Abstract
A method () for precoding a signal. The method includes determining (s), based on uplink, UL, measurements, a spatial domain (SD) precoding vector and a frequency domain (FD) precoding vector for a downlink (DL) transmission of the signal. The method also includes applying (s) the FD precoding vector to the signal over subcarriers for carrying the signal, thus producing a modified signal. The method further includes applying (s) the SD precoding vector to the modified signal to produce a precoded signal, wherein the SD precoding vector is common for all said subcarriers in one symbol.
