Abstract

There is provided a method for determining a radiation beam pattern. The method is performed by a network node. The method comprises transmitting probe signals, the probe signals being orthogonal to cell-specific reference signals (CRS) transmitted by the network node. The method comprises receiving responses to the probe signals from wireless devices, wherein each response comprises a measurement report based on reception of the transmitted probe signals at each wireless device. The method comprises determining a radiation beam pattern based on the received measurement reports.
