Abstract
There is provided mechanisms for assigning physical resource blocks to base stations in a cell deployment for transmission of downlink reference signals. A method is performed by a network node. The method comprises obtaining reports from terminal devices in the cell deployment, each report indicating location-wise signal strength measurements of base stations for one of the terminal devices. The method comprises determining, based on the obtained reports, whether to group the physical resource blocks in four sets of physical resource blocks or to group the physical resource blocks in less than four sets of physical resource blocks. The method comprises assigning the determined four or less sets of physical resource blocks to the base stations such that no two adjacent cells in the cell deployment are assigned to the same set of physical resource blocks. The method comprises initiating transmission of the downlink reference signals from the base stations in the assigned physical resource blocks.
