Raghavendra Dinavahi 4b51859b88 Enabling configuration files read for SL-Preconfig 
- for example when running nr-uesoftmodem with sidelink
	  use "-O ../../../targets/PROJECTS/NR-SIDELINK/CONF/sidelink_preconfig_1rxpool_1txpool.conf"

Raghavendra Dinavahi 5edee9b546 Mapping type A enabled in PUSCH dmrs mask calculation 
- Procedure get_l_prime is modified
	- Single and double symbol DMRS are handled in Type A and Type B

Raghavendra Dinavahi f3be3daa32 pusch_proc_threads=8 added to configuration files 2021-04-23 10:33:56 +02:00
Raghavendra Dinavahi fc1a7f7b8c Adjusting LocationBandwidth of initial BWP1 in configuration files. 
LocationandBandwidth adjusted according to the location of SSB and Controlresourceset 0
For example for 106RBs configuration files -
	- AbsoluteFrequencySSB = 641032 = RB43 (1032/24) - points to Subcarrier 0 of RB10 of SSB block
	- Hence SSB is located from RB33-RB53
	- Coresetzero sent in MIB is 0 which means offset 0, RBsize 24 from Start of SSB according to table 13.4 in Spec 38.213
	- InitialBWP should start from RB 33 (offset is 0 from SSB) and should be a size of minimum 24 RBs.
	- SLIV = 275 * (24-1) + 33 = 6358
Controlresourceset value wrongly configured to 12 , changed to 0 as sent in MIB.

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.
