Abstract
There is provided a method in a node for a wireless communication network. The node is configurable with a plurality of radio carriers for radio transmission between the node and one or more other nodes of the wireless communication network. The plurality of radio carriers comprises at least a first carrier and a second carrier. The node is operable according to a protocol stack comprising at least a first layer and a second layer, wherein the second layer is higher than the first layer. The first layer is responsible for aggregation of the first and second radio carriers, and the second layer is responsible for duplication of data packets for transmission over the first and second carriers. The method comprises determining, at a first entity of the first layer, that the second carrier is activated or deactivated; and sending, from the first entity of the first layer to a first entity of the second layer, an indication of the activation or deactivation of the second carrier.
