1. An apparatus comprising:
a processor configured to:
cause a device to wirelessly communicate according to a first radio access technology (RAT) on a plurality of cells of a carrier aggregation configuration;
cause the device to operate at any given point in time in a first state (FS) for a first group of active cells of the plurality of cells and in a second state (SS) for a second group of active cells of the plurality of cells, wherein in the FS for a given cell the device does not monitor physical downlink control channel candidates for the given cell, and wherein in the SS for the given cell the device monitors physical downlink control channel candidates on physical resources configured by higher layers on a respective active bandwidth part (BWP) for the given cell; and
cause the device to switch, in response to a request received from a serving cell of the device, from operating in the FS to operating in the SS for at least one of:
at least one cell of the first group of active cells when the request is received in downlink control information, DCI, wherein the DCI also includes data scheduling for the serving cell, and
a first sub-group of cells of the first group of active cells when the request comprises multiple bits, and a single bit of the multiple bits corresponds to a specific group of cells that includes the first sub-group of cells.
