US Patent 10070431 LTE operation in small cells using dynamic shared spectrum

Systems, methods, and apparatus may be used to provide assistance for connection procedures in a hierarchical network where macro cells may be operating in licensed spectrum while small cells may be operating in dynamic and shared spectrums, such as TVWS. This may be done, for example, to allow an LTE system performing carrier aggregation (CA) to reconfigure itself to change from a supplementary cell (SuppCell) in one dynamic and shared spectrum channel to a SuppCell in another dynamic and shared spectrum channel.
