Abstract: A wireless network has a duty-cycle limitation, which defines a total transmission time budget and an average transmission time. A device (100) has a controller (102) for controlling the transmission of data according to the duty-cycle limitation. The controller stores past transmission time usage of the device in sequences of buckets, and determines a bucket budget of transmission time. A basic transmission time budget is assigned which is smaller than the average transmission time of the corresponding time interval, and additional transmission time is allocated to allow for temporally exceeding the average transmission time. The additional transmission time is based on the total transmission time budget and the past transmission time usage of past buckets in combination with the future basic transmission time budget of future buckets, which past, current and future buckets together cover the duty-cycle period.
