Title (EN) TRANSMISSION RANK AND PRECODER SIGNALING IN UPLINK NON-CODEBOOK BASED TRANSMISSION
(FR) SIGNALISATION DE RANG DE TRANSMISSION ET DE PRÉCODEUR DANS UNE TRANSMISSION BASÉE SUR UN LIVRE DE CODES DE LIAISON MONTANTE
Abstract:
(EN) Techniques and apparatus for configuring transmission rank and/or precoder(s) to support uplink non-codebook based transmission are provided. One technique includes receiving sounding reference signal (SRS) resource(s) from a user equipment (UE), where each SRS resource is associated with one or more precoded ports. At least one of a transmission rank or a set of precoders is determined based on the SRS resource(s). An indication of at least one of the SRS resource(s) is signaled to the UE. The UE uses the indication of the at least one of the SRS resource(s) to send an uplink transmission.
(FR) L'invention concerne des techniques et un appareil permettant de configurer un rang de transmission et/ou un ou des précodeurs afin de prendre en charge une transmission basée sur un non-livre de codes de liaison montante. Une technique consiste à recevoir une ou des ressources de signal de référence de sondage (SRS) à partir d'un équipement d'utilisateur (UE), chaque ressource de SRS étant associée à un ou plusieurs ports précodés. Au moins un parmi un rang de transmission ou un ensemble de précodeurs est déterminé sur la base de la ou des ressources de SRS. Une indication d'au moins une des ressources de SRS est signalée à l'UE. L'UE utilise l'indication de la ou des ressources de SRS pour envoyer une transmission de liaison montante.
