A method performed in a user equipment, UE, for enabling activation of a cell, the method comprising: - receiving an order for cell configuration from a network node; - receiving (410, 601) a configuration message from the network node; - determining (420, 601) if the received configuration message contains an indicator indicating whether the UE shall perform activation of the cell, and if so: -- activating (430, 606, 608) the cell upon configuration of the cell; -- otherwise, receiving the indicator in an on-demand fashion, and determining whether the indicator indicates that the terminal shall perform activation of the cell upon configuration, and if so: --- activating (430, 606, 608) the cell upon configuration of the cell; --- otherwise, receiving the indicator during initial access, and determining whether the indicator indicates that the terminal shall perform activation of the cell upon configuration, and if so: ---- activating (430, 606, 608) the cell upon configuration of the cell; ----- otherwise, receiving the indicator in a broadcast message and determining whether the broadcasted indicator indicates that the terminal shall perform activation of the cell upon configuration, and if so: ----- activating (430, 606, 608) the cell upon configuration of the cell. - receiving an order for cell configuration from a network node; - receiving (410, 601) a configuration message from the network node; - determining (420, 601) if the received configuration message contains an indicator indicating whether the UE shall perform activation of the cell, and if so: -- activating (430, 606, 608) the cell upon configuration of the cell; -- otherwise, receiving the indicator in an on-demand fashion, and determining whether the indicator indicates that the terminal shall perform activation of the cell upon configuration, and if so: --- activating (430, 606, 608) the cell upon configuration of the cell; --- otherwise, receiving the indicator during initial access, and determining whether the indicator indicates that the terminal shall perform activation of the cell upon configuration, and if so: ---- activating (430, 606, 608) the cell upon configuration of the cell; ----- otherwise, receiving the indicator in a broadcast message and determining whether the broadcasted indicator indicates that the terminal shall perform activation of the cell upon configuration, and if so: ----- activating (430, 606, 608) the cell upon configuration of the cell. -- activating (430, 606, 608) the cell upon configuration of the cell; -- otherwise, receiving the indicator in an on-demand fashion, and determining whether the indicator indicates that the terminal shall perform activation of the cell upon configuration, and if so: --- activating (430, 606, 608) the cell upon configuration of the cell; --- otherwise, receiving the indicator during initial access, and determining whether the indicator indicates that the terminal shall perform activation of the cell upon configuration, and if so: ---- activating (430, 606, 608) the cell upon configuration of the cell; ----- otherwise, receiving the indicator in a broadcast message and determining whether the broadcasted indicator indicates that the terminal shall perform activation of the cell upon configuration, and if so: ----- activating (430, 606, 608) the cell upon configuration of the cell. --- activating (430, 606, 608) the cell upon configuration of the cell; --- otherwise, receiving the indicator during initial access, and determining whether the indicator indicates that the terminal shall perform activation of the cell upon configuration, and if so: ---- activating (430, 606, 608) the cell upon configuration of the cell; ----- otherwise, receiving the indicator in a broadcast message and determining whether the broadcasted indicator indicates that the terminal shall perform activation of the cell upon configuration, and if so: ----- activating (430, 606, 608) the cell upon configuration of the cell. ----- otherwise, receiving the indicator in a broadcast message and determining whether the broadcasted indicator indicates that the terminal shall perform activation of the cell upon configuration, and if so: ----- activating (430, 606, 608) the cell upon configuration of the cell.
