Abstract

A wireless telecommunications network node method, a wireless telecommunications network node and a computer program product are disclosed. The wireless telecommunications network node method comprises: selecting a first frequency channel as a transmission channel; transmitting information using said first frequency channel; and determining a transmission status of the information using the first frequency channel wherein when the determining determines that transmission of the information using the first frequency channel was successful, the method comprises transmitting further information using the first frequency channel and when the determining determines that transmission of the information using the first frequency channel was unsuccessful, the method comprises selecting a further frequency channel as the transmission channel and repeating the transmitting and determining using the further frequency channel. In this way, rather than trying to make an assessment of whether a particular channel is free or unused prior to making a transmission using that channel, instead the transmission occurs and an assessment is made of whether that transmission was successful or not. This enables shared, unmanaged or unlicensed spectrum to be used, whilst avoiding assuming that interference may occur even when it may not and avoiding potentially wasting useful transmission resources.
