PROCEDURES FOR HIGH EFFICIENCY ACKNOWLEDGEMENT TRANSMISSION
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.
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.
