Abstract
(EN)
Systems and methods are disclosed herein for signaling a marker within a Channel Occupancy Time (COT). In some embodiments, a method performed by a wireless device for operating in unlicensed spectrum comprises obtaining a configuration of one or more slot format combinations. The slot format combinations comprise a slot format combination that comprises a value that indicates a marker within a COT comprising a plurality of slots. The marker identifies a specific time instance within the COT. The method further comprises receiving control information that identifies the slot format combination from within the obtained configuration and determining a type of the marker in the identified slot format combination from the value that indicates the marker. The method further comprises performing at least one of uplink transmission or downlink listening during the COT in accordance with the determined type of the marker and the specific time instance identified by the marker.

L'invention concerne des systèmes et des procédés permettant de signaler un marqueur dans un temps d'occupation de canal (COT). Dans certains modes de réalisation, un procédé mis en œuvre par un dispositif sans fil destiné à fonctionner dans un spectre sans licence consiste à obtenir une configuration d'une ou de plusieurs combinaisons de format d'intervalle. Les combinaisons de format d'intervalle comprennent une combinaison de format d'intervalle qui comprend une valeur qui indique un marqueur dans un COT comprenant une pluralité d'intervalles. Le marqueur identifie une instance temporelle spécifique dans le COT. Le procédé consiste en outre à recevoir des informations de commande qui identifient la combinaison de format d'intervalle de l'intérieur de la configuration obtenue et à déterminer un type du marqueur dans la combinaison de format d'intervalle identifiée provenant de la valeur qui indique le marqueur. Le procédé consiste en outre à effectuer au moins une transmission en liaison montante ou une écoute en liaison descendante pendant le COT en fonction du type déterminé du marqueur et de l'instance temporelle spécifique identifiée par le marqueur.
