Zusammenfassung:Technology for a Next Generation NodeB (gNB) operable to generate a downlink reference signal having a reduced peak-to-average power ratio (PAPR) is disclosed. The gNB can map complex pseudo noise (PN) sequence symbols to one or more codedivision- multiplexed (CDM)-Groups. The gNB can perform, on each CDM-Group of the one or more CDM-Groups, a CDM-Group specific linear non-linear operation on the complex PN sequence symbols mapped to the one or more CDM-Groups, to generate the downlink reference signal having the reduced PAPR. The gNB can encode, at the gNB, the downlink reference signal having the reduced PAPR for transmission to a user equipment (UE).
