Field Documentation

bg

uint8_t PdschPerTbParams::bg

base graph per TB; options are 1 or 2

cinit

uint32_t PdschPerTbParams::cinit

used to generate scrambling sequence; seed2 arg. of gold32

F

uint32_t PdschPerTbParams::F

filler bits

G

uint32_t PdschPerTbParams::G

number of rate-matched bits available for TB transmission without accounting punctured REs due to CSI-RS (max_G)

K

uint32_t PdschPerTbParams::K

non punctured systematic bits

max_REs

uint32_t PdschPerTbParams::max_REs

number of REs for TB transmission without accounting punctured REs due to CSI-RS. It's G /(Qm * Nl)

N

uint32_t PdschPerTbParams::N

bits in code block per TB

Ncb

uint32_t PdschPerTbParams::Ncb

same as N for now

Nl

uint8_t PdschPerTbParams::Nl

number of transmission layers per TB; [1, MAX_DL_LAYERS_PER_TB] in DL

num_CBs

uint32_t PdschPerTbParams::num_CBs

number of code blocks (CBs) per TB

Qm

uint8_t PdschPerTbParams::Qm

modulation order per TB: [2, 4, 6, 8]

rv

uint8_t PdschPerTbParams::rv

redundancy version per TB; [0, 3]

Zc

uint32_t PdschPerTbParams::Zc

lifting factor per TB
