摘要
In an automatic repeat request procedure (ARQ), a first message is transmitted from a first computer unit to a second computer unit. Upon detection of a transmission error in the first message, a back-signalling message is coded in the second computer unit and transmitted to the first computer unit. The back-signalling message has at least one request field having the length of exactly one bit. A second message is requested by means of the request field. The second message contains additional information required for the error correction of the first message, or is the repetition of a message already transmitted or lost. The second message is transmitted to the second computer unit and decoded in the second computer unit together with the first message.
