Apparatus, method, and computer program

A UE comprising a means for storing a cell configuration for use when it is in an active mode, a means for sending cell measurements of a cell associated with the stored cell configuration to a network node, and a means for activating, once the cell measurements have been sent, the stored cell configuration while the UE is in an active mode or entering the active mode. Cell configuration may be stored whilst in an idle or inactive mode. Means for activating the stored configuration may be autonomous. Cell measurements may be performed after receiving a conditional cell activation message from the network node. Activating the stored configuration may be dependent on a threshold being met. The threshold may be based on synchronisation signal block reference signal received power or synchronization signal block reference signal received quality. The cell may comprise Secondary Cell (SCell) or Primary Secondary Cell (PSCell). Also disclosed is a method of allocating resources of a cell configuration to a UE, storing information of the allocated resources at the network node and sending allocated resources information to the UE for the UE to use when in or entering the active mode.
