Abstract

A method and an apparatus for control information resource allocation for device to device (D2D) communications. The method includes receiving a network allocation of resource configuration to the UE. The method further includes selecting a set of resources from the network allocation of resource configuration based on a priority rule. The method also includes transmitting the selected set of resources to one or more other UEs.

Claims

1. A user equipment (UE) comprising:

a transceiver; and

one or more processors operably connected to the transceiver, the one or more processors configured to;

receive, via the transceiver, a network allocation of resource configurations from a base station;

select a set of resources from the network allocation of resource configurations based on a priority rule; and

transmit, via the transceiver, the selected set of resources to one or more other UEs.

2. The UE of claim 1, wherein the priority rule comprises a priority indicator provided by a higher layer signaling for each of a plurality of resource pools.

3. The UE of claim 1, wherein the priority rule comprises a priority indicator implicitly carried by an identification for each of a plurality of resource pools.

4. The UE of claim 1, wherein the priority rule comprises a priority indication based on a type of data transmission associated with each of a plurality of resource pools.

5. The UE of claim 1, wherein the one or more processors are further configured to:

receive, via the transceiver, a message for UE-to-network relay selection;

perform a feasibility measurement; and

transmit, via the transceiver, the feasibility measurement to the base station (BS).

6. The UE of claim 1, wherein the one or more processors are further configured to perform a relay reselection procedure after a given relay period.

7. The UE of claim 1, wherein the one or more processors are further configured to receive, via the transceiver, a message to perform a relay operation given an indicated relay configuration.

8. A base station (BS) configured to communicate with a plurality of UEs, the base station comprising:

a transceiver; and

one or more processors operably connected to the memory, the one or more processors configured to;

configure a network allocation of resource configurations; and

transmit, via the transceiver, the network allocation of resource configurations to a user equipment (UE).

9. The BS of claim 8, wherein the priority rules comprises a priority indicator provided by a higher layer signaling for each of a plurality of resource pools.

10. The BS of claim 8, wherein the priority rule comprises a priority indicator implicitly carried by an identification for each of a plurality of resource pools.

11. The BS of claim 8, wherein the priority rule comprises a priority indication based on a type of data transmission associated with each of a plurality of resource pools.

12. The BS of claim 8, wherein the one or more processors are further configured to:

transmit, via the transceiver, a message for UE-to-network relay selection to authorized UEs;

receive, via the transceiver, a feasibility measurement from each of the authorized UEs; and

select, via the transceiver, a candidate UE based on the feasibility measurement received from the authorized UEs.

13. The BS of claim 8, wherein the one or more processors are further configured to perform a relay reselection procedure after a given relay period.

14. The BS of claim 8, wherein the one or more processors are further configured to transmit, via the transceiver, a message to perform a relay operation given the indicated relay configuration.

15. A method for operating a user equipment (UE), the method comprising:

receiving a network allocation of resource configuration to the UE;

selecting a set of resources from the network allocation of resource configuration based on a priority rule; and

transmitting the selected set of resources to one or more other UEs.

16. The method of claim 15, wherein the priority rule comprises a priority indicator is provided by a higher layer signaling for each of a plurality of resource pools.

17. The method of claim 15, wherein the priority rule comprises a priority indicator is implicitly carried by an identification for each of a plurality of resource pools.

18. The method of claim 15, wherein the priority rule comprises a priority indication based on a type of data transmission associated with each of a plurality of resource pools.

19. The method of claim 15, further comprising:

receiving a message for UE-to-network relay selection;

performing a feasibility measurement; and

transmitting the feasibility measurement to the base station (BS).

20. The method of claim 15, further comprising performing a relay reselection procedure after a given relay period.
