Dynamically Or Statically ?
I will try put this in this way . Though eNB may support carrier aggregation , but UE . During UE capability procedure , ue informs UE about the ttype  of aggregation it supports (like inter , intra with specific band info).
Later on channel condition , eNB may use one or both for scheduling downlink or uplink resource.

For carrier aggregation, Scell(s) need to be configured through RRC signaling. This may be done statically or dynamically (e.g. based on measurements of the SCell)
Scell activation/deactivation may be done dynamically by scheduler.
