Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitting device may obtain a demodulation reference signal (DMRS) for frequency range two (FR2) non-terrestrial network (NTN) communications, the DMRS having a DMRS sequence with a peak-to-average power ratio (PAPR) that satisfies a PAPR condition in a time domain. The transmitting device may transmit the DMRS to a receiving device in an NTN network associated with the FR2 NTN communications. Numerous other aspects are described.
