Abstract
(EN)
Methods, systems, and devices for wireless communications are described. A bandwidth part (BWP) configuration may be identified for a user equipment (UE), where the BWP configuration is part of a shared radio frequency spectrum band. In some cases, a base station may transmit a resource configuration for the BWP to the UE that indicates a set of subbands for the BWP and an indication of which subbands are available for the resource contention and possible subsequent communications. The UE and base station may determine a set of time-frequency resources for at least one downlink signal to be transmitted from the base station to the UE based on the BWP and available subbands. In some cases, the resource configurations for the BWP may include a reference signal configuration, a semi-persistent scheduling configuration, a control resource set configuration, or a combination thereof for the available subbands of the BWP.

L’invention concerne des procédés, des systèmes et des dispositifs destinés à la communication sans fil. Une configuration de partie de bande passante (BWP) peut être identifiée pour un équipement utilisateur (UE), la configuration BWP faisant partie d'une bande de spectre radioélectrique partagée. Dans certains cas, une station de base peut transmettre une configuration de ressources pour la BWP à l'UE qui indique un ensemble de sous-bandes pour la BWP et une indication selon laquelle les sous-bandes sont disponibles pour la contention de ressources et pour des communications ultérieures possibles. L'UE et la station de base peuvent déterminer un ensemble de ressources temps-fréquence pour au moins un signal de liaison descendante devant être transmis de la station de base à l'UE sur la base des BWP et des sous-bandes disponibles. Dans certains cas, les configurations de ressources pour la BWP peuvent comprendre une configuration de signal de référence, une configuration de programmation semi-persistante, une configuration d'ensemble de ressources de commande ou une combinaison desdites configurations pour les sous-bandes disponibles de la BWP.
