Title
(EN) DOWNLINK MONITORING IN TELECOMMUNICATION SYSTEMS
(FR) SURVEILLANCE DE LIAISON DESCENDANTE DANS DES SYSTÈMES DE TÉLÉCOMMUNICATION
Abstract
(EN)
Example embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media for downlink (DL) monitoring in telecommunication systems. In example embodiments, a first device determines that data is to be transmitted via a second device towards a third device. The first device determines whether time for actively monitoring transmission from the second device is to be extended to receive a response for the data from the third device via the second device. Ifthe time is determined to be extended, the first device transmits, to the second device, the data and an indication for extending the time. The first device then receives the response from the third device via the second device in the extended time.

La présente invention concerne, selon des modes de réalisation donnés à titre d'exemple, des dispositifs, des procédés, des appareils et des supports de stockage lisibles par ordinateur permettant la surveillance de liaison descendante (DL) dans des systèmes de télécommunication. Dans des modes de réalisation donnés à titre d'exemple, un premier dispositif détermine que des données doivent être transmises par l'intermédiaire d'un deuxième dispositif vers un troisième dispositif. Le premier dispositif détermine si le temps de surveillance active de la transmission depuis le deuxième dispositif doit être étendu pour recevoir une réponse pour les données provenant du troisième dispositif par l'intermédiaire du deuxième dispositif. S'il est déterminé que le temps doit être étendu, le premier dispositif transmet, au deuxième dispositif, les données et une indication pour étendre le temps. Le premier dispositif reçoit ensuite la réponse du troisième dispositif par l'intermédiaire du deuxième dispositif dans le temps étendu.
