The transceiver is configured to exchange control signals with a network node. The memory contains instructions that when executed by the processor configure the processor to operate the transceiver to exchange the control, signals. The instructions further configure the processor to pass a first proper subset of the control signals to a remote device without operating according to the control signals, and to operate according to control signals in a second proper subset of the control signals. The processor is thereby configured to operate on behalf of a remote communication device to support communication between the remote communication device and the network node.
