Title
(EN) PHYSICAL RESOURCE AND TRANSMISSION PARAMETER CONFIGURATION WITHOUT A RADIO RESOURCE CONTROL CONNECTION
(FR) CONFIGURATION DE PARAMÈTRE DE TRANSMISSION ET DE RESSOURCE PHYSIQUE SANS CONNEXION DE COMMANDE DE RESSOURCE RADIO
Abstract
(EN)
Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently signaling configurations of physical resources and transmission parameters to a user equipment (UE) for small data transmissions (for example, data transmissions in an inactive or idle state). A base station may broadcast or multicast downlink control information (DCI) in one or more control channels that schedules data transmissions in a set of data channels. The base station may then multicast one or more configurations in each of the data channels, and a UE may decode one of the data channels to determine a configuration for a small data transmission. Because the configurations may be transmitted in the data channels in addition to system information or paging information, a base station may have access to sufficient resources to provide suitable configurations to a UE for communications in an inactive or idle state.

L'invention concerne des procédés, des systèmes et des dispositifs de communication sans fil. D'une manière générale, les techniques décrites permettent de signaler efficacement des configurations de ressource physique et de paramètres de transmission à un équipement utilisateur (UE) pour des petites transmissions de données (par exemple, des transmissions de données dans un état inactif ou inactif). Une station de base peut diffuser ou diffuser des informations de commande de liaison descendante (DCI) dans un ou plusieurs canaux de commande qui programme des transmissions de données dans un ensemble de canaux de données. La station de base peut ensuite diffuser une ou plusieurs configurations dans chacun des canaux de données, et un UE peut décoder l'un des canaux de données pour déterminer une configuration pour une petite transmission de données. Du fait que les configurations peuvent être transmises dans les canaux de données en plus d'informations de système ou d'informations de radiomessagerie, une station de base peut avoir accès à des ressources suffisantes pour fournir des configurations appropriées à un UE pour des communications dans un état inactif ou inactif.
