10/23~10/28完成：
*PT-RS for PDSCH (<-- should be put together with #6-PDSCH resource allocation)
*PT-RS for PUSCH (<-- should be put together with #7-PUSCH resource allocation)
*SRS configuration
*PRACH configuration
*PUCCH configuration
Notes:
a), Remaining part:
*CSI-RS configuration
b), Coding can begin soon since all essential parts are ready! Although Data_Structures are illustrated in C++, actual implementation will use Python based on the NG Toolset framework.
(6.1) PDSCH resource allocation, part 2----PTRS for PDSCH
struct NrPtrsPdschConfig
{
int timeDensity; // the LPTRS can be 1/2/4,
int freqDensity; //the KPTRS, can be 2/4
int reOffset; // the resourceElementOffset, can be 0/1/2/3
int dmrsPort; // For simplicity, assume PTRS for PUSCH use the lowest index of DMRS antenna ports of CW0 in both one CW and two CWs scenarios.
};
In 'Dedicated active DL BWP' part, we introduce NrDedicatedPdschConfig：
struct NrDedicatedPdschConfig
{
int aggFactor; //can be {1,2,4,8}, limited to a single layer transmission
int rbgConfig; //rbg-Size, can be {config1, config2}
int rbgSize; //the nominal size of RBG P
};
（7.1） PUSCH resource allocation，part 2-------PTRS for PUSCH
When transform precoding is enabled for PUSCH, use NrPtrsPuschTpConfig; otherwise, use NrPtrsPuschConfig.
struct NrPtrsPuschConfig
{
int timeDensity; //can be 1/2/4
int freqDensity; //can be 2/4
int reOffset; //can be 0/1/2/3
int maxNumPorts; //can be 1/2
std::map<int, std::vector<int> > ptrsDmrsMapping; //[PTRS port, list of DMRS port(s)], and PTRS port = 0/1
};
struct NrPtrsPuschTpConfig
{
int timeDensity; //can be 1/2
int numGroups; //can be 2/4/8 as specified in 38.214 Table 6.2.3.2-1
int samplesPerGroup; //can be 2/4 as specified in 38.214 Table 6.2.3.2-1
std::map<int, std::vector<int> > ptrsDmrsMapping; //[PTRS port, list of DMRS port(s)] and PTRS port = 0
};
Further CB/nonCB PUSCH settings are included in NrDedicatedPuschConfig.
In 'Dedicated active UL BWP' part, we introduce NrDedicatedPuschConfig:
struct NrDedicatedPuschConfig
{
NrPuschTxConfig txConfig;
NrPuschCodebookSubset cbSubset;
int cbMaxRank; //can be 1~4
int nonCbMaxLayers; //can be 1~4, the Lmax in 38.212 Table 7.3.1.1.2-28~ Table 7.3.1.1.2-31
int aggFactor; //can be {1,2,4,8}, limited to a single layer transmission
int freqOffset; //frequency offset of 2nd hop in case of intra-slot FH
NrPuschTransformPercoding tp;
int rbgConfig; //rbg-Size, can be {config1, config2}
int rbgSize; //the nominal size of RBG P
};
enum NrPuschTxConfig
{
//{codebook, nonCodebook}
}
enum NrPuschCodebookSubset
{
//{ fullyAndPartialAndNonCoherent, partialAndNonCoherent, nonCoherent}
};
we also updated NrDmrsPuschConfig to distinguish CB PUSCH and NonCB PUSCH：
(11) SRS configuration
struct NrSrsConfig
{
NrSrsResourceSet cbSrsSet;
NrSrsResourceSet nonCbSrsSet;
};
struct NrSrsResourceSet
{

NrSrsResourceType type; //only periodic is supported!
NrSrsUsage usage; //only codebook/nonCodebook are supported!
};
enum NrSrsResourceType
{
//{aperiodic, semi-persistent, periodic}
}
enum NrSrsUsage
{
//{beamManagement, codebook, nonCodebook, antennaSwitching}
}
struct NrSrsResource
{
int id; //can be 0~63

}
struct NrPucchFormatConfig
{

bool interSlotFreqHop; //only applicable to format 1/3/4
bool additionalDmrs; //only applicable to format 3/4

int id;
int resId; //the id of NrPucchResource
NrSrPeriodicity period; //in slots
int offset; //in slots, can be [0, period-1], =0 for period={sym2, sym6or7, sl1}

int msg1Fdm; //can be {1, 2, 4, 8}
};
struct NrPrachTimeAlloc
{

std::vector<int> y;
std::vector<int> subfsFr1OrSlotsFr2;
int startingSymb;
int nRaTime; //the prach occasion index in time domain within a prach slot
int raDuration; //prach duration
int nRaSlots; //the number of prach slots within a subframe for FR1, or the number of prach slots within a 60khz slot for FR2
int numGap; //the N_Gap as specified in 38.213 8.1; numGap = 0 for 1.25k/5k and = 2 otherwise; and numGap = 0 for B4
};
struct NrPrachFreqAlloc
