According to an example aspect of the present invention, there is provided a method comprising, determining at least one anchor control resource set among a plurality of control resource sets, wherein each of the at least one anchor control resource set defines a spatial source for multiple signal types, said multiple signal types comprising different downlink and uplink signals and channels, determining whether or not a given signal type is to inherit a spatial source of one of the at least one anchor control resource set and applying, in case of a positive determination, the spatial source of the at least one anchor control resource set for at least one signal of the given signal type.
