TBConfig#
- class sionna.phy.nr.TBConfig(**kwargs)[source]#
Bases:
sionna.phy.nr.config.ConfigSets parameters related to the transport block encoding, as described in TS 38.214 [3GPPTS38214].
All configurable properties can be provided as keyword arguments during initialization or changed later.
The TBConfig is configured by selecting the modulation and coding scheme (MCS) tables and index.
Examples
from sionna.phy.nr import TBConfig tb_config = TBConfig(mcs_index=13) tb_config.mcs_table = 3 tb_config.channel_type = "PUSCH" tb_config.show()
The following tables provide an overview of the corresponding coderates and modulation orders.

Attributes
- property mcs_index: int#
Modulation and coding scheme (MCS) index (denoted as \(I_{MCS}\) in [3GPPTS38214]).
- property mcs_table: int#
Indicates which MCS table from [3GPPTS38214] to use. Starts with “1”.
- property n_id: int | None#
Data scrambling initialization \(n_\text{ID}\).
Data scrambling ID related to cell id and provided by higher layer. If None, the
PUSCHConfigwill automatically set \(n_\text{ID}=N_\text{ID}^{cell}\).
- property tb_scaling: float#
TB scaling factor for PDSCH as defined in [3GPPTS38214] Tab. 5.1.3.2-2.
