Abstract
(EN)
Wireless communications systems and methods related to communications in a network that supports data transmitted in an unlicensed frequency band and a licensed frequency band are provided. A first wireless communication device communicates, with a second wireless communication device, a configuration indicating a first resource in an unlicensed frequency band and a second resource in a licensed band. The first wireless communication device communicates, with the second wireless communication device in the unlicensed frequency band, a first communication signal based on the configuration. The first wireless communication device communicates with the second wireless communication device in the licensed frequency band, a second communication signal based on at least one of a channel status of the unlicensed frequency band or a transmission parameter associated with at least one of the first communication signal or the second communication signal.

La présente invention concerne des systèmes de communications sans fil et des procédés se rapportant à des communications dans un réseau qui prend en charge des données transmises dans une bande de fréquences non autorisée et une bande de fréquences sous licence. Un premier dispositif de communication sans fil communique, avec un second dispositif de communication sans fil, une configuration indiquant une première ressource dans une bande de fréquences sans licence et une seconde ressource dans une bande sans licence. Le premier dispositif de communication sans fil communique, avec le second dispositif de communication sans fil dans la bande de fréquences sans licence, un premier signal de communication sur la base de la configuration. Le premier dispositif de communication sans fil communique avec le second dispositif de communication sans fil dans la bande de fréquences autorisée, un second signal de communication sur la base d'au moins un élément parmi un état de canal de la bande de fréquences non autorisée ou un paramètre de transmission associé à au moins un élément parmi le premier signal de communication ou le second signal de communication.
