Abstract

Various disclosed embodiments include methods and apparatus for inter-cell coordination for a device-to-device communication resource allocation. A method includes allocating, at a first base station, a device-to-device (D2D) communication resource from a pool of communication resources to a first electronic device controlled by the first base station, wherein the first electronic device is within a D2D communication group. The method also includes, in response to a second electronic device within the D2D communication group being controlled by a second base station, transmitting, by the first base station, information corresponding to the D2D communication resource allocation to the second base station.

Claims

1. A method comprising:

receiving, by a second base station, information corresponding to a device-to-device (D2D) communication resource allocation from a first pool of D2D communication resources to a first electronic device controlled by a first base station, wherein the first pool of D2D communication resources is reserved for D2D communication within a D2D communication group that includes the first electronic device, a second electronic device, and a third electronic device, and each electronic device of the D2D communication group communicates with each of the other electronic devices of the D2D communication group using the first pool of D2D communication resources;

receiving, by the second base station, information indicating a change to the first pool of D2D communication resources for the D2D communication group from the first base station;

transmitting, by the second base station, information corresponding to the changed first pool of D2D communication resources to the second electronic device in response to receiving the information indicating the change to the first pool of D2D communication resources from the first base station;

receiving, by the second base station, information indicating a change to a second pool of D2D communication resources from a third base station that controls the third electronic device within the D2D communication group; and

transmitting, by the second base station, information corresponding to the changed second pool of D2D communication resources to the second electronic device.

2. The method in accordance with claim 1, wherein the information corresponding to the changed first pool of D2D communication resources and the information corresponding to the changed second pool of D2D communication resources is combined prior to transmission to the second electronic device.

3. The method in accordance with claim 1, further comprising:

transmitting, by the second base station, the information corresponding to the changed first pool of D2D communication resources to the first base station.

4. A second base station comprising:

a processor; and

a non-transitory computer readable storage medium storing programming for execution by the processor, the programming including instructions to;

receive information corresponding to a device-to-device (D2D) communication resource allocation from a first pool of D2D communication resources to a first electronic device controlled by a first base station, wherein the first pool of D2D communication resources is reserved for D2D communication within a D2D communication group that includes the first electronic device, a second electronic device, and a third electronic device, and each electronic device of the D2D communication group communicates with each of the other electronic devices of the D2D communication group using the first pool of D2D communication resources;

receive information indicating a change to the first pool of D2D communication resources for the D2D communication group from the first base station;

transmit information corresponding to the changed first pool of D2D communication resources to the second electronic device in response to receiving the information indicating the change to the first pool of D2D communication resources from the first base station;

receive information indicating a change to a second pool of D2D communication resources from a third base station that controls the third electronic device within the D2D communication group; and

transmit information corresponding to the changed second pool of D2D communication resources to the second electronic device.

5. The second base station of claim 4, wherein the information corresponding to the changed first pool of D2D communication resources and the information corresponding to the changed second pool of D2D communication resources is combined prior to transmission to the second electronic device.

6. The second base station of claim 4, wherein the programming further includes instructions to:

transmit the information corresponding to the changed first pool of D2D communication resources to the first base station.
