A second thread message is created for L1 tx processing and pushed into the threaPool. The message contain the nfapi rel15 PDUs for SSB, PDCCH and PDSCH. The memory of these PDUs are reused for subsequent slots. Need to fix the nfapi mode VNF PNF implementation to adapt to this memory scheme.

- the band is coming from the SI, therefore a function to get the band is not necessary - this solves also the limitations of the get_band algorithm with the NR bands overlapping in the NR operating bands table (e.g. band 78 and band 48)
-
cig authored
- adapted the get_band function: the algorithm is now taking into account also the UL frequency in order to fetch the proper band (this was failing before as some NR bands have the same DL band, e.g. band 65 and 66) - added new bands to the NR table as per TS 38.101 V16.4.0 (2020) - made the from_nrarfcn function compatible with UL FDD (this function, used for both DL and UL was previously working with TDD only as it did not compute properly the frequency for the UL FDD, throwing asserts) - introduced common functions to get the NR table idx and the duplex mode, removing repeated code in the process - removed the unused function to get the uldl offset - improved some logging - other minor fixes to the relevant code

adding beamforming support to FAPI: MAC fills ssb_beam_id_list in ssb config. PHY uses this info to fill new beam_id field. This is further copied to RU and applied there. Nothing is tested so far.

FEATURE STATEMENT: - Introduce linear phase error noise model in Uplink at UE - Perform common phase error (CPE) estimation and compensation at gNB SOLUTION: - A linear phase shift model is introduced in simulation. - PTRS symbols are used to perform estimation of CPE from DMRS compensated signal - The estimated values are interpolated in time domain and signal is compensated for the CPE. - PTRS processing is done in Frequency Domain for each symbol in a slot and LLR's are calculated for each symbol accordingly. IMPLEMENTATION: * sim.h/channle_sim.c - Linear Phase Noise Generation model definition. * nr_ul_channel_estimation.c/nr_ul_estimation.h - CPE estimation from PTRS and DMRS compensated signal. * nr_dmrs_rx.c/nr_refsig.h - Regenerate PTRS symbols at gNB. * nr_ulsch_demodulation.c - Removed old PTRS processing code and move to a common PTRS processing function * defs_gNB.h/init.c - New PTRS variables definition and initialization * nr_ulsch_ue.c - Corrected PTRS parameter to get new PTRS symbols for each OFDM symbol TESTING * ulsim.c - Added Phase noise, Enable PTRS signal and verified the output. VERIFICATION - The LLR are rotated back with estimated CPE and no error is observed in scrambling/decoding
