Title
(EN) DYNAMIC SCHEDULING OFFSET ADAPTATION IN UE POWER SAVING
(FR) ADAPTATION DE DÉCALAGE DE PLANIFICATION DYNAMIQUE DANS UNE ÉCONOMIE D'ÉNERGIE D'UE
Abstract
(EN)
A method and apparatus for dynamically adapting scheduling parameter(s) to achieve power savings. A user equipment may be configured with one or more offsets between scheduled PDCCH and PDSCH transmissions. The user equipment may receive from a network an indication to dynamically change these offsets. If the user equipment sleeps through a first transmission of this indication, upon next receiving the indication the user equipment may update, for example, the offset in a time domain resource allocation table. The indication to dynamically change an offset may be an indication of an offset comprising fewer slots. A change to the offset, with which downlink transmission is expected by the user equipment, may be disabled. A network node may be configured to transmit downlink traffic to the user equipment according to a configured offset and/or according to an offset the network node indicated to the user equipment.
(FR)
L'invention concerne un procédé et un appareil d'adaptation dynamique d'un ou de plusieurs paramètre(s) de planification pour réaliser des économies d'énergie. Un équipement utilisateur peut être configuré avec un ou avec plusieurs décalages entre des transmissions planifiées de PDCCH et de PDSCH. L'équipement utilisateur peut recevoir d'un réseau une indication permettant la modification dynamique de ces décalages. Si l'équipement utilisateur reste en veille au cours d'une première transmission de cette indication, lors de la réception suivante de l'indication, l'équipement utilisateur peut par exemple mettre à jour le décalage dans une table d'attribution de ressources de domaine temporel. L'indication de modification dynamique d'un décalage peut être une indication d'un décalage comprenant un nombre réduit d'intervalles. Une modification du décalage, selon laquelle une transmission en liaison descendante est attendue par l'équipement utilisateur, peut être désactivée. Un nœud de réseau peut être configuré pour transmettre un trafic de liaison descendante à l'équipement utilisateur selon un décalage configuré et/ou selon un décalage du nœud de réseau indiqué à l'équipement utilisateur.
