Low peak-to-average-power ratio (PAPR) transmissions significantly improve the cell coverage as they enable high power transmissions without saturating the power amplifier. A new modulation scheme, namely, pi/2-BPSK was introduced in the Rel-15 3GPP 5G NR specifications to support low PAPR transmissions using the DFT-spread-OFDM waveform in the uplink transmissions. To enable data demodulation using this modulation scheme, Zadoff-Chu sequences are used as reference signals. However, the PAPR of Zadoff-Chu sequences is higher when compared to the pi/2-BPSK data. Therefore, even though the data transmissions have low PAPR, the high PAPR of the reference signal limits the cell coverage in the uplink of Rel-15 3GPP 5G NR design. In this paper we propose a transceiver design which minimizes the PAPR of the reference signals to avoid the aforementioned issues. We show via simulations that the proposed architecture results in more than 2 dB PAPR reduction when compared to the existing design. In addition, when multiple stream transmission is supported, we show that PAPR of the reference signal transmission remains the same for any stream (also referred to as baseband antenna port in 3GPP terminology) when the proposed transceiver design is employed, which is not the case for the current 3GPP 5G NR design
