Abstract
An evolved Node B (eNB) serves as a primary serving cell (PCell) providing a primary component carrier (PCC) in a licensed spectrum to a user equipment (UE) in a carrier aggregation (CA) scheme. A secondary component carrier (SCC) is provided in an unlicensed spectrum. The eNB monitors parameters of bandwidths in the unlicensed spectrum, when at least one of the parameters indicates a change in availability of a select one of the bandwidths, the eNB generates a control indicator defining the change in availability of the bandwidth and broadcasts the control indicator to the UE, wherein the control indicator affects a modification in a transceiver of the UE associated with the bandwidth.
