Method for random-access communication in communication networks (1) with time-slotted transmission channels which are being accessed by a plurality of terminal devices (2), whereby the terminal devices (2) are provided with binary feedback (S/{overscore (S)}) by a common receiver (3), a positive feedback (S) indicating that a particular slot contained a successfully transmitted packet or a negative feedback ({overscore (S)}) indicating that the particular slot did not contain a successfully transmitted packet, and whereby dummy packets are transmitted by an auxiliary user (4) following the first negative feedback ({overscore (S)}) after a prior collision has been resolved to determine whether said negative ({overscore (S)}) feedback was due to a collision of packets in the respective slot or whether it was due to this slot having been empty.Unsuccessfully transmitted packets are re-transmitted in accordance with their respective position in an interval, which position is determined by the numeric value of a parameter assigned to each packet, which interval is divided into two portions by a predefined parameter (alpha), and which numeric values are randomized after a negative feedback ({overscore (S)}) occurred during the resolution of a collision. |
