Title (EN) SIGNALING OF DEMODULATION REFERENCE SIGNAL CONFIGURATION FOR UPLINK SHORT TTI TRANSMISSIONS
(FR) SIGNALISATION DE CONFIGURATION DE SIGNAL DE RÉFÉRENCE DE DÉMODULATION POUR TRANSMISSIONS À TTI COURTS DE LIAISON MONTANTE
Abstract:
(EN) A method, wireless device and network node for multiplexing demodulation reference signals, DMRS, during short transmission time intervals, sTTIs. According to one aspect, a method includes generating an indication of an interleaved frequency division multiple access, IFDMA, subcarrier configuration for DMRS transmission. The method further includes transmitting to the wireless device (16) the indication of IFDMA subcarrier configuration.
(FR) La présente invention porte sur un procédé, un dispositif sans fil et un nœud de réseau conçus pour multiplexer des signaux de référence de démodulation (DMRS) pendant de courts intervalles de temps de transmission (sTTI). Selon un aspect, un procédé consiste à générer une indication d'une configuration de sous-porteuse d'accès multiple par répartition en fréquence entrelacée (IFDMA) pour une transmission DMRS. Le procédé consiste en outre à transmettre au dispositif sans fil (16) l'indication de la configuration de sous-porteuse IFDMA.
