Abstract

Methods and apparatus to announce channel capabilities in wireless communication systems are discussed herein. An example first wireless communication device includes a channel support identifier to determine wireless communication channels supported by the wireless communication device, a channel capability field generator to generate a listing of the supported wireless communication channels, a channel capability field inserter to insert the listing into a Capabilities element transmitted to a second wireless communication device.

First claim

What is claimed is:

1. A first wireless communication device comprising:
a channel capabilities receiver to receive a first indication of first wireless communication channels supported by a second wireless communication device, the first indication including an operating mode element to indicate whether A) the first wireless communication device is limited to using the first wireless communication channels identified in the first indication when communicating with a third wireless communication device or B) the first wireless communication device may utilize wireless communication channels other than the first wireless communication channels when communicating with the third wireless communication device,
a memory to store a second indication of second wireless communication channels supported by the first wireless communication device;
a channel support identifier to determine ones of the second wireless communication channels supported by the first wireless communication device based on the first indication including the operating mode element and the second indication;
a channel capability field generator to generate a listing of the supported wireless communication channels;
a channel capability field inserter to insert the listing into an Extended Directional Multigigabit (EDMG) Capabilities element; and
a wireless transmitter to transmit the Capabilities element to the third wireless communication device.

2. The first wireless communication device as defined in claim 1 , wherein the second wireless communication channels are millimeter wave wireless communication channels.

3. The first wireless communication device as defined in claim 1 , wherein the listing of the supported wireless communication channels includes a first field identifying a number of supported wireless communication channels and second fields identifying the supported wireless communication channels.

4. The first wireless communication device as defined in claim 1 , further including a channel capabilities receiver to receive a third indication of wireless communication channels supported by the third wireless communication device.

5. The first wireless communication device as defined in claim 4 , wherein the first indication is sent in an EDMG Capabilities element.

6. The first wireless communication device as defined in claim 4 , further including a channel controller to select a wireless communication channel for communication that is included in the listing and the first indication.

7. The first wireless communication device as defined in claim 6 , wherein the first indication identifies wireless communication channels supported by a network infrastructure.

8. The first wireless communication device as defined in claim 7 , wherein the first indication is transmitted in an EDMG Operation element by a central device.

9. A method to announce channel capabilities in a wireless communication system, the method comprising:
receiving, by executing an instruction with a processor of a first wireless communication device, a first indication of first wireless communication channels supported by a second wireless communication device, the first indication including an operating mode element to indicate whether A) the first wireless communication device is limited to using the first wireless communication channels identified in the first indication when communicating with a third wireless communication device or B) the first wireless communication device may utilize wireless communication channels other than the first wireless communication channels when communicating with the third wireless communication device;
determining, by executing an instruction with the processor, second wireless communication channels supported by the first wireless communication device;
generating, by executing an instruction with the processor a listing of ones of the supported wireless communication channels based on the first indication including the operating mode element and the second wireless communication channels; and
inserting, by executing an instruction with the processor, the listing into an Extended Directional Multigigabit (EDMG) Capabilities element transmitted to a second third wireless communication device.

10. The method as defined in claim 9 , wherein the second wireless communication channels are millimeter wave wireless communication channels.

11. The method as defined in claim 9 , wherein the listing of the supported wireless communication channels includes a first field identifying a number of supported wireless communication channels and second fields identifying the supported wireless communication channels.

12. The method as defined in claim 9 , further including receiving a second indication of wireless communication channels supported by the second third wireless communication device.

13. The method as defined in claim 12 , wherein the second indication is sent in an EDMG Capabilities element.

14. The method as defined in claim 12 , further including selecting a wireless communication channel for communication that is included in the listing and the second indication.

15. The method as defined in claim 12 , wherein the first indication identifies wireless communication channels supported by a network infrastructure.

16. The method as defined in claim 15 , wherein the first indication is transmitted in an EDMG Operation element by a central device.

17. A tangible non-transitory computer readable storage medium comprising instructions that, when executed, cause a first wireless communication device to:
receive a first indication of first wireless communication channels supported by a second wireless communication device, the first indication including an operating mode element to indicate whether A) the first wireless communication device is limited to using the first wireless communication channels identified in the first indication when communicating with a third wireless communication device or B) the first wireless communication device may utilize wireless communication channels other than the first wireless communication channels when communicating with the third wireless communication device;
determine second wireless communication channels supported by the first wireless communication device;
generate a listing of ones of the supported wireless communication channels based on the first indication including the operating mode element and the second wireless communication channels; and
insert the listing into an Extended Directional Multigigabit (EDMG) Capabilities element transmitted to a second third wireless communication device.

18. The tangible non-transitory computer readable storage medium as defined in claim 17 , wherein the second wireless communication channels are millimeter wave wireless communication channels.

19. The tangible non-transitory computer readable storage medium as defined in claim 17 , wherein the listing of the supported wireless communication channels includes a first field identifying a number of supported wireless communication channels and second fields identifying the supported wireless communication channels.

20. The tangible non-transitory computer readable storage medium as defined in claim 17 , wherein the instructions, when executed, cause the first wireless communication device to receive a second indication of wireless communication channels supported by the third wireless communication device.
