Abstract: A method is disclosed for a network node configured to transmit wireless communication signals using beam forming and configured to apply any of one or more data carrying beam widths for transmission of data carrying signals dedicated to a specific wireless communication device. The method comprises determining one or more requirement parameters for transmission of synchronization signals, wherein the one or more requirement parameters comprise a desired synchronization signal beam width and a minimum effective power, and wherein the determined desired synchronization signal beam width is larger than a minimum one of the data carrying beam widths.
