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. An apparatus comprising:

a storage device having instructions; and

a processor coupled with the storage device and configured to execute the instructions to

receive, in accordance with a first wireless communication protocol from an access point (AP) of an infrastructure based wireless network, a probe response frame including an information element, the information element indicating an allocation of one or more wireless channels for communications, in accordance with a second wireless communication protocol, among a plurality of wireless devices of a non-infrastructure based wireless network, the plurality of wireless devices including the apparatus and the second wireless communication protocol being different than the first wireless communication protocol; and

select a wireless channel of the one or more wireless channels for communication, in accordance with the second wireless communication protocol, with at least one wireless device of the plurality of wireless devices using the selected wireless channel.

2. The apparatus of claim 1, wherein the processor is further configured to execute the instructions to transmit, in accordance with the second wireless communication protocol, information identifying the allocation of the one or more wireless channels to one or more wireless devices of the plurality of wireless devices.

3. The apparatus of claim 1, wherein the processor is further configured to execute the instructions to communicate, in accordance with the second wireless communication protocol, with at least one wireless device of the plurality of wireless devices using the selected wireless channel.

4. The apparatus of claim 1, wherein the processor is further configured to execute the instructions to communicate with the AP on another wireless channel that is different from the one or more wireless channels.

5. The apparatus of claim 1, wherein:

the information element is a first information element;

the one or more wireless channels are one or more first wireless channels;

the plurality of wireless devices is a first plurality of wireless devices; and

the processor is further configured to receive, in accordance with the first wireless communication protocol, 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 by a second plurality of wireless devices configured to communicate within the infrastructure based wireless network in accordance with the first wireless communication protocol, the second plurality of wireless devices including the apparatus.

6. The apparatus of claim 5, wherein the secondary networking functions include a paging function, a parking function, or a roaming function.

7. The apparatus of claim 1, wherein the apparatus serves as an Access Point (AP) of the non-infrastructure based wireless network.

8. The apparatus of claim 7, wherein the processor is further configured to execute the instructions to establish the non-infrastructure based wireless network based on the allocation of the one or more wireless channels.

9. The apparatus of claim 1, wherein the non-infrastructure based wireless network is a peer-to-peer network, an independent basic service set (IBSS) network, or a personal area network.

10. The apparatus of claim 9, wherein the infrastructure based wireless network is a wireless local area network (WLAN), a wireless metropolitan area network (WMAN), or a worldwide interoperability for microwave access (WiMAX) network.

11. The apparatus of claim 10, wherein the infrastructure based wireless network is a WLAN and the non-infrastructure based wireless network is a peer-to-peer network or personal area network.

12. The apparatus of claim 1, wherein the first wireless communication protocol and the second wireless communication protocol are in accordance with a common wireless communication standard.

13. The apparatus of claim 1, wherein the information element includes a use mode field to indicate a purpose for which the allocation of one or more wireless channels is intended to be used.
