1. A method in a wireless communication device capable of device-to-device, D2D, operation and configured with at least one secondary cell, SCell, the method comprising:
- receiving a command from a network node to activate or deactivate the SCell;
determining at least a D2D traffic activity level of the wireless communication device; and
determining, by the wireless communication device at the time the command is received, whether to apply or ignore the received command based at least in part on the determined D2D traffic activity level.

Abstract
According to some embodiments, a wireless communication device capable of device-to-device, D2D, operation is configured with at least one secondary cell, SCell. The wireless communication device receives a command from a network node to activate or deactivate the SCell. The wireless communication device determines at least its D2D traffic activity level and determines whether to apply or ignore the received command based at least in part on the determined D2D traffic activity level.

9. A method in a network node for activating or deactivating a secondary cell, SCell, for a wireless communication device capable of device-to-device (D2D) operation and configured with at least one SCell, the method comprising:
-
obtaining, by the network node, a D2D traffic activity level of the wireless communication device and a wireless access network (WAN) traffic activity level of the wireless communication device; determining, by the network node, whether to activate or deactivate the SCell based at least in part on the D2D traffic activity level and the WAN traffic activity level, wherein the SCell is served to the wireless communication device by the network node or another network node; and sending an activation or deactivation command from the network node to the wireless communication device in response to a determination to activate or deactivate the SCell. - View Dependent Claims (10, 11, 12, 13)

14. A wireless communication device capable of device-to-device (D2D) operation characterized in that the wireless communication device comprises a processor and a memory containing instructions executable by said processor, the wireless communication device, upon execution of the instructions by the processor, being operable to:
-
receive a command from a network node to activate or deactivate at least one secondary cell, SCell;
determine at least a D2D traffic activity level of the wireless communication device; anddetermine, by the wireless communication device at the time the command is received, whether to apply or ignore the received command based at least in part on the determined D2D traffic activity level. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)

22. A network node for activating or deactivating a secondary cell, SCell, for a device-to-device (D2D) capable wireless communication device, the network node characterized by a processor and a memory containing instructions executable by said processor, the network node, upon execution of the instructions by the processor, being operable to:
-
obtain, at the network node, a D2D traffic activity level of the wireless communication device and a wireless access network (WAN) traffic activity level of the wireless communication device; determine, at the network node, whether to activate or deactivate the SCell based at least in part on the D2D traffic activity level and the WAN traffic activity level, wherein the SCell is served to the wireless communication device by the network node or another network node; and send an activation or deactivation command from the network node to the wireless communication device in response to a determination to activate or deactivate the SCell. - View Dependent Claims (23, 24, 25, 26)
