Abstract
A method at a wireless device for determining parameters of a precoder to a network node, in a wireless communication system, is provided. The method comprises: selecting a subset of beams from a plurality of orthogonal beams, the selected subset of beams having phases; quantizing the phases of the selected subset of beams, the quantization being beam dependent; and sending the selected subset of beams and the quantized phases to the network node, wherein the selected subset of beams and the quantized phases are part of the parameters of the precoder. A wireless device for carrying out this method is also provided.
