Abstract

Systems, methods, and instrumentalities are disclosed for range extension, basic service set (BSS) color labeling, and multi-user (MU) fragmentation and control in WLANs. A range extension notification/enablement scheme, a clear channel assessment (CCA), a headroom indication, and/or power scaling may be provided for a range extension mode. BSS color may be provided for multiple-BSSs under an access point (AP). Uplink (UL) transmission may be provided with different fragmentation capabilities. A high-efficiency (HE) trigger-based UL NDP physical layer convergence protocol (PLCP) protocol data unit (PPDU) frame may be provided. A station (STA) may receive a trigger frame comprising a null data packet (NDP) indication and a trigger type. The STA may determine that the STA is an intended recipient of the trigger frame. The STA may prepare an NDP PPDU for a control frame and/or a management frame based on the trigger type.

Claims (26)

1. A station (STA) comprising:

a transceiver; and

a processor, wherein the transceiver and the processor are configured to:

receive, from an access point (AP), a trigger frame including a null data packet (NDP) trigger type indication and an indication of a Basic Service Set (BSS) Identifier (BSSID) associated with two or more BSSs associated with the AP, wherein the STA is associated with one of the two or more BSSs; and

transmit, to the AP in response to the received NDP trigger type indication, a first NDP frame carrying short UL feedback information including at least a feedback report.

2. The STA of claim 1 , wherein the NDP trigger type indication is in a common information field of the trigger frame.

3. The STA of claim 1 , wherein the NDP trigger type indication is in a user-specific information field of the trigger frame.

4. The STA of claim 1 , wherein the first NDP frame further includes an uplink (UL) resource request.

5. The STA of claim 4 , wherein the UL resource request is an UL transmission opportunity (TXOP) request.

6. The STA of claim 1 , wherein the first NDP frame is a small control frame or a management frame.

7. The STA of claim 1 , wherein the feedback report is an (uplink) UL traffic report.

8. The STA of claim 1 configured as a high-efficiency (HE) STA.

9. The STA of claim 1 , wherein:

the transceiver and the processor are further configured to determine transmission parameters based at least in part on the trigger frame.

10. A method performed by a station (STA), the method comprising:

receiving, from an access point (AP), a trigger frame including a null data packet (NDP) trigger type indication and an indication of a Basic Service Set (BSS) Identifier (BSSID) associated with two or more BSSs associated with the AP, wherein the STA is associated with one of the two or more BSSs; and

transmitting, to the AP in response to the received NDP trigger type indication, a first NDP frame carrying short UL feedback information including at least a feedback report.

11. The method of claim 10 , wherein the NDP trigger type indication is in a common information field of the trigger frame.

12. The method of claim 10 , wherein the NDP trigger type indication is in a user-specific information field of the trigger frame.

13. The method of claim 10 , wherein the first NDP frame further includes an uplink (UL) resource request.

14. The method of claim 13 , wherein the UL resource request is an UL transmission opportunity (TXOP) request.

15. The method of claim 10 , wherein the first NDP frame is a small control frame or a management frame.

16. The method of claim 10 , wherein the feedback report is an (uplink) UL traffic report.

17. The method of claim 10 , wherein the STA is configured as a high-efficiency (HE) STA.

18. The method of claim 10 , further comprising:

determining transmission parameters based at least in part on the trigger frame.
