A method and apparatus for selecting multiple transport formats and transmitting multiple transport blocks (TBs) in a transmission time interval simultaneously with, multiple hybrid automatic repeat request (H-ARQ) processes in a wireless communication system are disclosed. Available physical resources and H-ARQ processes associated with the available physical resources are identified and channel quality of each of the available physical resources is determined. Quality of service (QoS) requirements of higher layer data to be transmitted are determined. The higher layer data is mapped to at least two H-ARQ processes. Physical transmission and H-ARQ configurations to support QoS requirements of the higher layer data mapped to each H-ARQ process are determined. TBs are generated from the mapped higher layer data in accordance with the physical transmission and H-ARQ configurations of each H-ARQ process, respectively. The TBs are transmitted via the H-ARQ processes simultaneously.

L'invention concerne un procédé et un appareil qui permettent de sélectionner plusieurs formats de transport, et de transmettre plusieurs blocs de transport (TB) simultanément dans un intervalle de temps de transmission, en utilisant plusieurs processus de demande de répétition automatique hybride (H-ARQ) dans un système de communication sans fil. Des ressources physiques disponibles et des processus H-ARQ associés auxdites ressources physiques sont identifiées et la qualité de la voie pour chaque ressource physique disponible est déterminée. Des critères de qualité de service (QoS) de données de la couche supérieure à transmettre sont déterminées. Les données de la couche supérieure sont mappées relativement à au moins deux processus H-ARQ. Des configurations de transmission physique et de H-ARQ destinées à servir de support à des critères QoS des données de la couche supérieure mappées relativement à chaque processus H-ARQ sont déterminées. Des TB sont générés à partir des données mappées de la couche supérieure, conformément aux configurations de transmission physique et de H-ARQ de chaque processus H-ARQ, respectivement. Les TB sont transmis simultanément par l'intermédiaire des processus H-ARQ.
