MAC PROTOCOL FOR DIRECTIVE TRANSMISSIONS

摘要

The disclosure relates to radio access systems, and more specifically to methods for media access in radio access systems. The disclosure relates to 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 comprises three steps. The first step is receiving, from a second node, a pilot signal announcing a directive signal transmission to or from the second node. The second step is 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 the channel resources used by the announced directive signal transmission and the third step is accessing the shared media based on the predicted collision rate.
