| Abstract: | Downlink enhanced MIMO is one of the key technologies for LTE-Advanced. In this article, LTE R8 and R9 of the multi-user MIMO transmis-sion model have been discussed, and the multi-user MIMO major issues based on LTE-A have been discussed. Various plans for design of downlink control, signaling pilot, feedback and enhanced code design have been compared. The application scenarios of multi-user MIMO and the possibilities of supporting more than two layer for each user have been discussed. At last, the progress of standardization has been introduced. |
