Abstract
(EN)
Aspects of the disclosure provide a user equipment (UE). The UE receives configuration information of one or more sounding reference signal (SRS) resource sets. Each of the one or more SRS resource sets includes one or more SRS resources. The UE receives an SRS resource indicator (SRI). The SRI includes multiple bits to select a subset of the one or more SRS resources included in the one or more configured SRS resource sets. The UE determines a spatial quasi co-located (QCL) assumption for a physical uplink shared channel (PUSCH) transmission according to the selected subset of SRS resources.
(FR)
Selon certains aspects, l'invention concerne un équipement d'utilisateur (UE). L'UE reçoit des informations de configuration d'un ou plusieurs ensembles de ressources de signal de référence de sondage (SRS). Chacun du ou des ensembles de ressources SRS comprend une ou plusieurs ressources SRS. L'UE reçoit un indicateur de ressource SRS (SRI). Le SRI comprend de multiples bits afin de sélectionner un sous-ensemble de la ou des ressources SRS incluses dans l'ensemble ou les ensembles de ressources SRS configurées. L'UE détermine une hypothèse de quasi-colocalisation spatiale (QCL) en vue d'une transmission de canal physique partagé de liaison montante (PUSCH) selon le sous-ensemble sélectionné de ressources SRS.
