The physical channels defined in the downlink are:

- the Physical Downlink Shared Channel (PDSCH),

- the Physical Downlink Control Channel (PDCCH),

- the Physical Broadcast Channel (PBCH),

The physical channels defined in the uplink are:

- the Physical Random Access Channel (PRACH),

- the Physical Uplink Shared Channel (PUSCH),

- and the Physical Uplink Control Channel (PUCCH).

In addition, signals are defined as reference signals, primary and secondary synchronization signals.

The modulation schemes supported are

- in the downlink, QPSK, 16QAM, 64QAM, and 256QAM,

- in the uplink, QPSK, 16QAM, 64QAM and 256QAM for OFDM with a CP and π/2-BPSK, QPSK, 16QAM, 64QAM and 256QAM for DFT-s-OFDM with a CP
