Abstract
It is provided a method for assisting downlink interference estimation in a cellular network. The method is performed in a network node of the cellular network and comprises the steps of: estimating an average transmit power of the network node in a future time period, resulting in a scaling factor indicating the average transmit power of the network node in relation to a reference transmit power of the network node; transmitting, in a resource element allocated to interference estimation, a reference signal for downlink interference estimation with a transmission power which is based on the scaling factor; and refraining from transmitting in a resource element in at least one instance where another network node transmits a reference signal for downlink interference estimation. A corresponding network node, computer program and computer program product for assisting downlink interference estimation are also presented.
