Abstract

La présente invention se rapporte à un procédé d'interprétation d'informations de contrôle. Le procédé selon l'invention est destiné à être utilisé dans un système de communication mobile comprenant un terminal et une station de base. Dans le procédé selon l'invention, le terminal reçoit, en provenance de la station de base, des informations de contrôle contenant des informations de blocs de transport et des informations d'indication d'allocation d'un port d'antenne à un signal de référence de démodulation (DM-RS) ; le terminal vérifie un nombre des blocs de transports alloués au terminal sur la base des informations de blocs de transport, et interprète les informations d'indication d'allocation de port d'antenne DM-RS sur la base du nombre de blocs de transport.
