Dual In-Band/Out-Band Radio Access System Field

摘要

There is provided a system of interacting relay nodes, each being configured to provide an in-band cellular radio access and an out-band radio access for at least one user eguipment within the coverage area of a corresponding relay node via at least one in-band cellular radio access link and at least one out-band radio access link, respectively; to transmit user data related to the in-band cellular radio access via first cellular radio access backhaul link and user data related to the out-band radio access via a second cellular radio access backhaul link; and to communicate with the at least one other relay node in order to per-form at least radio control-related functionalities between the interconnected relay nodes.
