Title (EN) METHODS AND SYSTEM FOR USING MULTI-BLOCK BURSTS IN HALF DUPLEX SUBSCRIBER UNIT TRANSMISSIONS
(FR) PROCEDES ET SYSTEME D'UTILISATION DE RAFALES MULTIBLOCS DANS LES EMISSIONS EN SEMI-DUPLEX PAR DES UNITES D'ABONNES
Abstract:
(EN) A method and system for extending channel access in a wireless communication system employing half-duplex subscriber units (100) is provided. The subscriber units (100) transmit (86) multi-block bursts to improve the burst throughput over half-duplex subscriber units that transmit only single-block bursts. The number of blocks per burst is selected (65) based on the code rate used and may be selected in a manner that also maximizes the system throughput. The subscriber unit includes a block processor (152) for assembling the blocks of data with overhead based on the code rate, a burst formatter (162) for combining the blocks and formatting the combination based on the code rate, and a process manager (146) for selecting the number of blocks to be transmitted in each transmit burst.
(FR) La présente invention concerne un procédé et un système d'extension de l'accès dans un système de communications sans fil employant des unités d'abonnés en semi-duplex (100). Les unités d'abonnés (100) émettent (68) des rafales multiblocs pour améliorer le débit en rafales passant par des unités d'abonnés en semi-duplex qui n'émettent que des rafales à bloc unique. Le nombre de blocs par rafale est choisi (65) en fonction du débit utilisé, et il peut être choisi d'une façon qui porte aussi au maximum le débit du système. L'unité d'abonné comprend un processeur de blocs (152) chargé d'assembler les blocs de données avec un en-tête ayant pour base le débit, un formateur de rafales (162) chargé de combiner les blocs et de formater la combinaison sur la base de la vitesse de code, et un gestionnaire de processus (146) chargé de choisir le nombre de blocs à émettre dans chaque rafale.
