Avoid assert on non-implemented SM write callback
The asserts might be used to intentionally stop the running process.
Further, it might be an annoyance if it happen unintentionally. Just
print an error message instead.
Ue monitoring stats
- one commit to add UE mac stats similar to gNB one and remove a partial
implementation at phy level of some counters
- second commit only rename the two UE persisted HARQ tyepdef names for DL
and for UL (one was saying "UE" but not the direction and the second the
direction but not "UE")
The asserts might be used to intentionally stop the running process.
Further, it might be an annoyance if it happen unintentionally. Just
print an error message instead, and return to FlexRIC that nothing is to
be sent.
Fix a small bug with total_res in gNB PUSCH symbol processing
Replaced total_res with res_per_task when deciding whether to start a threadpool
task or not. This does not have big impact on the software as the
nr_pusch_symbol_processing will recheck ul_valid_re_per_slot anyway but it may
reduce the number of thread pool tasks created.
The queue for finished jobs of PUSCH channel estimation is only used inside
nr_pusch_channel_estimation(). Since initialization is fast, it can be
declared on the stack in the function where it is used.

Added support for NTN FDD FR1 bands 254, 255, 256 as specified in 3GPP
TS 38.101-5. Example Conf files added for band254 for 15Khz, 5Mhz and
30Khz, 10Mhz configurations. Tested NTN GEO configuration on band 254
using these conf files.
There seem to be randomly occurring deadlocks when running the UE in the
CI. MR !3091 should fix this. While waiting for this, apply a workaround
by increasing the number of worker pools in the UE to 12.
Since tag 2024.w45/commit f54ca5714e,
standalone mode/--sa is the default and does not exist. Correspondingly,
it has been removed from the documentation.
For users reading recent documentation, but running an older version of
OAI, there might be a mismatch in that --sa is necessary to run OAI, but
not given in the documentation. Provide explanatory text to make users
aware of this.
Test for init_RA
A testcase for init_RA function.
The testcase redefines the following functions as stubs:
- nr_mac_rrc_ra_ind
- nr_write_ce_ulsch_pdu
- mac_rlc_data_req
- lockGet_ul_config
- release_ul_config
- remove_ul_config_last_item
- nr_ue_configure_pucch
These stubs can be used to check init_RA behavior
NR UE trigger for re-establishment
The implementation in this MR triggers RRC re-establishment at the UE in case
of radio link failure either for out of sync messages from lower layers or in
case maximum number of RLC retransmissions is reached.

* verify re-establishment on CU: we ping the core from the UE; this
sends packets on DRB, and because the sequence number mismatches, will
trigger a reestablishment. We accept in the ping that a couple of
packets might be lost; after ping is over, reestablishment must be
done as well (else the ping will already fail).

Trigger deregistration only in SA mode
Upon press of ^C, the UE triggers a NAS deregistration. This does not work
in do-ra or phy-test modes, because there is no NAS. Therefore, in non-SA
modes, just stop the UE directly.
This can potentially improve the 5G RFsim CI test case, because together with
a high RFsim timeout, the chances of the last HARQ status line being without
retransmissions is much higher. If that does not help, we can further increase
the retx threshold.

fix BSR report malformed, add SHORT BSR when it can (instead of LONG BSR)
simplify the code and make the code more explicit, but the may structure
remain (nr_write_ce_ulsch_pdu interface is complex, merging it into the
called would make simpler and more interstandable code), fix some asserts
related to this part of code
Added support for NTN FDD FR1 bands 254, 255, 256 as specified in 3GPP TS 38.101-5

In some runs of a multi-UE deployment, we see segfaults because
cell_group->spCellConfig is NULL. We should not segfault in that case,
so check for spCellConfig.
When the UE list is full, the iterator will run through all
MAX_MOBILES_PER_GNB UEs. It expects that eventually the pointer is NULL,
which is not the case if we have MAX_MOBILES_PER_GNB (or it simply
depends on the following memory). So give one array entry more, to
ensure that the last one is NULL.
- add new data structures for antenna processing.
- create arrays that keep track of certain values (max_ch, noise_amp2, nest_count and delay) per each antenna. These values are processed in order to determine one final output.
- add time processing measurements for each antenna, and prints them in nr_ulsim.
- make num_antennas_per_thread configurable in nr_ulsim and the gNB config file.
