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 β 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 β 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.
A method of transmitting reference signals in subframes in a radio frame in a cellular communication system comprising at least a first network node in a first cell providing a first measurement bandwidth γf, which is more narrow than a first full downlink bandwidth βf of said first network node, the method comprising:
An arrangement configured to transmit reference signals in subframes in a radio frame in a cellular communication system comprising at least a first network node in a first cell providing a first measurement bandwidth γf, which is more narrow than a first full downlink bandwidth βf of said first network node, the arrangement comprising:
