Abstract
A method for transmitting successive messages forming a frame, implemented by a telecommunications system with M sources (S1, . . . , SM), possibly L relays (R1, . . . , RL) and a destination, M≥2, L≥0. The method implements a HARQ mechanism and includes: transmitting, from the destination to the nodes (R1, R2, . . . , RL+M), a control message indicating its set (SD,t−1) of correctly decoded source messages; determining, by each node (R1, R2, . . . , RL+M), whether at least one message from its set of correctly decoded source messages does not belong to the set of source messages correctly decoded by the destination; and transmitting a binary indicator by a node (R1, R2, . . . , RL+M) to the destination indicating the result of the determination.
