Title
(EN) TIME-DEPENDENT ADAPTATION OF A WAKE-UP SIGNAL CONFIGURATION
(FR) ADAPTATION EN FONCTION DU TEMPS D'UNE CONFIGURATION DE SIGNAL DE RÉVEIL
Abstract
(EN)
A base station transmits an indication of a configuration indicating one or more time-variable parameters for a group-specific wake-up signal (WUS) to an associated group of user equipment (UEs). The base station determines a value of the one or more time-variable parameters based on a time associated with the group-specific WUS and transmits the group-specific WUS to the group of UEs based on the determined value. A UE in the group of UEs receives the indication of the configuration from the base station and determines a value of the one or more time-variable parameters based on a time associated with the group-specific WUS. The UE monitors for the group-specific WUS based on the determined value.

L'invention concerne une station de base qui transmet une indication d'une configuration indiquant au moins un paramètre variable dans le temps pour un signal de réveil spécifique à un groupe (WUS) à un groupe associé d'équipements utilisateur (UE). La station de base détermine une valeur de l'au moins un paramètre variable dans le temps sur la base d'un temps associé au WUS spécifique à un groupe et transmet le WUS spécifique à un groupe au groupe d'UE sur la base de la valeur déterminée. Un UE dans le groupe d'UE reçoit l'indication de la configuration en provenance de la station de base et détermine une valeur de l'au moins un paramètre variable dans le temps sur la base d'un temps associé au WUS spécifique à un groupe. L'UE surveille le WUS spécifique à un groupe sur la base de la valeur déterminée.
