Abstract
A system comprising a source node () and a relay node (). The relay node senses a radio spectrum to provide first sensing data indicating the availability of a signal channel at the relay node. The source node senses the radio spectrum to provide second sensing data indicating the availability of the signal channel at the source node. The source node or relay node generates a channel availability parameter based on the first or second sensing data, respectively. The channel availability parameter comprises fewer bits of information than whichever of the first or second sensing data is used to generate the channel availability parameter. The source node determines whether to send message information to the relay node based on a sensing result obtained by combining the channel availability parameter with whichever one of the first and second sensing data is not used to generate the channel availability parameter.
