Controllable CSI-RS density
Methods and apparatus for configuring, in a network node of a wireless communication network, a reference signal resource used to perform channel-state information, CSI, measurements with one or more wireless devices. In an example method, a reference signal resource is aggregated in one or more of a frequency and a time domain, and a density characteristic of the aggregated reference signal resource that is to be transmitted to the one or more wireless devices is adjusted.
