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 BG was set to its default for rounds > 0. This is now fixed by adding it to harq structure. Also a fix for wrong I_lbrm set in dlsch decoding.

- Most DL code is reused for Ul also to reduce code duplication - Common CPE calculation function is used for error estimation - Common slot processing function is used for inter/extrapolation - Removed old implementation dedicated to UL

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
