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 ChannelDescription

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, see Downlink 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, see Downlink Physical Channels.
