Downlink Transport Channels

5G NR broadcast channel (BCH) and downlink shared channel (DL-SCH)

Use transport channels to encode and transmit transport blocks with specific characteristics. 5G Toolbox™ supports the following downlink transport channels.

Transport Channel	Description
BCH — Broadcast channel	The BCH encodes system information required by the user equipment (UE) to access the network. The encoded information is mapped to a physical broadcast channel (PBCH). For an overview of the available PBCH functionalities, seeDownlink Physical Channels.
DL-SCH — Downlink shared channel	The DL-SCH encodes user data and paging information. The encoded data is mapped to a physical downlink shared channel (PDSCH). For an overview of the available PDSCH functionalities, seeDownlink Physical Channels.

Functions

Broadcast Channel

`nrBCH`	Broadcast channel (BCH) encoding
`nrBCHDecode`	Broadcast channel (BCH) decoding

Downlink Shared Channel

`nrDLSCH`	Apply DL-SCH encoder processing chain
`nrDLSCHDecoder`	Apply DL-SCH decoder processing chain
`nrDLSCHInfo`	Get downlink shared channel (DL-SCH) information
