A transmission scheme for spatial multiplexing MIMO systems allows use of SIC at the receiver with a single HARQ process or multiple HARQ processes. Error detection bits are added to an information block to generate and transport block (TDB) for a single HARQ instance having information bits and error detection bits. The transport block is then divided into two or more parts referred to herein as sub-blocks. Each sub-block is encoded according to a different modulation and coding scheme (MCS). The sub-blocks are combined to form two or more code-words for transmission to a receiving station.

Selon linvention, un schéma de transmission pour des systèmes à entrées/sorties multiples (MIMO) à multiplexage spatial permet lutilisation de SIC dans le récepteur avec un processus HARQ unique ou des processus HARQ multiples. Des bits de détection derreurs sont ajoutés à un bloc de données pour générer et transporter un bloc (TDB) pour une instance HARQ unique comportant des bits de données et des bits de détection derreurs. Le bloc de transport est ensuite divisé en au moins deux parties désignées ici comme étant des sous-blocs. Chaque sous-bloc est codé suivant un schéma de modulation et codage (MCS) différent. Les sous-blocs sont combinés pour former au moins deux mots de code à transmettre à une station réceptrice.
