(EN) MULTIPLE SEMI-PERSISTENT SCHEDULED TRANSMISSION CONTROL BY A SINGLE DOWNLINK CONTROL INFORMATION MESSAGE
(FR) COMMANDE DE TRANSMISSION PROGRAMMÉE MULTIPLE SEMI-PERSISTANTE PAR UN MESSAGE UNIQUE D'INFORMATIONS DE COMMANDE DE LIAISON DESCENDANTE
Abstract
(EN)
Methods, systems, and devices for wireless communications are described. A UE may be configured to transmit more than one set of semi-persistent scheduled (SPS) transmissions to a base station. The base station may indicate, within the configuration, a group of SPS transmission sets. The base station may determine to reconfigure one or more of the SPS transmission sets (e.g., due to a change in channel conditions). The base station may indicate an updated configuration for the more than one SPS transmission sets via a single downlink control information (DCI) message. In some cases, the more than one SPS transmission sets corresponds to the group of SPS transmission sets. After receiving the updated configuration for the SPS transmissions sets, the UE may adjust the SPS configurations accordingly and communicate with the base station using the adjusted configurations.

L'invention concerne des procédés, des systèmes et des dispositifs pour communications sans fil. Un UE peut être configuré pour transmettre plus d'un ensemble de transmissions programmées semi-persistantes (SPS) à une station de base. La station de base peut indiquer, à l'intérieur de la configuration, un groupe d'ensembles de transmissions SPS. La station de base peut déterminer qu'il convient de reconfigurer un ou plusieurs des ensembles de transmissions SPS (p. ex. du fait d'un changement dans des conditions de canal). La station de base peut indiquer une configuration actualisée pour la pluralité d'ensembles de transmissions SPS via un message unique d'informations de commande de liaison descendante (DCI). Dans certains cas, la pluralité d'ensembles de transmissions SPS correspond au groupe d'ensembles de transmissions SPS. Après avoir reçu la configuration actualisée pour les ensembles de transmissions SPS, l'UE peut adapter les configurations de SPS en conséquence et communiquer avec la station de base en utilisant les configurations adaptées.
