Procedures to determine PDCCH candidate of CSS0/CORESET0:

1, CCE-to-REG mapping procedure

Note1: For 'contents of regBundles/cces', horizontal is freq-domain and vertical is time-domain.

#for simplicity, assume SSB index is randomly selected!

3, Set of CCEs w.r.t. CSS0/CORESET0 with certain aggregation level and certain PDCCH candidate

scaleTd = self.baseScsTd // self.nrMibCommonScs

            firstSymbInBaseScsTd = (nc * self.nrSymbPerSlotNormCp + firstSymb) * scaleTd
            cceSet = [pdcchCandidate * self.nrCss0AggLevel + k for k in range(self.nrCss0AggLevel)]
            for i in range(self.coreset0Cces.shape[0]):
                for j in range(self.coreset0Cces.shape[1]):
                    if self.coreset0Cces[i, j] in cceSet:
                        if self.nrDuplexMode == 'TDD':
                            self.gridNrTdd[dn2][coreset0FirstSc+i*self.nrScPerPrb*scaleFd:coreset0FirstSc+(i+1)*self.nrScPerPrb*scaleFd, firstSymbInBaseScsTd+j*scaleTd:firstSymbInBaseScsTd+(j+1)*scaleTd] = NrResType.NR_RES_PDCCH.value
                        else:
