A technique for controlling a duty cycle of a transmitter in a mobile device is provided. When the mobile device is wirelessly connected to a telecommunications network, discontinuous reception and transmission is provided by a duty cycle including an active state and an inactive state. As to a method aspect of the technique, a switching option for initiating the inactive state after the active state is determined. It is assessed whether a timer of the mobile device triggers a future transmission at a corresponding transmission time. If a time difference between the switching option and the transmission timer exceed a predefined minimum duration, the inactive state is initiated.
