Abstract

Des modes de réalisation de la présente invention concernent un procédé et un dispositif de configuration de sous-trame. Le procédé comprend les étapes suivantes : un terminal reçoit des informations de configuration de sous-trame MBSFN envoyées par une station de base; le terminal détermine, selon les informations de configuration de sous-trame MBSFN, l'existence d'un intervalle de garde dans une sous-trame MBSFN, et l'emplacement et la longueur de l'intervalle de garde. L'intervalle de garde est une zone sans support de données. Pendant la transmission, si le moment terminal de l'arrivée des données est en retard, le retard se produira dans l'intervalle de garde de façon à ne pas interférer avec d'autres transmissions de données, assurant ainsi la qualité de transmission du terminal dans le processus de réception de données.
