Zusammenfassung:A wireless device (UE1) transmits downlink interference-related information to a transmission point (TP1). The wireless device (UE1) generates this information by listening (604) to reference signals associated with a first reference signal resource (TP1) as well as with a second reference signal resource (TP2). The wireless device (UE1) uses these reference signals to estimate a first channel matrix relating to the first reference signal resource and a second channel matrix relating to the second reference signal resource. Using the estimated first and second channel matrices, the wireless device (UE1) derives (605) a pair of precoding matrices. Precoding matrix indicators representing the precoding matrix pair are sent (606) to the transmission point (TP1).
