- Add to common/utils/nr/nr_common remove from NR_MAC_UE/nr_ue_procedures.c
- Adopt in asn1_msg.c for MeasurementReport: this solves the following assert:
Assertion (enc_rval.encoded > 0) failed!
In do_nrMeasurementReport_SA() /oai-ran/openair2/RRC/NR/MESSAGES/asn1_msg.c:898
ASN1 message encoding failed (MeasResultServMOList, 18446744073709551615)!
Motivation: unify RSRP-to-index mapping across layers and fix NR RRC MeasurementReport
encoding failures due to out-of-range values by reusing the validated mapping.
Note NR_RSRP-Range.c constraint:
{ APC_CONSTRAINED, 7, 7, 0, 127 } /* (0..127) */
- modify retrieve_ldpc_enc_op() to store encoded results in a packed format
- add timing measurements for T2 encoder
- add simde implementation for bit reversal
- Introduce new bit reversal implementation using simde_mm_gf2p8affine_epi64_epi8
instruction, based on https://wunkolo.github.io/post/2020/11/gf2p8affineqb-bit-reversal/.
This implementation requires GFNI and AVX512VL support on the target machine.
NR UE: consider the ratio of PUSCH EPRE to DMRS EPRE when calculating PUSCH
DMRS power scaling
When calculating DMRS scaling ratio, we should consider PUSCH EPRE to DMRS
EPRE according to TS 38.214 Table 6.2.2-1.

Long PRACH extends beyond a slot. Changes necessary to mark future slots
that may contain prach in ru, phy and mac functions.
In RU, the PRACH IDFT is done only after receiving last slot and marks
for L1 to start processing. The L1 processes at the last prach slot and
reports to MAC with the first slot index.
In MAC scheduler, the VRB for future slots are also marked as used.
PRACH scheduler is called in advance one frame minus num prach slots.
Added Support of 35Mhz,45Mhz,70Mhz Bandwidth
Added Support of 35Mhz,45Mhz,70Mhz Bandwidth for 30Khz Subcarrier
Spacing, Also added 35Mhz, 45Mhz bw for 15Khz Subcarrierspacing.
Referred Spec TS 38.101 v18.6.0 section 5.3.2, table 5.3.2-1
Changes to support multiple TDD patterns
- Updated the configuration changes for 2 Patterns
- Update the TDD table configuration for NFAPI
- Added the tdd bitmap for the period
- Adapted the bitmap for UL/DL for the multi TDD pattern
- Updated the RACH procedure for multi TDD pattern
- Updated DL and UL scheduler for multi TDD pattern
* the function is returning the index of the first full UL slot in tdd_slot_bitmap
or the first UL slot (including mixed) if the "mixed" flag is provided
* set_tdd_bmap_period, config_tdd_patterns: to configure TDD period, including bitmap, in the frame structure
* get_tdd_periodicity: to retrieve the periodicity in milliseconds for the given TDD pattern
* get_tdd_period_idx: to get the TDD period index based on pattern periodicities
* get_ul_slots_per_period: get the number of UL slots (including mixed with UL symbols) in period
* get_full_ul_slots_per_period: get the number of full UL slots in period
* get_dl_slots_per_period: get the number of DL slots (including mixed with DL symbols) in period
* get_full_dl_slots_per_period: get the number of full DL slots in period

Implement run-to-completion for processSlotTX. This is achieved by using a new
dynamic_barrier_t which allows to specify callback after the first join has been
made.
Added support for NTN FDD FR1 bands 254, 255, 256 as specified in 3GPP TS 38.101-5
Conf files added for 15Khz, 5Mhz and 30Khz, 10Mhz configurations added for these bands
Pass consistently the NR_timer_t object through a pointer. Since we have
to modify all occurrences of is_nr_timer_active(), we use that occasion
and rename that function to nr_timer_is_active() to make it consistent
with all other functions, starting with nr_timer.
A new phy scope based on ImGui and ImPlot. This scope uses a different concurrency model than previous
scopes.
The PHY thread writing the data first checks if the data is ready to be written. If its not, nothing is copied.
The GUI thread reads data if available and marks it ready to write. This makes sure that the PHY threads are not
busy copying data that would never be displayed.
Some of the scopes also have a freeze functionality that further limit the amount of data that needs to be copied
from PHY threads. If a scope is "frozen" it still allows the user to explore the data using plots zoom/pan functions
but doesn't cause PHY threads to perform extra writes on the displayed data.
A compile option was added to enable/disable the scope. Use cmake -DENABLE_IMSCOPE=ON to enable the scope.
Update CXX standard to 17; it is required by some libraries (e.g., dear imgui). The oldest gcc version in
use by a distribution supported is Ubuntu 20, which has gcc 9.4 with c++17 support.
