Abstract

Embodiments of the invention describe a novel solution to enhance network service to devices with limited or no connectivity. Embodiments include network-aware nodes deployed by an end-user or operator which are configured by a network to achieve enhanced coverage, enhanced throughput, enhanced battery life, and mitigation of cell boundary experiences, etc. Embodiments provide these benefits to a specified or non-specified set of user equipment (e.g., neighboring user equipment). The service expansion terminal can be an available user equipment that is idle and that has been volunteered, assigned, or is a dedicated node with limited user interface and designed for carrying out enhanced coverage, enhanced throughput, enhanced battery life, and the mitigation of cell boundary experiences, etc. Embodiments may therefore provide low-cost, flexible deployment, and mobility thereby enabling boundaryless service.

First claim

What is claimed is:

1. A method for enhancing network service, the method comprising:
receiving, by a first user equipment (UE), user plane data for a second UE from a base station in accordance with a first transmission scheme; and
sending, by the first UE, the user plane data to the second UE over a device-to-device (D2D) link based on a second transmission scheme without communicating control plane information, that corresponds to the user plane data, over the D2D link, the control plane information being directly communicated from the base station to the second UE, wherein the second UE is subscribed to the base station, wherein the second UE is proximately located relative to the first UE, wherein the first UE is transparent to the second UE such that the second UE is unaware of the user plane data being routed through the first UE, and wherein the first UE is configured to provide enhanced wireless coverage to the second UE over that provided by the base station.

2. The method of claim 1 , wherein a signal strength of a communication link between the second UE and the first UE is greater than a signal strength of a communication link between the second UE and the base station.

3. The method of claim 1 , wherein the second UE is a mobile device.

4. The method of claim 1 , wherein the first UE is configured to extend wireless service to the second UE.

5. The method of claim 1 , wherein the first UE is configured to increase data throughput to the second UE over that provided by the base station.

6. The method of claim 1 , wherein the first UE is configured to extend wireless service into an area with limited wireless coverage provided by the base station.

7. The method of claim 1 , wherein the first UE is a user equipment (UE) enabled to function as the first UE based on a user configuration.

8. The method of claim 1 , wherein the first UE enhances network service of a network, and the first UE is a user equipment (UE) enabled to function as the first UE based on an acknowledgment signal from the network.

9. The method of claim 1 , further comprising:
prior to the receiving the user plane data:
receiving, by the first UE from the base station, resource configuration information, wherein the first UE communicates the user plane data to the second UE in accordance with the received resource configuration.

10. The method of claim 1 , wherein the first UE is selected by the based station from a plurality of UEs, the method further comprising:
prior to the receiving the user plane data:
transmitting, by the base station, testing data to the plurality of UEs;
receiving, by the base station, testing responses from the plurality of UEs;
determining, by the base station, capacity information associated with the plurality of UEs; and
selecting, by the base station, the first UE based on the determined capacity information.

11. The method of claim 1 , wherein the receiving comprises receiving the user plane data and the control plane information for the second UE from the base station.

12. A user equipment (UE) comprising:
a receiver receiving user plane data for a second UE from a base station in accordance with a first transmission scheme; and
a transmitter coupled to a processor, the transmitter sending the user plane data to the second UE over a device-to-device (D2D) link based on a second transmission scheme without communicating control plane information, that corresponds to the user plane data, over the D2D link, the control plane information being directly communicated from the base station to the second UE, wherein the second UE is subscribed to the base station, wherein the second UE is proximately located relative to the UE, wherein the UE is transparent to the second UE such that the second UE is unaware of the user plane data being routed through the UE, and wherein the UE provides enhanced wireless coverage to the second UE over that provided by the base station.

13. The UE of claim 12 , wherein a signal strength of a communication link between the second UE and the UE is greater than a signal strength of a communication link between the second UE and the base station.

14. The UE of claim 12 , wherein the second UE is a mobile device.

15. The UE of claim 12 , wherein the UE extends wireless service to the second UE.

16. The UE of claim 12 , wherein the UE increases data throughput to the second UE over that provided by the base station.

17. The UE of claim 12 , wherein the UE extends wireless service into an area with limited wireless coverage provided by the base station.

18. A non-transitory computer-readable storage medium having instructions stored thereon that, when executed by one or more processors, cause the one or more processors to perform operations for enhancing network service, the operations comprising:
receiving, by a first user equipment (UE), user plane data for a second UE from a base station in accordance with a first transmission scheme; and
sending, by the first UE, the user plane data to the second UE over a device-to-device (D2D) link based on a second transmission scheme without communicating control plane information, that corresponds to the user plane data, over the D2D link, the control plane information being directly communicated from the base station to the second UE, wherein the second UE is subscribed to the base station, wherein the second UE is proximately located relative to the first UE, wherein the first UE is transparent to the second UE such that the second UE is unaware of the user plane data being routed through the first UE, and wherein the first UE is configured to provide enhanced wireless coverage to the second UE over that provided by the base station.
