Remove the \file directive, as it is always superfluous because the
current file is implicit [1]:

Author names and e-mails are not relevant for us: it can always be

Eurecom code has been contributed and was under OAI PL v1.0/v1.1.
For the cpack package contact: put generic email address that is
independent of an individual and that will remain reachable.

Remove L1 dependence from NR band number
L1 band information relied on get_band function that couldn't provide an
unambiguous result. Also there is no SCF compliant parameter for L1 and
generally we don't really need that information in L1.
The MR also remove a RU section that used nr_band but was never really
accessed in NR.
Prevent the PNF from sending P7 messages after sending a STOP.indication
Upon stopping the PNF, when sending the STOP.indication to the VNF, set
pnf_p7->terminate to 1.
Add a check on the PNF P7 send functions to not send a message after
pnf_p7->terminate is set.
This prevents the PNF from sending SLOT.indications after stopping,
which sometimes was causing the VNF to process a SLOT.indication after
it had received the indication to STOP.
Also, this MR adds a sanity check on the VNF P7 message handler to
ignore any P7 messages it receives after having it's own terminate flag
set to 1
This MR closes issue #1045
semi-manual remove of not used #define commands
As i was upset to see all these #define with no code under, i made a
global pass to remove the obvious cases semi-manual remove of not used
bodies
manual script, then a lot of manual review
grep -IRs "#define" ../openair* ../common/* ../executables/ ../nfapi/ ../radio/ | \
fgrep -v '(' | fgrep -v '//' |awk '{print $2}' | egrep -v "#define *$n"| \
while read n ; do
grep -IRs $n ../openair* ../common/* ../executables/ ../nfapi/ ../radio/ | grep -v "#define *$n" | grep -q $n || echo $n;
done
will give a decent list of #define never used. Then, I think we should
keep lists of # define when it comes from standards, even if the code
doesn't use it right now
CORESET start multiple of 6 fix
According to the standard any CORESET (except CSET0) would always start
from the first common resource block index which is multiple of 6 in the
BWP. This was not taken into account in the code. The BWP switch CI test
is modified to test a BWP start not multiple of 6.
An exception is the case where rb-Offset-r16 parameter is set, but can't
be used at gNB for FAPI compatibility.
Closes: #1037
Make sure to apply Doppler and TA not directly when receiving the target cell ntn_config,
but apply Doppler just before the initial sync, and the TA after the initial sync when
we have tha actuel cell frame and slot numbers.
We need the ntn_config when reconfiguring the PHY layer for a new initial sync,
e.g. for calculating the DL Doppler frequency.
As a dedicated scheduled_response dl_config PDU it reaches the PHY layer too late,
as part of the phy_config.config_req it reaches the PHY layer in time with the
other configuration values.
When doing analogue beamforming, the beam ID for a pre-defined beam
table is passed directly to RU and there is no need to store the beam
table in PHY.
NR UE: calculate TA based on SIB19 information in NTN mode, if autonomous TA is not enabled
To achieve the goal, the hyper frame number (HFN) is introduced at the NR UE
PHY, MAC and RRC layers.
Besides this, we also implemented an orbit propagation to improve the accuracy
of N_UE_TA_adj, and a fix to keep the N_TA from RAR and MAC CE.
Fixes#981
Correctly copy nFAPI messages
All nFAPI message have copy helpers, so use that for "loading" nFAPI
messages into the L1. This also fixes a bug/error message
2. 0 no corresponding tx_data.request for dl_tti.request index 11, dropping
because the loop over DL_tti.request assumed that all messages are PDSCH
PDUs, when we can have others such as PDCCH, etc. In other words, when
looking up indices ("11" in the example above), we were checking also
inside other messages for SSB, PDCCH, etc, which is of course wrong.
That loop was an attempt to validate matching PDSCH PDUs with
TX_data.requests. This check is already done inside
phy_procedures_gNB_TX() through an assert, but this commit replaces with
the equivalent check previously inside nr_pnf_p7_get_msgs(). This is ok,
as the L1 cannot trust the scheduler (in monolithic) to provide the
correct information, either.

Implementation of STOP exchange
This implements the STOP.request/indication for all 3 transport mechanisms, the
VNF will send the STOP.request to the PNF, indicating it will disconnect, and
await a STOP.indication from the PNF
The WLS VNF is reworked to be able to start before the PNF, by calling call
rte_eal_init and rte_dev_probe to determine if dpdk has been initialized
properly, before calling rte_eal_init in the intended process when it is
appropriate to do so
Instead of trying to estimate N_UE_TA_adj with a second degree polynomial,
we introduce orbit propagation to calculate N_UE_TA_adj with higher accuracy.
When we receive the satellite ephemeris data consisting of the satellite position vector
and the satellite velocity vector, we calculate parameters for orbit propagation, assuming
a circular orbit in the plane created by the satellite position vector and the satellite
velocity vector. This is done in the function prepare_ue_sat_ta().
Every millisecond, we use these parameters together with the time since epoch to calculate
the satellite position on that orbit and from this the reound-trip-time between UE and the
satellite, what corresponds to N_UE_TA_adj. This is done in the function apply_ntn_timing_advance().
Reimplement nFAPI message exchange between L1 and L2 following the
changes in parent commit removing msgDataTx.
Avoid direct calls and use NR_IF_module fptrs to avoid linking problems.
allowing to remove some function definitions that are not needed.

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.
