Abstract[English]
Methods and apparatus related to pulse shaped and overlapped reference signals are disclosed. Signaling that indicates information associated with a length of a base sequence and a length of a cyclic rotation is communicated between a first communication device and a second communication device in a wireless communication network. A DMRS is also communicated in the wireless communication network. The DMRS comprises a DMRS sequence of a target length, and the DMRS sequence comprises the base sequence cyclically rotated by the length of the cyclic rotation. Cyclic extension is also applied a base sequence in some embodiments.[French]
L'invention concerne des procédés et un appareil associés à des signaux de référence en forme d'impulsions et à chevauchement. Une signalisation qui indique des informations associées à une longueur d'une séquence de base et une longueur d'une rotation cyclique sont communiquées entre un premier dispositif de communication et un second dispositif de communication dans un réseau de communication sans fil. Un DMRS est également communiqué dans le réseau de communication sans fil. Le DMRS comprend une séquence DMRS d'une longueur cible, et la séquence DMRS comprend la séquence de base tournée cycliquement par la longueur de la rotation cyclique. Une extension cyclique est également appliquée à une séquence de base dans certains modes de réalisation.
