  • Inter-Band Handover of the Same Physical Frequency
    Publication number: 20240080726
    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.
