Title
(EN) FACILITATION OF REDUCTION OF PEAK TO AVERAGE POWER RATIO FOR 5G OR OTHER NEXT GENERATION NETWORK

Abstract
(EN)
Because the number of transmitted layers can vary dynamically, the number of transmitted demodulation reference signals (DM-RS) can also vary. However, because the network node can know the number of ports, transmitted layers, or the rank, the network node can utilize the number as part of the scheduling information via a downlink or an uplink control channel. Therefore, the DMRS sequence generation can modified such that it depends on the number of ports, transmitted layers, or the rank, thereby generating a different random sequence for different ports.
(FR)
Étant donné que le nombre de couches transmises peut varier dynamiquement, le nombre de signaux de référence de démodulation (DM-RS) émis peut également varier. Cependant, étant donné que le nœud de réseau peut connaître le nombre de ports, de couches transmises ou le rang, le nœud de réseau peut utiliser le nombre en tant que partie des informations de planification par l'intermédiaire d'un canal de commande de liaison descendante ou de liaison montante. Ainsi, la génération de séquence DMRS peut être modifiée de telle sorte qu'elle dépende du nombre de ports, de couches transmises ou du rang, ce qui permet de générer une séquence aléatoire différente pour différents ports.
