*Dedicated Coreset and searchSpace (--> put to #30 together with Coreset0/Css0)

*PUSCH resource allocation (with DMRS)

*Initial active DL BWP

*Dedicated active DL BWP

*Initial active UL BWP

*Dedicated active UL BWP

(6) PUSCH resource allocation (with DMRS)

struct NrDci00
{
	NrRnti rnti;
	int dciSlot;
	NrSubcarrierSpacing scsPdcch;
	NrSubcarrierSpacing scsPusch;
	NrPuschTimeAlloc timeAlloc;
	NrPuschFreqAllocType1 freqAlloc; 
	NrPuschFreqHopping fh;
};

struct NrDci01RaType0
{
	NrRnti rnti;
	int dciSlot;	//n
	int scsPdcch;	//u_PDCCH of active DL BWP
	int scsPusch;	//u_PUSCH of indicated UL BWP or active UL BWP
	int bwpIdAct;
	int bwpIdIndicated; 
	NrPuschTimeAlloc timeAlloc;
	NrPuschFreqAllocType0 freqAlloc; 
	int antPortsField;	//the ‘antenna port(s)’ field of DCI 0_1
	//RA type 0 doesn’t support transform precoding and frequency hopping
};

struct NrDci01RaType1
{
	NrRnti rnti;
	int dciSlot;	//n
	int scsPdcch;	//u_PDCCH of active DL BWP
	int scsPusch;	//u_PDSCH of indicated UL BWP or active UL BWP
	int bwpIdAct;
	int bwpIdIndicated; 
	NrPuschTimeAlloc timeAlloc;
	NrPuschFreqAllocType1 freqAlloc; 
	NrPuschFreqHopping fh;
	int antPortsField;	//the ‘antenna port(s)’ field of DCI 0_1
};

struct NrPuschTimeAlloc
{
	int timeAssignField;	//can be 0~15, the value of ‘Msg3 PUSCHTime domain resource assignment’ or ‘Time domain resource assignment’ field
	int mappingType;	//can be typeA or typeB
	int k2;	//K0, based on scs of PDSCH
	int sliv;	//can be 0~127
	int startingSymb;	//S of SLIV
	int symbLength;	//L of SLIV
};

enum NrPuschFreqHopping
{
	//{disabled, intra-slot, inter-slot}
}

enum NrPuschTransformPrecoding
{
	//{enabled, disabled}
}

struct NrDmrsPuschConfig
{
	NrDmrsType type;
	bool puschInDmrsSymb;
	int addPos;	//dmrs-additionalPosition, can be {pos0, pos1,po2, pos3}
	int maxLength;	//can be {len1, len2}
	int rank;	//can be 1~4
	//NrPtrsPuschConfig ptrs;
	std::vector<int> antPorts;	//=1000 for DCI 1_0
	int numCdmGroupsWoData;	//can be 1~3
	int frontLoadedSymbs;	//the number of symbols for front-loaded DMRS
};

struct NrPtrsPuschConfig
{
	//TODO
};

(7) Initial active DL BWP

struct NrInitialDlBwpCoreset0
{
	NrCoreset0 coreset0;
	NrCss0 css0;
	NrSib1PdschConfig sib1;
};

Assume coreset0/css0 applies to initialDownlinkBWP IE of SIB1 as well.

struct NrInitialDlBwpSib1
{
	NrBwpGeneric bwp;	//bwpId=0, this bwp should fully contain CORESET0
	NrCoreset0 coreset0;
	NrCss0 css0;
	NrType1PdschConfig msg2;	//RAR
	NrType1PdschCOnfig msg4;
};

struct NrBwpGeneric
{
	int id;	//bwp index, 0~3
	NrSubcarrierSpacing scs;
	NrCyclicPrefix cp;
	int loctionAndBw;	//can be 0~37949
	int startingRb;	//RB_start as specified by locationAndBw
	int numRb;	//L_RBs as specified by locationAndBw
};

(8) Dedicated active DL BWP

struct NrActDlBwp
{
	NrBwpGeneric bwp;	//bwpId=1
	NrPdcchConfig pdcch;
	NrType0PdschConfig type0Pdsch;
	NrType1PdschConfig type1Pdsch;
};

struct NrPdcchConfig
{
	NrCoreset coreset1;	//coresetId=1
	NrSearchSpace uss;	//ssId=1, type=USS, dciFormats=DCI01_DCI11
};

struct NrType0PdschConfig
{
	NrDci11RaType0 dci11RaType0;	//rnti=C-RNTI
	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
	NrPdschDmrsConfig dmrs;
};

struct NrType1PdschConfig
{
	NrDci10 dci10;	//rnti=RA-RNTI(Msg2/RAR) or TC-RNTI(Msg4)
	NrDci11RaType1 dci11RaType1;	//rnti=C-RNTI
	int aggFactor;	//can be {1,2,4,8}, equal to 1 for DCI 1_0 with CSS0, limited to a single layer transmission
	NrPdschDmrsConfig dmrs;
};

struct NrSib1PdschConfig
{
	NrDci10 dci10;	//rnti=SI-RNTI for SIB1
	int aggFactor;	// equal to 1 for DCI 1_0 with CSS0, limited to a single layer transmission
	NrPdschDmrsConfig dmrs;
};

(9) Initial active UL BWP

struct NrInitialUlBwpSib1
{
	NrBwpGeneric bwp;	//bwpId=0, same as NrInitialDlBwpSib1 for TDD
	NrPrachConfig prach;
	NrMsg3PuschConfig msg3Pusch;
	NrPucchConfig pucch;
};

Msg3 is scheduled by RAR UL grant (rv=0), and its retransmission is scheduled by DCI 0_0 with TC-RNTI.

Assume there is no Msg3 retransmission.

(10) Dedicated active UL BWP

struct NrActUlBwp
{
	NrBwpGeneric bwp;	//bwpId=1, same as NrActDlBwp for TDD
	NrPucchConfig pucch;
	NrType0PuschConfig type0Pusch; 
	NrType1PuschConfig type1Pusch;
	NrSrsConfig srs;
};

struct NrPucchConfig
{
	//TODO
};

struct NrType0PuschConfig
{
	NrDci01RaType0 dci01Type0;	//rnti=C-RNTI
	int rbgConfig;	//rbg-Size, can be {config1, config2}
	int rbgSize;	//the nominal size of RBG P
	int aggFactor;	//can be {1,2,4,8}, limited to a single layer transmission
	NrPuschDmrsConfig dmrs; 
};

struct NrType1PuschConfig
{
	NrDci00 dci00;	//rnti=TC-RNTI, msg3 PUSCH retransmission
	NrDci01RaType1 dci01Type1;	//rnti=C-RNTI
	int freqOffset;	//frequency offset of 2nd hop in case of intra-slot FH
	NrPuschTransformPercoding tp; 
	int aggFactor;	//can be {1,2,4,8}, limited to a single layer transmission
	NrPuschDmrsConfig dmrs;
};

For simplicity, aggFactor is fixed to 1, aka, multi-slots PUSCH is not supported.

struct NrMsg3PuschConfig
{
	NrRarUlGrant rarGrant;
	int freqOffset;	//frequency offset of 2nd hop in case of intra-slot FH
	NrPuschTransformPercoding tp; 
	int aggFactor;	// equal to 1 for Msg3
	NrPuschDmrsConfig dmrs;
};

struct NrSrsConfig
{
	//TODO
};
