Zusammenfassung:A method (500) performed by a network node (102, 104). The method includes determining to transmit a first reference signal. The method also includes determining whether a second reference signal should be transmitted. The method also includes transmitting the first reference signal using a first precoder. The method also includes transmitting the second reference signal as a result of determining that the second reference signal should be transmitted. The second reference signal is transmitted using a second precoder that is complementary to the first precoder such that the second reference signal occupies a first part of a channel not occupied by the first reference signal.
