Classification: CPC H | IPC H

Claim 18:
19. A first radio communication device for authenticating the first radio communication device with a network, the first radio communication device comprising processing circuitry, the processing circuitry being configured to cause the first radio communication device to:
obtain credentials for a network subscription to the network;
download a radio protocol stack from the network;
negotiating how the radio protocol stack is to be split between the first radio communication device and a second radio communication device, wherein the radio protocol stack comprises a user plane protocol and a control plane protocol, the user plane protocol and the control plane protocol are split between the first radio communication device and the second radio communication device;
obtain an upper part of the radio protocol stack, according to which radio protocol stack the first radio communication device is configured to communicate with the network, wherein the upper part of the radio protocol stack corresponds to the user plane protocol;
authenticate with the network; and
provide, to the second radio communication device, at least one key, as derived from the credentials during the authenticating, for use by the second radio communication device when executing the remaining part of the radio protocol stack for communication between the second radio communication device and the network.
