Abstract

La présente invention concerne un procédé et un appareil pour établir un rapport de qualité de liaison dans un système de communication sans fil supportant une adaptation de liaison. Un signal d'entrée portant des blocs de données dans un ou plusieurs intervalles de transmission d'un intervalle de rapport est reçu par un récepteur (30) de l'appareil. Une unité de mesure de qualité (31) fournit une mesure de qualité de liaison de l'intervalle de rapport courant. Une unité de correction (32) corrige la mesure de qualité de liaison en déterminant une perte SIR de la liaison, qui est induite par des réglages de paramètres de transmission non correspondants d'une couche physique. Ensuite, un rapport de qualité de liaison pour l'intervalle de rapport courant est basé sur la mesure de qualité de liaison corrigée, puis est transmise par l'émetteur (34) à l'unité de transmission, qui va adapter le réglage des paramètres de couche physique de manière conforme.
