Layer 2 relay to support coverage and resource-constrained devices in wireless networks
First Claim
1. A mobile communications relay device, comprising:
- a transceiver configured to exchange control signals with a network node;
a processor; and
a memory coupled to said processor and containing instructions that configure the processor to operate the transceiver to exchange said control signals,wherein said instructions further configure the processor to pass a first proper subset of said control signals to a remote device without operating according to said control signals, and to operate according to control signals in a second proper subset of said control signals that is distinct from the first proper subset thereby operating on behalf of said remote device to support communication between said remote device and said network node;
wherein said first proper subset includes RRC and PDCP control signals from an E-UTRAN protocol stack;
wherein said second proper subset includes RLC, MAC, and PHY control signals from the E-UTRAN protocol stack.

Abstract
Embodiments provide a mobile communications device that includes a processor configured to communicate with a transceiver and a memory. 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.
