Abstract
(EN)
There is disclosed a method of operating a wireless device (10) in a wireless communication network, the wireless device (10) being triggered for transmission of first control information on a first transmission resource associated to a first transmission quality, the wireless device (10) further being triggered for transmission of second control information on a second transmission resource associated to a second transmission quality; the method comprising transmitting control signaling based on multiplexing first control information and second control information on a common transmission resource, the first control information being mapped to the common transmission resource based on at least one first scaling factor, and the second control information being mapped to the common transmission resource based on at least one second scaling factor. The disclosure also pertains to related devices and methods.

L'invention concerne un procédé de fonctionnement d'un dispositif sans fil (10) dans un réseau de communication sans fil, le dispositif sans fil (10) étant déclenché afin de transmettre les premières informations de commande sur une première ressource de transmission associée à une première qualité de transmission, le dispositif sans fil (10) étant en outre déclenché afin de transmettre les secondes informations de commande sur une seconde ressource de transmission associée à une seconde qualité de transmission ; le procédé consiste à transmettre une signalisation de commande en fonction du multiplexage des premières informations de commande et des secondes informations de commande sur une ressource de transmission commune, les premières informations de commande étant mises en correspondance avec la ressource de transmission commune en fonction d'au moins un premier facteur de mise à l'échelle, et les secondes informations de commande étant mises en correspondance avec la ressource de transmission commune en fonction d'au moins un second facteur de mise à l'échelle. L'invention concerne également des dispositifs et des procédés associés.
