Estimating the term…
In a radio system where wireless nodes are in contact, the wireless nodes are enabled to exchange information with adjacent nodes. In addition, distant nodes out of range for direct communication can be communicated with by forwarding data over multiple hops. The wireless nodes are configured to perform sensing of at least one radio resource. A node can be adapted to combine the sensing measurement data into a sensing result, such as an estimate of the probability of whether the resource is free or not. The sensing performed in a node is distributed to at least one other wireless node. Each wireless node can, therefore, access sensing information from at least one other wireless node located in the vicinity of the wireless node. Based on the collective information from at least one other node, a wireless node can make an improved decision if a particular radio resource is free to use or not.
A wireless node (300) for use in a radio system, the wireless node being adapted to be in contact with and exchange information with other wireless nodes of a radio system, the wireless node being adapted to perform sensing of at least one radio resource, characterized in that the wireless node comprises:
A method in a wireless node for determining access to a radio spectrum in a radio system, wherein the wireless node is in contact with and exchange information with other wireless nodes of the radio systems, and where the wireless node performs (501) sensing of at least one radio resource, characterized by the steps of:
