Update based on !3645
Note: For some test configurations we still need to provide
ra_ResponseWindow, for more details, check commit message of

1. Refactor PDCCH PHY functions to take rxdataF of one OFDM symbol and
produce LLR for each search space. The modified functions take
rxdataF in a different format than that produced by nr_slot_fep(). So
for now a memcpy is used to change the array structure. Once
nr_slot_fep() is modified, this memcpy will no longer be needed and
will be removed.
2. Modify DCI functions to decode DCI in the last PDCCH symbol and
inidcate to MAC once.
3. Fix PDCCH monitoring for start symbol > 0.
4. Fix multiple PDCCH monitoring within slot.

1.Create new funtion nr_symbol_fep() to do OFDM demod of one symbol on
all antennas. This is called by nr_slot_fep() for now. In the
upcoming MR, this function will be called directly after reading
each OFDM symbol from the radio.
2.Removed redundant memory alignment. DFT function performs memory
alignment if the input memory is not aligned.
Fixes for T-Tracer to work with NR-UE
Fixes to align NR UE events with their definitions in T_messages.txt and
match the expected format in the tracer GUI parser.
Also fixes DL SNR to work in tracer GUI.
Support beam index in OAI 7.2 Fronthaul Interface
This branch supports beam index in OAI 7.2 Fronthaul Interface.
- For CP DL (PDSCH), nBeamIndex of the corresponding prbMapElm is set
when sending IQ data in oran_fh_if4p5_south_out. nBeamIndex of the
corresponding prbMapElm is set when sending IQ data in
oran_fh_if4p5_south_out.
- For CP UL (PUSCH and PRACH), nBeamIndex of the corresponding prbMapElm
is set in oran_fh_if4p5_south_out.
In addition, it fixes a couple of issues
- XRAN hardcodes nBeamIndex of PRACH to zero. Modify XRAN to support
setting of nBeamIndex of PRACH and update xran F release patch.
- Fix the bug in calculating fh_config->neAxc where num_beams_period is
multiplified twice
Testing methodology: Use Benetel O_RU for testing even though it does
not support beamforming. With successful registration and data transfer,
one could check the pcap on the fronthaul interface to see if CP packets
are with the right beam index.
Results:
1. Verified that CP-packets for SSB, DCI, PDSCH, PRACH, PDSCH, PUSCH,
CSI-RS and SRS are with the right beam index
2. Verified that there is no side-effect on Benetel O_RU. UE could
register properly.
3. Verified 4 SSB with ssb_PositionsInBurst_Bitmap = 85. Could see SSB
and PRACH with 4 different indices.
Handle CP UL packet at xran_fx_tx_send_slot() instead of
xran_fh_rx_read_slot(), as the latter would set this information too
late (on reception on samples, but it needs to be filled in the CP
packet prior to reception).
Initialize ru_info structure with beam information, and set beams on TX
direction. Initialize the number of antennas for both RX/TX in both
cases for completeness.
By configuring the Jenkins pythonExecutor to match the test machine, we can use
localhost as the node for running individual test cases. This change makes it
easy to move tests across machines, as the only adjustment needed is updating
the pythonExecutor in Jenkins.

1. Fix UE_PHY_PDSCH_IQ event
2. Fix UE_PHY_PDCCH_ENERGY event
3. Fix UE_PHY_PDSCH_ENERGY event
4. Fix UE_PHY_MEAS event
All fixes align NR UE events with their definitions in T_messages.txt and match the expected format in the tracer GUI parser.

CI: Upgrade Aerial setup to 25-2.1
The purpose of this MR is to upgrade the cuBB image in the Aerial setup to
release 25-2.1 and update the doc/Aerial_FAPI_Split_Tutorial.md accordingly.
CI: Upgrade HO setup to use an attenuator
The goal of this MR is to upgrade HO CI setup to include a digital attenuator
that will allow us to trigger handover by attenuating the signals on the DUs.
Doing this before using set_master_clock_rate() on the B200 seems to
invalidate synchronization setting.
[HW] USRP clock set to 1759836386.000000 sec
[...]
[HW] current pps at 3.286750, starting streaming at 4.286750
In other words, the current time setting was reset. With this change
now, we see
[HW] USRP clock set to 1759929873.000000 sec
[...]
[HW] current pps at 1759929873.000000, starting streaming at 1759929874.000000
This is because changing clock sources (I assume setting the master
clock rate impacts the clock) can result in changing the time. From the
documentation of [1]:
> Note: When changing clock sources, a previously set time will most
> likely be lost. It is recommended to set the time after changing the
> clock source. Otherwise, an unexpected time may line up with future PPS
> edges.

- Add band mismatch check in valid_du_in_neighbour_configs function
- Ensures neighbor cell band matches serving cell band
- Prevents invalid neighbor configurations for handover
The code only checked that Msg3 would be scheduled during UL, but in
some combinations, e.g., with DSUUU, the current slot can very well be
UL as well => we would schedule DCI in UL slot.
