Abstract

A method for high efficiency (HE) acknowledgement transmission may be performed by a station (STA) in a wireless local area network (WLAN) system. The method may include receiving a downlink (DL) frame indicating a resource allocation for the STA to transmit an uplink (UL) transmission. It may further include transmitting an acknowledgement frame in a single-user (SU) transmission or multi-user (MU) transmission, where the acknowledgement frame includes an indication of an operation mode change.

Claims (30)

1 . A station (STA) comprising:

a transceiver, coupled to a baseband processor, a memory, a power source and an antenna;

the transceiver configured to:

receive a downlink (DL) frame indicating a resource allocation for the STA to transmit an uplink (UL) transmission; and

transmit an acknowledgement frame in a single-user (SU) transmission or multi-user (MU) transmission, wherein the acknowledgement frame includes an indication of an operation mode change.

2 . The STA of claim 1 , wherein the indication of an operation mode change includes a change in SU/MU orthogonal frequency division multiple access (OFDMA) capability.

3 . The STA of claim 1 , wherein the indication of an operation mode change includes a change in a number of spatial streams (Nss).

4 . The STA of claim 1 , wherein the indication of an operation mode change includes a change in an operation bandwidth.

5 . The STA of claim 1 , wherein the indication of an operation mode change includes a change in an operation resource block width.

6 . A method performed by a station (STA) comprising:

receiving a downlink (DL) frame indicating a resource allocation for the STA to transmit an uplink (UL) transmission; and

transmitting an acknowledgement frame in a single-user (SU) transmission or a multi-user (MU) transmission, wherein the acknowledgement frame includes an indication of an operation mode change.

7 . The method of claim 6 , wherein the indication of an operation mode change includes a change in SU/MU orthogonal frequency division multiple access (OFDMA) capability.

8 . The method of claim 6 , wherein the indication of an operation mode change includes a change in a number of spatial streams (Nss).

9 . The method of claim 6 , wherein the indication of an operation mode change includes a change in an operation bandwidth.

10 . The method of claim 6 , wherein the indication of an operation mode change includes a change in an operation resource block width.

11 . An access point (AP) comprising:

a transceiver, coupled to a baseband processor, a memory, a power source and an antenna;

the transceiver configured to:

transmit a downlink (DL) frame indicating resource allocation for the STA to transmit uplink (UL) transmissions; and

receive an acknowledgement frame in a single-user (SU) or multi-user (MU) transmission, wherein the acknowledgement frame includes an indication of an operation mode change.

12 . The AP of claim 11 , wherein the baseband processor is configured to adjust a resource allocation based on the operation mode change.

13 . The AP of claim 11 , wherein the baseband processor is configured to allocate a different number of resource blocks (RBs) and channel based on the operation mode change.

14 . The AP of claim 11 , wherein the baseband processor is configured to allocate a different number of spatial streams (Nss) based on the operation mode change.

15 . The AP of claim 11 , wherein the baseband processor is configured to change transmission/reception settings based on the operation mode change.

16 . The AP of claim 11 , wherein the baseband processor is configured to switch between single-user (SU) and multi-user (MU) transmission mode based on the operation mode change.

17 . The AP of claim 11 , wherein the indication of an operation mode change includes a change in SU/MU orthogonal frequency division multiple access (OFDMA) capability.

18 . The AP of claim 11 , wherein the indication of an operation mode change includes a change in a number of spatial streams (Nss).

19 . The AP of claim 11 , wherein the indication of an operation mode change includes a change in an operation bandwidth.

20 . The AP of claim 11 , wherein the indication of an operation mode change includes a change in an operation resource block width.
