Title
(EN) NEW RADIO (NR) FOR SPECTRUM SHARING
(FR) NOUVELLE RADIO (NR) POUR LE PARTAGE DE SPECTRE
Abstract
(EN) Wireless communications systems and methods related to coordinating shared radio resources for spectrum sharing are provided. A spectrum resource control unit allocates a first resource for exclusive access by a first network operating entity in a spectrum. The exclusive access is configured for at least one of a network information communication or a feedback communication. The spectrum resource control unit allocates a second resource in the spectrum for shared access by the first network operating entity and a second network operating entity. The shared access is configured for at least a downlink control information communication. The spectrum resource control unit transmits, to the first network operating entity and the second network operating entity, a configuration indicating the first resource allocated for exclusive access by the first network operating entity and the second resource allocated for shared access by the first network operating entity and the second network operating entity.
(FR) L'invention concerne des systèmes de communication sans fil et des procédés associés à la coordination de ressources radio partagées pour le partage de spectre. Une unité de commande de ressource de spectre attribue une première ressource pour un accès exclusif par une première entité d'exploitation de réseau dans un spectre. L'accès exclusif est configuré pour au moins l'une d'une communication d'informations de réseau ou d'une communication de rétroaction. L'unité de commande de ressource de spectre attribue une seconde ressource dans le spectre pour un accès partagé par la première entité d'exploitation de réseau et une seconde entité d'exploitation de réseau. L'accès partagé est configuré pour au moins une communication d'informations de commande de liaison descendante. L'unité de commande de ressource de spectre transmet, à la première entité d'exploitation de réseau et à la seconde entité d'exploitation de réseau, une configuration indiquant la première ressource attribuée pour un accès exclusif par la première entité d'exploitation de réseau et la seconde ressource attribuée pour un accès partagé par la première entité d'exploitation de réseau et la seconde entité d'exploitation de réseau.
