Robert Schmidt c2d16eb8d5 Configure secondaryCellGroup: dedicated PUCCH, CSI, Preamble 
- Configure PUCCH Format 0 to be in separate RBs (each UE has dedicated
  resources)
- Configure RA preamble to be different per UE
- Configure CSI offset such that no two UEs have their report in the
  same frame

Thomas Schlichter b073ca48c3 gNB: improve TA accuracy 
The TA calculation takes the CIR peak position error and scales it according to 38.213 section 4.2.
Till now it was simply an integer division "timing_advance_update = sync_pos / bw_scaling".

E.g. in case of bandwidth_scaling == 16, the timing_advance_update was 0 for sync_pos between -15 and +15.
With this change, this range (and thus the UL timing error) will be reduced to -8 and +8.

Thomas Schlichter 5c6865fbc6 5G NR: simplify init_timeshift_rotation() 
Only Ncp1 is used, so get rid of the second timeshift_symbol_rotation array.
Also simplify the computation of "t0 * Tc * f".

Thomas Schlichter 942037beb3 5G NR: move CIR peak to 0 
The rotation compensating the shifted OFDM position _before_ the channel estimation makes the CIR peak move back to 0.
We have to take this into account on gNB side when calculating the timing advance command, and on UE side in the time adjustment.

Raghavendra Dinavahi 5934e8e4ee Changes to Downlink DMRS MASK calculation 
Procedure fill_dmrs_mask is modified.
	- PDSCH Mapping Type B is supported
	- Modified according to sections 5.1.6.2 of Spec 38.214
	- Single and double symbol DMRS are handled in Type A and Type B

Mapping type according to the time domain allocation from DCI should be used to get the values of DMRS config
For sending sib1 - DCI FORMAT 1_0 will be used with SI_RNTI, UE should perform these actions
according to sections 5.1.6.2 of Spec 38.214

Additional DMRS set to pos2 in case of msg2 reception, msg3 transmission.

Mapping type B is added to RRC reconfig.
	- nr_dlsim updated to test typeA and typeB. Verified the changes.
	- RFSIM Validation of PDSCH Mapping TypeB  by changing timedomainallocation in configuration files.
