Abstract
A method of an access network node of a carrier aggregation enabled cellular wireless communication system, and a method of a wireless terminal device of a carrier aggregation enabled cellular wireless communication system are disclosed. The method for the network node comprises identifying a need for an inter-band handover where a same physical frequency on which the access network node interacts with a wireless terminal device has more than one logical reference, wherein the wireless terminal device currently operates using a first logical reference, assigning a target frequency for the inter-band handover as a second logical reference for the physical frequency, and performing handover signalling with the wireless terminal device including the assigned target frequency. The method of the wireless terminal device comprises performing operation where a need for an inter-band handover occurs where a same physical frequency on which the wireless terminal device interacts with an access network node of the cellular wireless communication system has more than one logical reference, wherein the wireless terminal device currently operates using a first logical reference, and performing handover signalling with the access network node including receiving an assigned target frequency which is a second logical reference for the physical frequency. A network node, a wireless terminal device and computer programs for these for implementing the methods are also disclosed.
