Title
(EN) DEMODULATION REFERENCE SIGNALING IN LTE/NR COEXISTENCE
(FR) SIGNALISATION DE RÉFÉRENCE DE DÉMODULATION EN COEXISTENCE LTE/NR
Abstract
(EN)
There is disclosed a method of operating a network node (100) in a radio access network, the method comprising transmitting signaling in a transmission timing structure, the signaling comprising demodulation reference signaling (DMRS), wherein the DMRS is transmitted on symbols of the transmission timing structure based on a DMRS pattern, the DMRS pattern being based on a pattern configuration indication set. The disclosure also pertains to related methods and devices.

L'invention concerne un procédé de fonctionnement d'un nœud de réseau (100) dans un réseau d'accès radio, le procédé comprenant la transmission d'une signalisation dans une structure de cadencement de transmission, la signalisation comprenant une signalisation de référence de démodulation (DMRS), la DMRS étant transmise sur des symboles de la structure de cadencement de transmission sur la base d'un motif DMRS, le motif DMRS étant basé sur un ensemble d'indications de configuration de motif. L'invention concerne également des procédés et des dispositifs associés.
