Abstract

A method of operating a first wireless device includes sending a first message including a first intent to be a group owner and a value to a second wireless device. In addition, the method includes receiving a second message including a second intent to be the group owner from the second wireless device. Furthermore, the method includes determining which of the first wireless device or the second wireless device should be the group owner based on the first intent, the second intent, and the value.

Claims

1. A method of operating a first wireless device, comprising:

sending a first message including a first intent to be a group owner and a value to a second wireless device;

receiving a second message including a second intent to be the group owner from the second wireless device; and

determining which of the first wireless device or the second wireless device should be the group owner based on the first intent, the second intent, and the value.

2. The method of claim 1, wherein the value is a tie breaker value used to determine which of the first wireless device or the second wireless device should be the group owner when the first intent is equal to the second intent.

3. The method of claim 2, wherein the tie breaker value is used to determine which of the first wireless device or the second wireless device should be the group owner when the first intent and the second intent both indicate a lack of necessity of being the group owner.

4. The method of claim 1, wherein the first message includes the value, the second message includes a second value determined based on the value, and the determining which of the first wireless device or the second wireless device should be the group owner is only or also based on the second value.

5. The method of claim 4, wherein the value and the second value are each a bit, the second value is toggled from the value such that the second value is 1 when the value is 0 and the second value is 0 when the value is 1, and the determining which of the first wireless device or the second wireless device should be the group owner is based on which of the value or the second value is a 1.

6. The method of claim 1, wherein the first message is a group owner negotiation request and the second message is a group owner negotiation response.

7. The method of claim 1, wherein the value is a bit and the method further comprises setting the value to 0 or 1 evenly on average.

8. The method of claim 1, wherein the second message includes a second value toggled based on the value and the determining which of the first wireless device or the second wireless device should be the group owner comprises:

determining that the first wireless device is the group owner when the first intent is greater than the second intent;

determining that the second wireless device is the group owner when the second intent is greater than the first intent;

determining that neither the first wireless device nor the second wireless device should be the group owner when the first intent and the second intent are equal and both indicate a necessity to be the group owner;

determining that the first wireless device should be the group owner when the first intent and the second intent are equal and the value indicates the first wireless device should be the group owner; and

determining that the second wireless device should be the group owner when the first intent and the second intent are equal and the second value indicates the second wireless device should be the group owner.

9. An apparatus for wireless communication, comprising:

means for sending a first message including a first intent to be a group owner and a value to a second apparatus;

means for receiving a second message including a second intent to be the group owner from the second apparatus; and

means for determining which of the apparatus or the second apparatus should be the group owner based on the first intent, the second intent, and the value.

10. The apparatus of claim 9, wherein the value is a tie breaker value used to determine which of the apparatus or the second apparatus should be the group owner when the first intent is equal to the second intent.

11. The apparatus of claim 10, wherein the tie breaker value is used to determine which of the apparatus or the second apparatus should be the group owner when the first intent and the second intent both indicate a lack of necessity of being the group owner.

12. The apparatus of claim 9, wherein the first message includes the value, the second message includes a second value determined based on the value, and the means for determining which of the apparatus or the second apparatus should be the group owner is also based on the second value.

13. The apparatus of claim 12, wherein the value and the second value are each a bit, the second value is toggled from the value such that the second value is 1 when the value is 0 and the second value is 0 when the value is 1, and the means for determining which of the apparatus or the second apparatus should be the group owner is based on which of the value or the second value is a 1.

14. The apparatus of claim 9, wherein the first message is a group owner negotiation request and the second message is a group owner negotiation response.

15. The apparatus of claim 9, wherein the value is a bit and the apparatus further comprises means for setting the value to 0 or 1 evenly on average.

16. The apparatus of claim 9, wherein the second message includes a second value toggled based on the value and the means for determining which of the apparatus or the second apparatus should be the group owner comprises:

means for determining that the apparatus is the group owner when the first intent is greater than the second intent;

means for determining that the second apparatus is the group owner when the second intent is greater than the first intent;

means for determining that neither the apparatus nor the second apparatus should be the group owner when the first intent and the second intent are equal and both indicate a necessity to be the group owner;

means for determining that the apparatus should be the group owner when the first intent and the second intent are equal and the value indicates the apparatus should be the group owner; and

means for determining that the second apparatus should be the group owner when the first intent and the second intent are equal and the second value indicates the second apparatus should be the group owner.

17. A computer program product in a first wireless device, comprising:

a computer-readable medium comprising code for;

sending a first message including a first intent to be a group owner and a value to a second wireless device;

receiving a second message including a second intent to be the group owner from the second wireless device; and

determining which of the first wireless device or the second wireless device should be the group owner based on the first intent, the second intent, and the value.

18. The computer program product of claim 17, wherein the value is a tie breaker value used to determine which of the first wireless device or the second wireless device should be the group owner when the first intent is equal to the second intent.
