Field Documentation

◆ bundle_size

uint32_t PdcchParams::bundle_size

bundle size for PDCCH. It is in REGs. Can be 2, 3, or 6.

◆ coreset_map

uint64_t PdcchParams::coreset_map

Derived. Used as bitmask. Shifted version of freq_domain_resource

◆ coreset_type

uint32_t PdcchParams::coreset_type

Coreset type: 0 or 1

◆ freq_domain_resource

uint64_t PdcchParams::freq_domain_resource

Bitmask. Used to compute coreset_map, n_CCE, rb_coreset

◆ interleaved

uint32_t PdcchParams::interleaved

1 for interleaved mode, 0 otherwise

◆ interleaver_size

uint32_t PdcchParams::interleaver_size

Interleaving happens at the bundle granularity. Can be 2, 3, or 6.

◆ n_CCE

uint32_t PdcchParams::n_CCE

Derived. It is the number of set bits in coreset_map (or freq_domain_resource) multiplied by n_sym

◆ n_f

uint32_t PdcchParams::n_f

number of subcarriers in full BW

◆ n_sym

uint32_t PdcchParams::n_sym

number of PDCCH OFDM symbols (1-3)

◆ num_dl_dci

uint32_t PdcchParams::num_dl_dci

DCIs included in this CORESET

◆ rb_coreset

uint32_t PdcchParams::rb_coreset

Derived. Indicates the number of bits in coreset_map to be considered. It is # RBs divided by 6.

◆ shift_index

uint32_t PdcchParams::shift_index

shift index

◆ slot_number

uint32_t PdcchParams::slot_number

slot number

◆ start_rb

uint32_t PdcchParams::start_rb

starting RB

◆ start_sym

uint32_t PdcchParams::start_sym

starting OFDM symbol number
