In this work we study the K-users MISO Broadcast Channel scenario under the so-called Distributed CSIT con guration, where each transmitter has a possibly di erent channel state estimate. Recently, the inconcistencies between the estimates at the di erent transmitters have been shown to lead to a signi cant performance's loss. Considering the high-SNR
regime, we develop a new transmission scheme that reduces the e ect of these mismatches, based on (i) a new precoding scheme as well as on (ii) a new method of combining di erent transmissions schemes to resolve the interference generated by retransmission of the interference while maximizing the data rate.
