Abstract
The present disclosure presents a method performed in a first node in a wireless communication system, of accessing a shared channel for transmission from the first node to at least one second node. The method comprises the step of receiving, from a third node a pilot signal announcing reception in the third node, wherein the pilot signal comprises information enabling estimation of a channel response from the first node to the third node; estimating, using the pilot signal, a channel response from the first node to the third node and predicting, based on the estimated channel response, an interference level at the receiver of the third node of a directive transmission from the first node to the second node; and accessing the shared channel based on the predicted interference level.
