Abstract

A system comprising a first wireless device which comprises a first group owner intent determination unit. The first group owner intent determination unit is configured to determine a group owner intent value of the first wireless device based on: whether the first wireless device is configured to access a coexisting wireless network, the power remaining in the first wireless device at the time the group owner intent value determination is made, whether the first wireless device is a group owner in another peer to peer group, a received signal strength indication of the first wireless device, and/or whether the first wireless device is required to perform a cross-connection between an infrastructure basic service set and a peer to peer group.

The wireless device of claim 1, wherein the group owner intent determination unit is further configured to determine the value of the wireless device which is used to determine a group owner in a peer to peer group based on whether the wireless device is a group owner in another peer to peer group.

4. The wireless device of claim 1, wherein the group owner intent determination unit value is further configured to determine the value of the wireless device which is used to determine a group owner in a peer to peer group based on a received signal strength indication of the wireless device.

5. A method, comprising:

identifying, by a wireless device, whether the wireless device is required to perform a cross-connection between an infrastructure basic service set and a peer to peer group;

identifying, by the wireless device, whether the wireless device is configured to access a coexisting wireless network;

determining, by the wireless device, a group owner intent value of the wireless device based on whether the wireless device is required to perform a cross-connection between an infrastructure basic service set and a peer to peer group and based on whether the wireless device is configured to access a coexisting wireless network.

6. The method of claim 5, wherein the determining the group owner intent value based on whether the wireless device is required to perform a cross-connection between an infrastructure basic service set and a peer to peer group comprises:

setting the group owner intent value to a maximum value based on the wireless device being required to perform a cross-connection between an infrastructure basic service set and the peer to peer group.

7. The method of claim 5, wherein the determining the group owner intent value based on whether the wireless device is configured to access a coexisting wireless network comprises:

determining, by the wireless device, the group owner intent value based on the power remaining in the wireless device at the time the group owner intent value determination is made in response to the wireless device not being configured to access a coexisting wireless network.

8. The method of claim 7, wherein the determining the group owner intent value based on the available power remaining in the wireless device at the time the group owner intent value determination is made comprises:

setting the group owner intent value to a maximum value based on the power of the wireless device being greater than a first threshold level;

setting the group owner intent value to a minimum value based on the power of the wireless device being less than a second threshold level; and

setting the group owner intent value to a value based on a received signal strength indication of the wireless device based on the power of the wireless device being less than or equal to the first threshold level and greater than or equal to the second threshold level.

9. The method of claim 5, wherein the determining the group owner intent value based on whether the wireless device is configured to access a coexisting wireless network comprises:

determining, by the wireless device, the group owner intent value based on whether the wireless device is a group owner in another peer to peer group in response to the wireless device being configured to access a coexisting wireless network.

10. The method of claim 9, wherein the determining the group owner intent value based on whether the wireless device is a group owner in another peer to peer group comprises:

identifying, by the wireless device, whether the wireless device is a group owner in another peer to peer group;

determining, by the wireless device, the group owner intent value based on the power remaining in the wireless device at the time the group owner intent value determination is made in response to the wireless device being configured to be the group owner in another peer to peer group.

11. The method of claim 10, wherein the determining the group owner intent value based on the available power remaining in the wireless device at the time the group owner intent value determination is made comprises:

setting the group owner intent value to a maximum value based on the power of the wireless device being greater than a first threshold level;

setting the group owner intent value to a minimum value based on the power of the wireless device being less than a second threshold level; and

setting the group owner intent value to a value based on a received signal strength indication of the wireless device based on the power of the wireless device being less than or equal to the first threshold level and greater than or equal to the second threshold level.

12. The method of claim 9, wherein the determining the group owner intent value based on whether the wireless device is a group owner in another peer to peer group comprises:

identifying, by the wireless device, whether the wireless device is a group owner in another peer to peer group;

determining, by the wireless device, the group owner intent value based on the power remaining in the wireless device at the time the group owner intent value determination is made in response to the wireless device being configured to not be the group owner in another peer to peer group.

13. The method of claim 12, wherein the determining the group owner intent value based on the available power remaining in the wireless device at the time the group owner intent value determination is made comprises:

setting the group owner intent value to a value based on an offset of a received signal strength indication of the wireless device based on the power of the wireless device being greater than a first threshold level;

setting the group owner intent value to a minimum value based on the power of the wireless device being less than a second threshold level; and

setting the group owner intent value to a value based on a received signal strength indication of the wireless device based on the power of the wireless device being less than or equal to the first threshold level and greater than or equal to the second threshold level.

14. A system, comprising:

a first wireless device comprising a first group owner intent determination unit,

wherein the first group owner intent determination unit is configured to determine a group owner intent value of the first wireless device based on;

whether the first wireless device is configured to access a coexisting wireless network, the power remaining in the first wireless device at the time the group owner intent value determination is made, whether the first wireless device is a group owner in a peer to peer group, or a received signal strength indication of the first wireless device.

15. The system of claim 14, wherein the first group owner intent determination unit is further configured to determine the group owner intent value of the first wireless device based on whether the first wireless device is required to perform a cross-connection between an infrastructure basic service set and a peer to peer group.

16. The system of claim 15, further comprising a second wireless device comprising a second group owner intent determination unit,

wherein the first and second wireless devices are configured to form a peer to peer group with each other.

17. The system of claim 16, wherein the first wireless device is configured to enter into a group owner negotiation with the second wireless device.
