Abstract
The present disclosure relates to a method (100) for determining scheduling assignments for reducing nonlinear signal distortion, performed in a network node of a wireless communications network. The network node comprises an antenna array arranged to perform beamforming. The method (100) comprises obtaining (S10) channel state information, CSI, relating to respective channels between the network node and at least two wireless devices served by the network node. The method further comprises determining (S20) precoding vectors to the at least two wireless devices based on the obtained CSI. The method also comprises determining (S30) at least two frequency scheduling assignments for each of the at least two wireless devices. The method additionally comprises estimating (S40), for each of the determined at least two frequency scheduling assignments, a respective transmitted nonlinear signal distortion to each of the at least two wireless devices based on the obtained CSI. The method yet further comprises selecting (S50) a frequency scheduling assignment of the determined at least two frequency scheduling assignments based on the estimated transmitted nonlinear signal distortions.
