- UE context status enters RRC_NR_NSA_RECONFIGURED state, after the eNB receives an RRCConnectionReconfigurationComplete message including the
scg_ConfigResponseNR_r15 container.
- Use this state to avoid triggering sGNB Addition Request multiple times

changes for ulsim to get functionality back. simulation behaviour for PUSCH is not good (BLER waterfall is way too steep even if SNR threshold is ok). Note develop does more or less the same thing but SNR threshold is lower.

- replaced nr_slot_t with int as it was barely used in the code (also is defined after an lte struct)
- removed use of phy_frame_config_nr from the UE (another file was created in SCHED_NR_UE, still the
  gNB file is used in some tests file at UE side)

- Msg2 scheduler used for testing purposes was removed
- Now the UE tries to DCI 1_0 scrambled with RA_RNTI in the RA window
- If no RAPID is found within the RA window, instructs PHY to TX PRACH

- IP data were fetched and passed to MAC directly at the PHY layer
- random data was generated whenever there's no upcoming data.
- Therefore these functionalities are now moved to MAC and FAPI interfaces
- are used instead.

- ceiling computation num of segments (cod/dec)
- fixes demodulation
- initialisation CW for PDSCH RA
- memcpy dl_ch_estimates to pdsch_vars_ra (hotfix)
- correct N_RB for DCI 1_0 and RNTI_RA

- LDPC decoder does not support lower MCS, therefore MCS 9 has been selected
  for the Msg2 configuration.
- This is done only in do-ra mode, in order to prevent any fallout on the
  current the configuration used for the operation with the commercial UE
