A method and an arrangement for transmitting reference signals in a radio frame in a cellular communication system comprising at least one network node having a measurement bandwidth γ, which is more narrow than a full downlink bandwidth &bgr; of said network node. Subframes only carrying reference signals, which are to be transmitted from said network node may be transmitted over a temporarily reduced transmission bandwidth α, which is at least equally wide as the measurement bandwidth Y provided by the network node, and more narrow than the full downlink bandwidth &bgr; of the network node. The use of a reduced transmission bandwidth leads to that less reference signals are transmitted, and thereby transmission power will be saved.
