    • Concept for transmitting payload data (112-m) from a transmitter (110-m) to a receiver (120) via a communication channel within a time interval (T), wherein a plurality of channel-coded data packets (210-n) are generated from the payload data (112-m) within the time interval (T), wherein each of the channel-coded data packets comprises packet core data (212-n) 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 (112-m). The plurality of channel-coded data packets (210-n) are sent, within the time interval (T), without any return channel to the receiver (120), which comprises a decoder (DEC) adapted to decode packet core data (212-1) of a first received channel-coded data packet (210-1) of the time interval (T), and, if error-free decoding of the first channel-coded data packet (210-1) so as to obtain the payload data (112-m) fails, to decode packet core data (212-2) of at least one second received channel- coded data packet (210-2) of the time interval (T) so as to determine a suitable further channel-coded data packet of the time interval for combination with the first channel-coded data packet so as to obtain, on account of the combination, an increased code gain for decoding of the payload data.
    • 用于经由时间间隔(T)中的通信信道从发射机(110-m)向接收机(120)发送有效载荷数据(112-m)的概念,其中多个信道编码数据分组(210-n) 在时间间隔(T)内从有效载荷数据(112-m)产生,其中每个信道编码数据分组包括与相应信道编码数据分组的分组标识对应的分组核心数据(212-n) ,并且其中所述分组核心数据用比所述有效载荷数据(112-m)更高冗余的信道码进行编码。 多个信道编码数据分组(210-n)在时间间隔(T)内被发送到接收机(120),没有任何返回信道,其包括适于解码分组核心数据(212)的解码器(DEC) -1),并且如果第一信道编码数据分组(210-1)的无差错解码,以获得所述时间间隔(T)的第一接收信道编码数据分组(210-1) 有效载荷数据(112-m)失败,以对时间间隔(T)的至少一个第二接收信道编码数据分组(210-2)的分组核心数据(212-2)进行解码,以便确定合适的另外的信道 用于与第一通道编码数据分组组合的时间间隔的编码数据分组,以便由组合获得用于解码有效载荷数据的增加的代码增益。
