Patent

CA 2432400

The invention relates to a data transmission method and a radio system that comprises a first (260) transceiver and a second transceiver (264) that are in radio contact with each other. The first transceiver (260) comprises means (500, 504) for forming data blocks for transmission in such a manner that the data blocks are given identifiers for identification. The second transceiver (264) comprises means (512) for receiving data blocks transmitted and retransmitted by the first transceiver, and means (524) for detecting a failure in receiving a data block. The second transceiver (264) comprises means (530) for maintaining information on the position of a window belonging to a finite identifier space, and means (524) for comparing the identifiers of the re-received data block and the earlier received data block with each other and for defining the data blocks as the same, and means (524) for combining the data blocks defined as the same.

L'invention porte sur un procédé de transmission de données et sur un système radio qui comprend un premier (260) et un second émetteur-récepteur (264) qui sont en contact radio. Le premier émetteur-récepteur (260) comprend un dispositif (500, 504) permettant de former des blocs de données destinés à être transmis à des identificateurs pour leur identification. Le second émetteur-récepteur (264) comprend un dispositif (512) destiné à recevoir des blocs de données transmis et retransmis par le premier émetteur-récepteur et un dispositif (524) destiné à détecter une panne à la réception des blocs de données. Le second émetteur-récepteur (264) comprend un dispositif (530) destiné à conserver des informations relatives à la position d'une fenêtre appartenant à un espace d'identificateur fini, et un dispositif (524) destiné à comparer les identificateurs du bloc de données reçu à nouveau et du bloc de données reçu antérieurement et définir les blocs de données comme étant identiques, et un dispositif (524) destiné à combiner les blocs de données précités.
