Title (EN) RADIO LINK ADAPTATION IN RADIO COMMUNICATION SYSTEMS
(FR) ADAPTATION DE LIAISON RADIO DANS DES SYSTÈMES DE COMMUNICATION
Abstract:
(EN) Method, preferably implemented in a transmission node (81, 91, 1 1 ), for performing link adaptation of a radio link (106, 108, C1 ), comprising: determining (72) an estimation error of an estimated quality of the radio link (106, 108, C1 ), adapting (74) a Modulation and/or Coding Scheme, referred to as MCS, decision input value, which is based on the estimated quality of the radio link, by increasing the MCS decision input value if the determined estimation error exceeds a predetermined threshold, selecting (75) a MCS based on the MCS input value as adapted.
(FR) L’invention concerne un procédé, de préférence mis en œuvre dans un nœud de transmission (81, 91, 11), permettant l’adaptation de liaison d’une liaison radio (106, 108, C1), consistant : à déterminer (72) une erreur d’estimation d’une qualité estimée de la liaison radio (106, 108, C1), à adapter (74) une valeur d’entrée de décision de principe de modulation et/ou de codage, appelé MCS, ladite valeur étant basée sur la qualité estimée de la liaison radio, en augmentant la valeur d’entrée de décision de MCS si l’erreur d’estimation déterminée dépasse un seuil préétabli, à sélectionner (75) un MCS sur la base de la valeur d’entrée de MCS telle qu’adaptée.
