Abstract
A network node for a Frequency Division Duplex, FDD, wireless communication network is provided. The network node includes processing circuitry configured to determine a transformation matrix for transforming an uplink codebook to a downlink codebook where the transformation matrix is based at least in part on channel state information, CSI. The processing circuitry is further configured to determine a first uplink codebook based at least in part on uplink signals, determine a first downlink codebook based at least in part on the transformation matrix and the first uplink codebook, and cause transmission of downlink signals to a wireless device based at least in part on the first downlink codebook.
