Abstract
(EN)
According to some embodiments of the present disclosure, a method for receiving public warning system (PWS) information by a terminal may comprise the steps of: receiving system information including configuration information related to a coverage enhancement (CE) mode from a base station; in the coverage enhancement mode allowing an operation on the basis of the system information, receiving downlink control information (DCI), which indicates that the public warning system information is broadcasted in a system bandwidth, in a bandwidth that is narrower than the system bandwidth; and acquiring the public warning system information in the system bandwidth on the basis of the DCI.
(FR)
Selon certains modes de réalisation de la présente invention, un procédé de réception d'informations de système d'avertissement public (PWS) par un terminal peut comprendre les étapes consistant à : recevoir des informations du système comprenant des informations de configuration relatives à un mode d'amélioration de couverture (CE) d'une station de base; dans le mode d'amélioration de couverture permettant une opération sur la base des informations du système, recevoir des informations de commande de liaison descendante (DCI), qui indique que les informations du système d'avertissement public sont diffusées dans une bande passante du système, dans une bande passante qui est plus étroite que la largeur de bande du système; et acquérir les informations du système d'avertissement public dans la bande passante du système sur la base des DCI.
