Title (EN) RELAYING METHOD AND DEVICE AND RECIPIENT WITH RETURN IN AN OMAMRC SYSTEM
(FR) PROCEDE, DISPOSITIF DE RELAYAGE ET DESTINATAIRE AVEC RETOUR DANS UN SYSTEME OMAMRC
Abstract:
(EN) The present invention relates to a method (1) for relaying messages via a half-duplex relay intended for a telecommunications system with M sources (S1,..., SM), L relays (R1..., RL) and a destination (D), M>1, L≥1, according to an orthogonal multiple access scheme of the transmission channel between the L relays and the destination, comprising the following steps: decoding via a relay (R1..., RL) of M messages each being associated with a frame and coming from a source among the M sources with detection of errors on the messages, transmission from the relay (R1..., RL) to the destination (D) of a signal (xR) representative of a least one portion of the set of the messages for which no errors have been detected by the relay conditional on authorization (NACK, Ât) from the destination, transmission from the relay (R1..., RL) to the destination (D) of a monitoring signal indicating a set (SR, t 1) of messages for which no errors have been detected by this relay, this transmission of the monitoring signal occurring before the transmission of the representative signal (xR).
(FR) La présente invention se rapporte à un procédé (1) de relayage de messages par un relais half-duplex destiné à un système de télécommunication à M sources (S1,..., SM), L relais (R1..., RL) et une destination (D), M>1, L≥1, selon un schéma d'accès multiple orthogonal du canal de transmission entre les L relais et la destination, comportant les étapes suivantes: décodage par un relais (R1..., RL) de M messages chacun associé à une trame et provenant d'une source parmi les M sources avec détection d'erreurs sur les messages, transmission du relais (R1..., RL) vers la destination (D) d'un signal (xR) représentatif d'au moins une partie du jeu des messages pour lesquels aucune erreur n'a été détectée par le relais sous condition d'une autorisation (NACK, Ât) provenant de la destination, transmission du relais (R1..., RL) vers la destination (D) d'un signal de contrôle indiquant un jeu (SR, t−1) de messages pour lesquels aucune erreur n'a été détectée par ce relais, cette transmission du signal de contrôle intervenant avant la transmission du signal (xR) représentatif.
