Claim of US Patent No. 10,397,951

1. A method, performed in a first node in a wireless communication system, of accessing a shared media for directive signal transmission from the first node, the method comprising:receiving, from a second node, a pilot signal announcing a directive signal transmission between the second node and at least one further node, wherein the pilot signal has a narrower bandwidth than the announced directive signal transmission between the second node and the at least one further node;
predicting based on information in the received pilot signal, a collision rate between an intended directive signal transmission from the first node and the announced directive signal transmission, the information defining channel resources used by the announced directive signal transmission, wherein the prediction of the collision rate comprises estimating interference between the intended directive signal transmission from the first node and the announced directive signal transmission between the second node and the at least one further node; and
accessing the shared media based on the predicted collision rate.
