In particular, the present document relates to the request of an access channel from a wireless device to a base station of the digital cellular telecommunications network. A method for controlling one or more transmissions between a wireless device (100) and a base station (110) is described. The one or more transmissions comprise at least an initial transmission. The method comprises determining the quality of a radio uplink between the wireless device (100) and the base station (110), the quality being based on at least one parameter associated with a previous transmission; setting a control parameter for controlling the transmission between the wireless device (100) and the base station (110) based on the determined quality of the radio uplink; and transmitting the initial transmission.
