Abstract
(EN)
The present specification provides a method for transmitting and receiving downlink control information (DCI) in a wireless communication system supporting narrow band-Internet of things (NB-IoT). Specifically, a terminal monitors at least one first candidate PDCCH in a first search space and at least one second candidate PDCCH in a second search space, wherein the first search space and the second search space may partially or entirely overlap each other on a time axis. Thereafter, the terminal may search for a first DCI in the at least one first candidate PDCCH and a second DCI in the at least one second candidate PDCCH, wherein the sum of the number of the at least one first candidate PDCCH and the number of the at least one second candidate PDCCH may be less than or equal to a specific number.
(FR)
La présente invention concerne un procédé de transmission et de réception d’informations de commande de liaison descendante (DCI) dans un système de communication sans fil prenant en charge l’Internet des objets à bande étroite (NB-IoT). Spécifiquement, un terminal surveille au moins un premier PDCCH candidat dans un premier espace de recherche et au moins un second PDCCH candidat dans un second espace de recherche, le premier espace de recherche et le second espace de recherche pouvant se recouvrir intégralement ou partiellement sur un axe des temps. Après cela, le terminal peut recherche des premières DCI dans le ou les premiers PDCCH candidats et des secondes DCI dans le ou les seconds PDCCH candidats, la somme du nombre du ou des premiers PDCCH candidats et du nombre du ou des seconds PDCCH candidats pouvant être inférieure ou égale à un nombre spécifique.
