Sakthivel Velumani 66323e0b1d BG selection bug fix 
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.

Parminder Singh c9523b88a7 Updated UL ptrs processing wrt DL 
- 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

Florian Kaltenberger 60062cecfb 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. 2020-10-19 13:36:00 +02:00

Parminder Singh b288eafd1e Common Phase error estimation and compensation in uplink. 
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
