Abstract
Systems and methods are disclosed for controlling ON/OFF operation of a Secondary Cell (SCell) in a cellular communications network. In some embodiments, the SCell is a License Assisted Access (LAA) SCell that operates in an unlicensed frequency band. In some embodiments, a method of operation of a network node in the cellular communications network to dynamically control ON/OFF operation of a SCell of the cellular communications network comprises measuring activity of other wireless systems on a channel utilized by a SCell while the SCell is in an OFF state, determining whether to transition the SCell to an ON state based on the activity of the other wireless systems measured on the channel, turning the SCell ON upon determining that the SCell is to be transitioned to the ON state, and keeping the SCell in the OFF state upon determining that the SCell is not to be transitioned to the ON state.
