Title
(EN) MEASUREMENT REPORT ON USER EQUIPMENT CLEAR CHANNEL ASSESSMENT STATUS
(FR) SIGNALEMENT DE MESURE SUR L'ÉTAT D'ÉVALUATION DE CANAL LIBRE D'ÉQUIPEMENT UTILISATEUR
Abstract
(EN)
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine that a serving base station of the UE has obtained access to a wireless channel of a shared radio frequency spectrum band during a transmission opportunity that is separate from a scheduled uplink transmission by the UE. The UE may perform, based at least in part on the determination, a clear channel assessment (CCA) procedure on the wireless channel during a designated quiet portion of the transmission opportunity. The UE may transmit an unsolicited CCA status report to the serving base station during the transmission opportunity based at least in part on the CCA procedure.

L’invention concerne des procédés, des systèmes et des dispositifs destinés aux communications sans fil. Un équipement utilisateur (UE) peut déterminer qu'une station de base de desserte de l'UE a eu accès à un canal sans fil d'une bande partagée de spectre des radiofréquences pendant une opportunité de transmission qui est séparée d'une transmission planifiée de liaison montante par l'UE. L'UE peut effectuer, sur la base au moins en partie de la détermination, une procédure d'évaluation de canal libre (CCA) sur le canal sans fil pendant une partie silencieuse désignée de l'opportunité de transmission. L'UE peut transmettre un signalement d'état non sollicité de CCA à la station de base de desserte pendant l'opportunité de transmission en fonction, au moins en partie, de la procédure de CCA.
