Abstract
Dans un aspect général, un débit auquel des transmissions MIMO sont déclenchées à partir de dispositifs de communication sans fil est amené à varier. Un premier dispositif de communication sans fil peut être configuré pour transmettre sans fil un premier ensemble de messages à un premier débit de transmission à un second dispositif de communication sans fil. Le premier dispositif de communication sans fil peut en outre être configuré pour recevoir des transmissions MIMO à partir du second dispositif de communication sans fil. Le premier dispositif de communication sans fil peut en outre être configuré pour générer des premières informations de canal sur la base de champs d'apprentissage respectifs dans chacune des premières transmissions MIMO ; déterminer un débit auquel les premières informations de canal sont générées ; faire varier le premier débit de transmission à un second débit de transmission différent sur la base du débit auquel les premières informations de canal sont générées ; et transmettre sans fil un second ensemble de messages au second débit de transmission au second dispositif de communication sans fil.
