Abstract
A service device (e.g., a user equipment (UE), a new radio NB (gNB), or other network component or network management component) can process or generate a Downlink Control Information (DCI) that schedules a Physical Uplink Shared Channel (PUSCH) transmission in a PUSCH. The PUSCH transmission can be generated based on a Demodulation Reference Signal (DMRS) according to a Discrete Fourier Transform (DFT) spread Orthogonal Frequency Division Multiplexing (DFT-s-OFDM) waveform in uplink. A sequence of the DMRS can be generated based on a Gold sequence and a Pi/2 Binary Phase-Shift Keying (BPSK) modulation.
