod_rfsimu_LEO_satellite.conf --time-sync-I 0.2 --ntn-koffset 40 --ntn-ta-common 37.74 --ntn-ta-commondrift -50 --autonomous-ta
