Abstract
Various solutions for coverage extension allowing improved high-frequency and high-data-rate cellular coverage of devices located in conditions of poor network coverage in mobile communications are described. The described solutions may extend coverage, for example, via a sidelink interface between two mobile devices, a relay device in good coverage and a remote device that may be in poor coverage, thus allowing the remote device to communicate using the relay device as a backhaul link to a cellular network.
Claims17
A method, comprising:
- communicating, by a processor of an apparatus, with a network node via a first interface;
- indicating, by the processor, to the network node a capability to function as a relay node;
- communicating, by the processor, with a remote node via a second interface;
- and
- relaying, by the processor, a packet between the network node and the remote node via the first interface and the second interface,
- wherein the communicating with the remote node comprises receiving or transmitting user-plane data with the remote node on a high-frequency (HF) band.

A method, comprising:
- communicating, by a processor of an apparatus, with a network node via a first interface;
- communicating, by the processor, with a relay node via a second interface;
- indicating, by the processor, to at least one of the network node and the relay node a capability to support a coverage enhancement via the relay node;
- communicating, by the processor, a packet with the network node via the relay node;
- and
- receiving, by the processor, different user-plane configurations and control-plane configurations with respect to different remote nodes.
