Abstract

La présente invention se rapporte à un procédé et à un dispositif permettant de sélectionner un mode de transmission de données d'antenne. Selon le procédé, un terminal de transmission détermine, selon des informations d'état de canal, un mode de transmission de données adapté à un terminal de réception parmi un mode de diversité spatiale combinée avec la diversité de retard cyclique et un mode de multiplexage spatial combiné avec la diversité de retard cyclique (S502), et le terminal de transmission transmet des données d'antenne en utilisant le mode de transmission de données déterminé (S504). Le procédé technique de la présente invention résout le problème selon lequel le mode de transmission de données ne peut pas être sélectionné selon l'état du canal du système à cause de l'absence, dans la technologie apparentée, du procédé permettant de sélectionner le mode de transmission de données parmi le mode de diversité spatiale combinée avec la diversité de retard cyclique et le mode de multiplexage spatial combiné avec la diversité de retard cyclique, et permet de sélectionner adroitement un mode de transmission de données adapté parmi le mode de diversité spatiale combinée avec la diversité de retard cyclique et le mode de multiplexage spatial combiné avec la diversité de retard cyclique afin de transmettre des données, ce qui permet d'accroître la stabilité de la liaison et d'améliorer le débit du système.
