Title
(EN) RETRANSMISSION SCHEMES AND OPTIMIZATIONS FOR PRECONFIGURED UPLINK RESOURCES
(FR) SYSTÈMES DE RETRANSMISSION ET OPTIMISATIONS POUR DES RESSOURCES DE LIAISON MONTANTE PRÉCONFIGURÉES
Abstract
(EN)
Exemplary embodiments include methods for transmitting uplink (UL) data, by a user equipment (UE), using preconfigured uplink resources (PUR) in a radio access network (RAN). Such methods include receiving, from a network node in the RAN, a first PUR configuration, and transmitting, based on the first PUR configuration, a first UL data message to the network node Such methods also include receiving, from the network node, a first acknowledgement (PUR ACK) of the first UL data message. The first PUR ACK indicates whether the first UL data message was correctly or incorrectly received by the network node, and includes information related to subsequent UL transmissions using PUR (e.g., a second PUR configuration, a fallback indication, etc.). Some embodiments also include transmitting a second UL data message. Other embodiments include complementary methods performed by a network node, as well as UEs network nodes and UEs configured to perform such methods.

Des modes de réalisation donnés à titre d'exemple comprennent des procédés de transmission de données en liaison montante (UL), au moyen d'un équipement utilisateur (UE), à l'aide de ressources de liaison montante préconfigurées (PUR) dans un réseau d'accès radio (RAN). De tels procédés consistent à recevoir, d'un nœud de réseau dans le RAN, une première configuration PUR et à transmettre, sur la base de la première configuration PUR, un premier message de données UL au nœud de réseau. De tels procédés comprennent également la réception, depuis un nœud de réseau, d'un premier accusé de réception (ACK PUR) du premier message de données UL. Le premier ACK PUR indique si le premier message de données UL était correctement ou incorrectement reçu par le nœud de réseau et comprend des informations relatives à des transmissions UL ultérieures utilisant des PUR (par exemple, une seconde configuration PUR, une indication de repli, etc.). Certains modes de réalisation comprennent également la transmission d'un second message de données UL. D'autres modes de réalisation comprennent également des procédés complémentaires mis en œuvre par un équipement utilisateur, ainsi que des nœuds de réseau d'UE et des UE configurés pour mettre en œuvre de tels procédés.
