High PAPR leads to inefficient Power Amplifier (PA) operation, requiring high back-off to avoid signal clipping and out-of-band emissions. 5G NR uses DFT-s-OFDM in the uplink to reduce PAPR for better coverage.
DFT-s-OFDM (SC-FDMA) has lower PAPR than CP-OFDM.
Lower PAPR allows the UE to transmit at higher power (better coverage).
