Claim 20:
21. A non-transitory computer storage medium storing a computer program comprising computer program code which, when run on a network node, causes the network node to:
obtain 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;
determine, 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 determining comprising determining occassionality of inter cell interference for the base stations from the signal strength measurements, and 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 being determined in accordance with the occassionality of inter cell interference; and
assign 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 for transmission of downlink reference signals.
