Uplink Physical Channels

5G NR physical uplink shared channel (PUSCH), physical uplink control channel (PUCCH) formats 0, 1, 2, 3, and 4, and physical random access channel (PRACH)

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 uplink channels.

Physical ChannelDescription
PUSCH — Physical uplink shared channel

The PUSCH carries user data, radio resource control (RRC) signaling messages, and uplink control information (UCI).

PUCCH 0 — Physical uplink control channel format 0The PUCCH format 0 carries hybrid automatic repeat-request (HARQ) and scheduling requests. Format 0 transmits at most two bits, using one or two OFDM symbols.
PUCCH 1 — Physical uplink control channel format 1The PUCCH format 1 is the long duration counterpart of format 0, transmitting at most two bits and using 4 to 14 OFDM symbols.
PUCCH 2 — Physical uplink control channel format 2The PUCCH format 2 carries channel state information (CSI) and multi-bit HARQ. Format 2 transmits more than two bits and uses one or two OFDM symbols.
PUCCH 3 — Physical uplink control channel format 3The PUCCH format 3 is the long duration counterpart of format 2, transmitting more than two bits and using 4 to 14 OFDM symbols.
PUCCH 4 — Physical uplink control channel format 4The PUCCH format 4 is the same as format 3 with support to up to four users.
PRACH — Physical random access channelThe PRACH carries random access preambles used for initiation of random access procedures.

For an overview of the available uplink shared and control channel coding functionalities, see Uplink Transport Channels and Uplink Control Information, respectively.
