FLEXIBLE NB-IoT MULTI-CARRIER OPERATION ACROSS RADIO FREQUENCY BANDS

摘要

The invention discloses a method for improving NarrowBand Internet-of-Things radio network utilization by more efficiently and flexibly allocating available frequency spectrum resources to an UE. The objective to provide a method which allows efficient NB-IoT multi-carrier operation across different radio frequency bands or NB-IoT/ LTE mother cells will be solved by a method for improving NarrowBand Internet of Things (NB-IoT) radio network utilization by more efficiently and flexibly allocating available frequency spectrum resources to an UE, wherein system information messages and/or dedicated signaling exchanged between an eNodeB and the UE are extended by specific parameters, setups and requests, so that multi-carrier operations are performable across all radio frequency bands even if the UE is already connected to the eNodeB.
