Abstract

Embodiments of methods and apparatus for dynamic channel allocation are disclosed. In various embodiments, an access point (AP) of an infrastructure based wireless network may allocate one or more wireless channels to wireless devices of a non-infrastructure based wireless network. The allocated channels may be selected to reduce a likelihood of communications among the devices of the non-infrastructure based wireless network interfering with communications among the devices of the infrastructure based wireless network. Additional variants and embodiments may also be disclosed and claimed.

Claims

1. A method comprising:

selecting, by an access point (AP) of an infrastructure based wireless network, a first wireless channel for communications among a first plurality of wireless devices of a non-infrastructure based wireless network, the selecting of the first wireless channel being configured to reduce a likelihood that communications among the first plurality of wireless devices, in accordance with a first wireless communication protocol, interfere with communications among a second plurality of wireless devices of the infrastructure based wireless network in accordance with a second wireless communication protocol that is different from the first wireless communication protocol, the second plurality of wireless devices including the AP;

selecting, by the AP, a second wireless channel for secondary networking functions within the infrastructure based wireless network;

transmitting, in accordance with the second wireless communication protocol, by the AP to a wireless device of the first plurality of wireless devices, a first information element to communicate an allocation of the first wireless channel to the first plurality of wireless devices; and

transmitting, in accordance with the second wireless communication protocol, by the AP to the wireless device of the first plurality of wireless devices, a second information element to communicate an allocation of the second wireless channel to the first plurality of wireless devices for one or more secondary networking functions within the infrastructure based wireless network, wherein the one or more secondary networking functions include a paging function, a parking function, or a roaming function.

2. The method of claim 1, wherein the communications within the infrastructure based wireless network and the non-infrastructure based wireless network are in accordance with a common wireless communication standard.

3. The method of claim 1, wherein said selecting the first wireless channel comprises:

determining a likelihood of interference among each of a plurality of potential wireless channels and one or more wireless channels utilized by the second plurality of wireless devices; and

selecting the first wireless channel from the plurality of potential wireless channels based at least in part on said determining of the likelihood of interference.

4. The method of claim 1, wherein said transmitting the first or second information element further comprises:

transmitting a beacon frame that includes the first or second information element.

5. The method of claim 1, wherein said transmitting the first or second information element further comprises:

transmitting a probe response frame that includes the first or second information element.

6. The method of claim 1, wherein the first information element further includes an identification of a regulatory class associated with the selected first wireless channel.

7. The method of claim 1, wherein the first information element is further configured to communicate an allocation of a third wireless channel to the first plurality of wireless devices.

8. The method of claim 1, wherein the infrastructure based wireless network is a local area network.

9. The method of claim 8, wherein the non-infrastructure based wireless network is a personal area network.

20. The method of claim 1, wherein:

the first information element includes a first use mode field having a value to indicate that the first wireless channel is allocated for wireless communication within the non-infrastructure based wireless network; and

the second information element includes a second use mode field having a value to indicate that that the second channel is allocated for the one or more secondary networking functions within the infrastructure based wireless network.

21. The method of claim 1, wherein the first information element or the second information element includes a use mode field that indicates a purpose for which a selected wireless channel is intended to be used, wherein the use mode field is configured to have

a first value that indicates that a selected wireless channel is allocated for wireless communication within a personal area network,

a second value that indicates that a selected wireless channel is allocated for wireless communication within a peer-to-peer network,

a third value that indicates that a selected wireless channel is allocated for a paging function,

a fourth value that indicates that a selected wireless channel is allocated for a roaming function, and

a fifth value that indicates that a selected wireless channel is allocated for a parking function.

10. A method comprising:

receiving in accordance with a second wireless communication protocol, at a wireless device of a first plurality of wireless devices of a non-infrastructure based wireless network, a first information element from an access point (AP) of an infrastructure based wireless network, the first information element communicating an allocation by the AP of one or more first wireless channels for communications among the first plurality of wireless devices that reduces a likelihood that communications among the first plurality of wireless devices, in accordance with a first wireless communication protocol, interfere with communications among a second plurality of devices of the infrastructure based wireless network in accordance with the second wireless communication protocol, the first wireless communication protocol being different from the second wireless communication protocol;

selecting, by the wireless device, a first wireless channel from the one or more first wireless channels;

communicating, by the wireless device, with at least one wireless device of the first plurality of wireless devices on the first wireless channel; and

receiving in accordance with the second wireless communication protocol, at the wireless device of the first plurality of wireless devices of the non-infrastructure based wireless network, a second information element from the AP of the infrastructure based wireless network, the second information element communicating an allocation by the AP of one or more second wireless channels for one or more secondary networking functions within the infrastructure based wireless network, wherein the one or more secondary networking functions include a paging function, a parking function, or a roaming function.

11. The method of claim 10, further comprising:

communicating, by the wireless device, with the AP on another wireless channel, which is different from the one or more first wireless channels.

12. The method of claim 10, wherein communications within the infrastructure based wireless network and the non-infrastructure based wireless network are in accordance with a common wireless communication standard.

13. The method of claim 10, wherein the non-infrastructure based network is a peer-to-peer network.

14. The method of claim 10, wherein the non-infrastructure based network is a personal area network.

15. An apparatus comprising:

a wireless interface; and

a selector coupled to the wireless interface and configured to

allocate one or more first wireless channels for communications among a first plurality of wireless devices of a non-infrastructure based wireless network to reduce a likelihood that communications among the first plurality of wireless devices, in accordance with a first wireless communication protocol, interfere with communications among a second plurality of wireless devices of an infrastructure based wireless network in accordance with a second wireless communication protocol that is different from the first wireless communication protocol, the second plurality of wireless devices including the apparatus,

allocate a second wireless channel for one or more secondary networking functions within the infrastructure based wireless network,

transmit, in accordance with the second wireless communication protocol via the wireless interface, a first information element to communicate the allocation of the one or more first wireless channels to a wireless device of the first plurality of wireless devices, and
