Abstract

An apparatus and method provides very high throughput (VHT) wireless local area network (WLAN) frequency reuse information reports and adjusts operation parameters based on the frequency reuse information reports.

Claims

1. A method for use in wireless communications, the method comprising:

providing very high throughput (VHT) wireless local area network (WLAN) frequency reuse information reports; and

adjusting operation parameters based on the frequency reuse information reports.

2. The method of claim 1, wherein the VHT frequency reuse is provided to a basic service set (BSS), where the BSS includes an access point (AP) and a plurality of wireless transmit/receive units (WTRUs).

3. The method of claim 1, wherein the VHT frequency reuse information is based on basic service sets (BSSs).

4. The method of claim 1, wherein the operation parameter comprises channel identities.

5. The method of claim 1, wherein the operation parameter comprises channel bandwidths.

6. The method of claim 1, wherein the operation parameter comprises channel usage patterns.

7. The method of claim 1, wherein the operation parameter comprises channel bandwidth usage patterns.

8. The method of claim 1, wherein the frequency reuse information report comprises signal transmission powers.

9. The method of claim 1, wherein the frequency reuse information report comprises traffic loads.

10. The method of claim 1, wherein the frequency reuse information report is broadcast by a WTRU.

11. The method of claim 1, wherein the frequency reuse information report is broadcast by an access point.

12. The method of claim 1, wherein the frequency reuse information report is comprised in a beacon.

13. The method of claim 1, wherein the frequency reuse information report is comprised in a management action frame or public action frame.

14. A wireless transmit/receive unit (WTRU) comprising:

receiving very high throughput (VHT) wireless local area network (WLAN) frequency reuse information reports; and

adjusting operation parameters based on the frequency reuse information reports.

15. The WTRU of claim 14, wherein the VHT frequency reuse information is based on basic service sets (BSSs).

16. The method of claim 14, wherein the operation parameter comprises channel identities.

17. The method of claim 14, wherein the operation parameter comprises channel bandwidths.

18. The method of claim 14, wherein the operation parameter comprises channel usage patterns.

19. The method of claim 14, wherein the operation parameter comprises channel bandwidth usage patterns.

20. The method of claim 14, wherein the frequency reuse information report comprises signal transmission powers.

21. A method for use in wireless communication comprising:

performing very high throughput (VHT) wireless local area network (WLAN) channel scanning.

22. A method for use in wireless communication, the method comprising:

performing very high throughput (VHT) wireless local area network (WLAN) channel scanning using a VHT channel scan request.
