Downlink Physical Channels

5G NR physical broadcast channel (PBCH), physical downlink shared channel (PDSCH), and physical downlink control channel (PDCCH)

Physical channels correspond to a set of time-frequency resources used for transmission of particular transport channel data, control information, or indicator information. Each transport channel data, control information, and indicator information is mapped to its corresponding physical channel. 5G Toolbox™ supports the following physical downlink channels.

Physical ChannelDescription

PBCH — Physical broadcast channel

The PBCH carries encoded system information required by the user equipment (UE) to access the network. For an overview of the available broadcast channel coding functionalities, see Downlink Transport Channels.

PDSCH — Physical downlink shared channel

The PDSCH carries encoded user data and paging information to the UE. For an overview of the available downlink shared channel coding functionalities, see Downlink Transport Channels.

PDCCH — Physical downlink control channel

The PDCCH conveys encoded control information and scheduling decisions for PDSCH reception. For an overview of the available downlink control channel coding functionalities, see Downlink Control Information.
