Abstract[English]
There is disclosed an apparatus comprising: means for receiving a downlink, DL, demodulation reference signal, DMRS; means for receiving a modulation order, M, to be used for an uplink, UL, DMRS; means for generating the UL DMRS; and means for transmitting the generated UL DMRS, using the modulation order M. There is also disclosed an apparatus comprising: means for selecting a modulation order, M, for an uplink, UL, demodulation reference signal, DMRS, transmission; means for transmitting a downlink, DL, DMRS; means for transmitting the selected modulation order, M, in the DL; means for receiving a UL DMRS, modulated using the selected modulation order; and means for deriving digital post distortion, DPoD, coefficients using the received UL DMRS.[French]
L'invention divulgue un appareil comprenant : un moyen permettant de recevoir un signal de référence de démodulation (DMRS) de liaison descendante (DL) ; un moyen permettant de recevoir un ordre de modulation (M) à utiliser pour un DMRS de liaison montante (UL) ; un moyen permettant de générer le DMRS UL ; et un moyen permettant de transmettre le DMRS UL généré en utilisant l'ordre de modulation M. L'invention divulgue également un appareil comprenant : un moyen permettant de sélectionner un ordre de modulation (M) pour une transmission de signal de référence de démodulation (DMRS) de liaison montante (UL) ; un moyen permettant de transmettre un DMRS de liaison descendante (DL) ; un moyen permettant de transmettre l'ordre de modulation sélectionné (M) dans la DL ; un moyen permettant de recevoir un DMRS UL, modulé en utilisant l'ordre de modulation sélectionné ; et un moyen permettant d'obtenir des coefficients de post-distorsion numérique (DPoD) en utilisant le DMRS UL reçu.
