Abstract: A method for estimating a signal to interference and noise ratio of a communication link between a fist node and a second node of a wireless communication network, the network comprising a number of further communication links between said first node and a number of further nodes. The method comprises, at the first node, providing first estimates of useful signal powers on all the links; providing second estimates of the signal powers on the link and on the further communication links on the basis of, jointly, the first estimate of the signal power on the link and the first estimates of the signal powers on the further links; estimating the signal to interference and noise ratio as a ratio between the second estimate of the signal power on the link and a power term comprising a sum of the second estimates of the signal powers on the further links.
