The effect of self-interference due to the increase of spatial correlation in a MIMO channel has become one of the limiting factors\r\ntowards the implementation of future network downlink transmissions. This paper aims to reduce the effect of self-interference\r\nin a downlink multiuser- (MU-) MIMO transmission by exploiting the available spatial and frequency diversity. The subcarrier\r\nallocation scheme can exploit the frequency diversity to determine the self-interference from the ESINR metric, while the spatial\r\ndiversity can be exploited by introducing the partial feedback scheme, which offers knowledge of the channel condition to the base\r\nstation and further reduces the effect before the allocation process takes place. The results have shown that the proposed downlink\r\ntransmission scheme offers robust bit error rate (BER) performance, even when simulated in a fully correlated channel, without\r\nimposing higher feedback requirements on the base controller.
