Abstract
A method, network node and wireless device (WD) for dual codebook configuration and channel state information (CSI) combining for large scale active antenna systems (AAS) are disclosed. According to one aspect, a method in a network node includes triggering the WD to transmit in succession or simultaneously, a horizontal CSI report reporting a horizontal CSI set for a horizontal direction of the array and a vertical CSI report reporting a vertical CSI set for a vertical direction of the array, the horizontal CSI set being mapped to a row of the array and the vertical CSI set being mapped to a column of the array. The method also includes receiving the horizontal and vertical CSI reports from the WD, and combining the horizontal and vertical CSI sets into a combined CSI set for at least one of scheduling and beamforming.
