Title

(EN) LAYER SPECIFIC DMR PILOT DENSITY

(FR) DENSITÉ PILOTE DMR SPÉCIFIQUE À UNE COUCHE

Abstract

(EN) Methods, systems, and devices for wireless communications are described. The described techniques provide for a wireless device to communicate a multi-layer transmission using layer-specific demodulation reference signal (DMRS) density. For example, the wireless device may communicate a first portion of a transmission using a first spatial resource with a first set of DMRSs having a first DMRS density and communicate a second portion of the transmission using a second spatial resource with a second set of DMRSs having a second DMRS density different from the first DMRS density. In some examples, the first DMRS density may be less than the second DMRS density when the first spatial resource is associated with a higher channel quality compared to the second spatial resource, or vice versa.

(FR) Sont divulgués des procédés, des systèmes et des dispositifs destinés aux communications sans fil. Les techniques décrites permettent à un dispositif sans fil de communiquer une transmission multicouche à l'aide d'une densité de signal de référence de démodulation (DMRS) spécifique à une couche. Par exemple, le dispositif sans fil peut communiquer une première partie d'une transmission à l'aide d'une première ressource spatiale avec un premier ensemble de DMRS ayant une première densité DMRS et communiquer une seconde partie de la transmission à l'aide d'une seconde ressource spatiale avec un second ensemble de DMRS ayant une seconde densité DMRS différente de la première densité DMRS. Dans certains exemples, la première densité DMRS peut être inférieure à la seconde densité DMRS lorsque la première ressource spatiale est associée à une qualité de canal supérieure par rapport à la seconde ressource spatiale, ou vice versa.
