OFDM (Orthogonal Frequency Division Multiplexing) is the modulation technique used in 5G NR. It divides the available bandwidth into a large number of narrow subcarriers, which are modulated independently.

The maximum number of subcarriers that can be used in 5G NR is 1024.

Polar codes are the coding scheme used in 5G NR. They are a type of channel code that can achieve the capacity of a channel with low decoding complexity.

The maximum code rate that can be achieved with polar codes is 1.

The minimum block length that can be used with polar codes is 4.

QPSK 1/2 is the MCS used for the control channel in 5G NR.

16QAM 3/4 is the MCS used for the data channel in 5G NR.

The maximum data rate that can be achieved with 16QAM 3/4 is 4 Gbps.

QPSK 3/4 is the MCS used for the uplink channel in 5G NR.

16QAM 3/4 is the MCS used for the downlink channel in 5G NR.

The maximum data rate that can be achieved with 16QAM 3/4 in the uplink channel is 2 Gbps.

The maximum data rate that can be achieved with 16QAM 3/4 in the downlink channel is 4 Gbps.

16QAM 3/4 is the MCS used for the MIMO channel in 5G NR.

The maximum data rate that can be achieved with 16QAM 3/4 in the MIMO channel is 8 Gbps.

16QAM 3/4 is the MCS used for the beamforming channel in 5G NR.

The maximum data rate that can be achieved with 16QAM 3/4 in the beamforming channel is 16 Gbps.
