Abstract
A method and network node for interference-aware dimension reduction via orthonormal basis selection are disclosed. According to one aspect, a method includes determining a beamformer for each wireless device (WD), each beamformer being based at least in part on an interference covariance matrix; determining a power in each dimension reduction basis vector based at least in part on the determined beamformers; and selecting a subset of the dimension reduction basis vectors based on the determined power. A number of selected dimension reduction basis vectors is less than a number of antenna elements of the network node. The method also includes multiplying a received signal vector by a dimension reduction matrix having as rows the selected subset of the dimension reduction basis vectors. The multiplying results in a reduced signal vector having a dimension equal to the number of selected rows of the dimension reduction matrix.
