Apparatuses, realtime-stations, computer programs, and methods for scheduling of traffic in wireless networks are provided. In one embodiment, a method is provided for scheduling of traffic in a wireless networks including real-time stations intending to send real-time traffic and best-effort stations sending best effort traffic. The method can include overhearing for a predetermined period of time the traffic by a station which intends to send real-time traffic, and if from the overhearing the station concludes that there is already a primary station transmitting real-time access markers, assuming by the station a sequence number based on the number of real-time stations which already are sending real-time traffic.
