| Abstract(in English) | In the LTE standard, the close-loop system is used for high throughput. Mobile feeds channel state information (CSI) back by 4 bits PMI of channel direct information and CQI of channel quality information to the base station. Since LTE-A requires higher throughput, MU-MIMO and CoMP is considered to apply. But it is difficult to cancel other user's signal with conventional LTE feedback. In this reason, the new feedback system which is extension of LTE system is proposed. In case of quantizing channel information, if base station needs more detailed CSI information, CSI feedback needs many bits. The analog feedback is one of the solution. In this paper, we propose feedback method of combination of digital and analog information and MU-MIMO precoding scheme. |
