Method and device for digital information transmission with automatic retransmission request, or ARQ.

摘要

Method and device for digital information transmission, with automatic retransmission request should the message be poorly received. There is provision, in the transmitted frame, for sufficient room to be able to receive several (n) useful information blocks, so as to reabsorb an excessive delay of (r) due to the successive retransmissions. The decoder (2) provides the management microprocessor (5) with a confidence indicator (3). The Control block (COM) which leaves this decoder possesses an indicator (C) of the number of useful blocks transmitted in the frame. It is advantageously directed (6, 9) towards an HDLC component (8). <IMAGE>
