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.

First claim

What is claimed is:

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.
