Abstract

La présente divulgation concerne un procédé de surveillance, un dispositif de surveillance et un support de stockage. Le procédé de surveillance est appliqué à un terminal. Le procédé consiste : à déterminer au moins une sous-bande LBT, la sous-bande LBT étant configurée pour prendre en charge un canal de commande de liaison descendante physique (PDCCH) ; et à surveiller le PDCCH sur la base de la sous-bande LBT. La présente divulgation peut amener un terminal à surveiller un PDCCH sur la base de différentes sous-bandes LBT, ce qui permet d'empêcher un terminal non autorisé d'être bloqué en communication de liaison descendante.
