Title
(EN) STARTING OFFSET FOR NEW RADIO-UNLICENSED (NR-U) UPLINK TRANSMISSION
(FR) DÉCALAGE INITIAL POUR UNE TRANSMISSION SENS MONTANT D'UNE NOUVELLE RADIO (NR-U) SANS LICENCE
Abstract
(EN)
Wireless communications systems and methods related to signaling transmission starting offsets for uplink transmissions in a frequency spectrum shared by multiple network operating entities are provided. A first wireless communication device communicates, with a second wireless communication device, a cyclic prefix (CP) extension length configuration for providing a gap duration for a listen-before-talk (LBT) associated with a first communication signal. The first wireless communication device communicates, with the second wireless communication device, the first communication signal including a CP extension having a length based on the CP extension length configuration.
(FR)
L'invention concerne des systèmes et des procédés de communication sans fil relatifs aux décalages initiaux de transmission de signalisation pour des transmissions sens montant dans un spectre de fréquence partagé par de multiples entités d'exploitation de réseau. Un premier dispositif de communication sans fil communique, avec un second dispositif de communication sans fil, une configuration de longueur d'extension de préfixe cyclique (CP) permettant de fournir une durée d'intervalle pour accès multiple avec écoute de porteuse (CSMA) associée à un premier signal de communication. Le premier dispositif de communication sans fil communique, avec le second dispositif de communication sans fil, le premier signal de communication comprenant une extension CP ayant une longueur basée sur la configuration de longueur d'extension CP.
