Abstract
(EN)
Wireless communications systems and methods related to frequency resource mapping for uplink control channel communications and autonomous uplink communications in a frequency spectrum shared by multiple network operating entities are provided. A first wireless communication device identifies a first configuration from a plurality of configurations for mapping an uplink resource indicator to resources in a plurality of subbands. The first wireless communication device communicates with a second wireless communication device, a subband priority configuration. The first wireless communication device communicates, with the second wireless communication device, the uplink resource indicator. The first wireless communication device communicates, with the second wireless communication device, an uplink communication signal using a first resource of the resources based on the uplink resource indicator, the subband priority configuration, and the first configuration.

L'invention concerne des systèmes et des procédés de communication sans fil se rapportant à un mappage de ressources de fréquence pour des communications de canal de contrôle de liaison montante et des communications de liaison montante autonomes dans un spectre de fréquence partagé par de multiples entités d'exploitation de réseau. Un premier dispositif de communication sans fil identifie une première configuration parmi une pluralité de configurations pour mapper un indicateur de ressource de liaison montante par rapport à des ressources dans une pluralité de sous-bandes. Un premier dispositif de communication sans fil indique, avec un second dispositif de communication sans fil, une configuration de priorité de sous-bande. Le premier dispositif de communication sans fil indique, avec second dispositif de communication sans fil, un indicateur de ressource de liaison montante. Le premier dispositif de communication sans fil indique, avec le second dispositif de communication sans fil, un signal de communication de liaison montante à l'aide d'une première ressource des ressources sur la base de l'indicateur de ressource de liaison montante, la configuration de priorité de sous-bande, et la première configuration.
