Abstract

A method for allocating resources for device-to-device transmission between two or more user equipment (UEs) includes transmitting, from a first UE to a second UE, a resource allocation configuration for device-to-device communications. A resource request for a device-to-device transmission is received from the second UE. In response to the resource request, a resource for the device-to-device transmission is selected at the first UE. A resource grant is transmitted to the second UE. The resource grant identifies the selected resource. A device-to-device transmission is received from the second UE over the selected resource.

Claims (23)

1. A method for configuring radio resources for device-to-device (D2D) communications between a first user equipment (UE) and a second UE, the method comprising:

receiving, at the first UE from a base station, a first message comprising a first resource pool, wherein the first resource pool includes a plurality of radio resources to be used for D2D communications;

transmitting, from the first UE to the second UE, a second message comprising a second resource pool, wherein the second resource pool includes a subset of the plurality of radio resources of the first resource pool to be used by the second UE for sending a D2D transmission to the first UE, wherein the first UE is within a network coverage and the second UE is outside of the network coverage; and

receiving, at the first UE from the second UE, a D2D transmission using at least one radio resource from the second resource pool.

2. The method of claim 1 , wherein the first UE receives information of the second resource pool from the base station via a radio resource control (RRC) message.

3. The method of claim 1 , wherein the second UE selects the at least one radio resource from the second resource pool.

4. The method of claim 3 , wherein the second UE operates in an autonomous selection mode.

5. A first user equipment (UE), comprising:

at least one processor;

one or more non-transitory computer-readable storage medium coupled to the at least one processor and storing programming instructions for execution by the at least one processor, wherein the programming instructions, when executed, cause the first UE to perform operations comprising:

receiving, from a base station, a first message comprising a first resource pool, wherein the first resource pool includes a plurality of radio resources to be used for device-to-device (D2D) communications;

transmitting, to a second UE, a second message comprising a second resource pool, wherein the second resource pool includes a subset of the plurality of radio resources of the first resource pool to be used by the second UE for sending a D2D transmission to the first UE, wherein the first UE is within a network coverage and the second UE is outside of the network coverage; and

receiving, from the second UE, a D2D transmission using at least one radio resource from the second resource pool.

6. The first UE of claim 5 , wherein the first UE receives information of the second resource pool from the base station via a radio resource control (RRC) message.

7. The first UE of claim 5 , wherein the second UE selects the at least one radio resource from the second resource pool.

8. The first UE of claim 7 , wherein the second UE operates in an autonomous selection mode.

9. One or more non-transitory computer-readable media storing computer instructions, that when executed by one or more processors, cause a first user equipment (UE) to perform operations comprising:

receiving, from a base station, a first message comprising a first resource pool, wherein the first resource pool includes a plurality of radio resources to be used for device-to-device (D2D) communications;

transmitting, from the first UE to a second UE, a second message comprising a second resource pool, wherein the second resource pool includes a subset of the plurality of radio resources of the first resource pool to be used by the second UE for sending a D2D transmission to the first UE, wherein the first UE is within a network coverage and the second UE is outside of the network coverage; and

receiving, at the first UE from the second UE, a D2D transmission using at least one radio resource from the second resource pool.

10. The one or more non-transitory computer-readable media of claim 9 , wherein the first UE receives information of the second resource pool from the base station via a radio resource control (RRC) message.

11. The one or more non-transitory computer-readable media of claim 9 , wherein the second UE selects the at least one radio resource from the second resource pool.

12. The one or more non-transitory computer-readable media of claim 11 , wherein the second UE operates in an autonomous selection mode.
