Title (EN) SIGNALING OF DMRS AND SPATIAL MULTIPLEXING CONFIGURATION FOR UPLINK SHORT TTI TRANSMISSIONS
(FR) SIGNALISATION DE DMRS ET CONFIGURATION DE MULTIPLEXAGE SPATIAL PERMETTANT DES TRANSMISSIONS À TTI COURTS DE LIAISON MONTANTE
Abstract:
(EN) According to one aspect of the disclosure, a wireless device for Interleaved Frequency Division Multiplexing (IFDMA) based reference signal (RS) multiplexing for short Physical Uplink Shared Channel (sPUSCH) transmissions is provided. The 5 wireless device is configured to use a frequency allocation that partially overlaps with a frequency allocation of another entity. The wireless device further configured to: receive a plurality of reference signal (RS) configuration bits, process the plurality of RS configuration bits based on a number of spatial layers assigned to the wireless device, determine an RS configuration for sPUSCH transmission based on the 10 processing of the plurality of RS configuration bits, and transmit an RS on the sPUSCH based on the determined RS configuration.
(FR) Un aspect de l'invention concerne un dispositif sans fil destiné à un multiplexage d'un signal de référence (RS) sur la base d'un multiplexage par répartition de fréquence entrelacée (IFDMA) permettant des transmissions d'un canal physique court partagé de liaison montante (sPUSCH). Le dispositif sans fil est configuré de manière à utiliser une attribution de fréquence qui chevauche partiellement une attribution de fréquence d'une autre entité. Le dispositif sans fil est en outre configuré de manière à : recevoir une pluralité de bits de configuration de signal de référence (RS); traiter la pluralité de bits de configuration de RS sur la base d'un nombre de couches spatiales attribuées au dispositif sans fil; déterminer une configuration de RS permettant une transmission de sPUSCH sur la base du traitement de la pluralité de bits de configuration de RS; et transmettre un RS sur le sPUSCH sur la base de la configuration de RS déterminée.
