Downlink Physical Channels

NPBCH, NPDCCH, and NPDSCH symbol generation, decoding, and index generation

Physical channels correspond to sets of time-frequency resources that carry transport channel data and control information. LTE Toolbox™ functions support these narrowband physical channels:

Physical ChannelInformation Carried
Narrowband physical broadcast channel (NPBCH)NB-IoT master information block (MIB)
Narrowband physical downlink control channel (NPDCCH)Downlink control information (DCI)
Narrowband physical downlink shared channel (NPDSCH)Broadcast control channel (BCCH) and system information
