Abstract (en)
[origin: WO2020076656A1] Technology for a user equipment (UE) operable to generate a demodulation reference signal (DM-RS) having a reduced peak-to-average power ratio (PAPR) is disclosed. The UE can generate binary DM-RS sequence in a time domain. The UE can map the binary DM-RS sequence to a 5 pi/2 binary phase shift keying (BPSK) constellation to form a pi/2 BPSK modulated binary DM-RS sequence. The UE can perform Discrete Fourier Transform (DFT) spreading and Orthogonal Frequency Division Multiplexing (OFDM) symbol generation on the pi/2 BPSK modulated binary DM-RS sequence to produce the DM-RS having the reduced PAPR. The UE can encode the DM-RS having 10 the reduced PAPR for transmission to a Next Generation NodeB (gNB) on a physical uplink shared channel (PUSCH) or a physical uplink control channel (PUCCH).
