1. A network node, comprising:
processing circuitry configured to:
estimate spatial transmission information, STI, for each of a plurality of wireless devices serviced by a plurality of network nodes;
determine spatial separability among the plurality of wireless devices based at least in part on the estimated STI for each of the plurality of wireless devices; and
cause scheduling of the plurality of wireless devices on the same communication resources based at least in part on the determined spatial separability, the scheduling of the plurality of wireless devices on the same communication resources includes causing each of the plurality of network nodes to precode transmission on the same communication resources.
