Abstract

Concept for transmitting payload data from a transmitter to a receiver via a communication channel within a time interval, wherein channel-coded data packets are generated from the payload data, wherein each of the channel-coded data packets has packet core data corresponding to a packet identification of the respective channel-coded data packet, and wherein the packet core data is coded with a channel code of higher redundancy than the payload data. The channel-coded data packets are sent without any return channel to the receiver, which decodes packet core data of a first received channel-coded data packet of the time interval. If error-free decoding of the first channel-coded data packet fails, packet core data of at least one second received channel-coded data packet of the time interval are decoded to determine a suitable further channel-coded data packet for combination with the first channel-coded data packet to acquire, on account of the combination, an increased code gain for decoding of the payload data.
