Guido Casati 0b873bb620 Time Alignment procedure with time adjustment as per TS 38.213 section 4.2 
- UE processing capability 1
- Setting the TA update to be applied after the reception of the TA command
- Durations of N1 and N2 symbols corresponding to PDSCH and PUSCH are
  computed according to sections 5.3 and 6.4 of TS 38.214
- Introduced tables 5.3-1, 5.3-2, 6.4-1, 6.4-2 from TS 38.214

Guido Casati c6855cb8d2 Maintenance of Uplink Time Alignment. Introduced control on TA transmission and TA update application. 
- ta_timer at gNB side to control the transmission of TA to the UE. This is now happening every 20 slots.
- when the timer resets gNB is now transmitting the TA whether it is zero or not.
- introduced struct NR_UL_TIME_ALIGNMENT_t to handle configuration of time alignment related parameters.
- UE PHY RX: is now triggered through a flag when to store the TA command, the frame and slot
  when the application should occur.
- UE PHY TX: when the tx frame and slot match the time alignment configuration, it process the TA command and applies the
  TA update

Thomas Schlichter ef3be74025 Fix channel estimation for 3/4 sampling 
In 3/4 sampling mode, the OFDM symbol size is _not_ a power of two (e.g. 1536 instead of 2048).
In this case it is _not_ OK to calculate the modulus using a binary AND, it _must_ use either the actul modulus operator (%) using an integer division,
or a _correct_ if statement or tertianary operator like this:

re_offset = (re_offset + 4 >= ue->frame_parms.ofdm_symbol_size) ? (re_offset + 4 - ue->frame_parms.ofdm_symbol_size) : (re_offset + 4);

But of course using the actual modulus operator is much more readable and surely not much slower:

re_offset = (re_offset + 4) % ue->frame_parms.ofdm_symbol_size;
