8. The wireless communication device of claim 7 , wherein the one or more resource blocks includes a code sequence associated with the first resource unit in a frequency domain.

9. The wireless communication device of claim 1 , further comprising:

a transceiver in communication with the at least one processor, the transceiver being configured to transmit and receive wireless signals; and

one or more antennas coupled to the transceiver.

10. A non-transitory computer-readable medium storing computer-executable instructions which when executed by one or more processors result in performing operations comprising:

identifying a trigger frame received from an access point on a communication channel;

causing to transmit a High Efficiency Long Training Field (HE-LTF) in response to the trigger frame wherein the HE-LTF corresponds to a power save poll (PS-Poll);

identifying a multiuser acknowledgment received from the access point;

identifying buffered data received from the access point during a downlink multiuser delivery phase; and

causing to transmit the multiuser acknowledgment in response to receiving the buffered data.

11. The non-transitory computer-readable medium of claim 10 , further comprising computer-executable instructions which when executed by the one or more processors results in performing operations comprising:

encoding a 1-bit PS-Poll bit in four HE-LTFs.

12. The non-transitory computer-readable medium of claim 11 , wherein the 1-bit PS-Poll bit corresponds to a notification that the non-transitory computer-readable medium is not in a power save state.

13. The non-transitory computer-readable medium of claim 11 , wherein the 1-bit PS-Poll bit is sent to the access point using a spatial stream and resource unit.

14. The non-transitory computer-readable medium of claim 11 , wherein the 1-bit PS-Poll bit is sent in a frame that includes a physical layer (PHY) preamble.

15. The non-transitory computer-readable medium of claim 10 , wherein the HE-LTF includes one or more resource blocks, and the one or more resource blocks are identified by one or more resource block identifications (RBIDs).

16. The non-transitory computer-readable medium of claim 15 , wherein the one or more resource blocks includes a code sequence associated with a first resource unit in a frequency domain.

17. The non-transitory computer-readable medium of claim 13 , wherein the spatial stream corresponds to a line from a P-matrix.

18. A method comprising:

identifying a trigger frame received from an access point on a communication channel;

causing to transmit a High Efficiency Long Training Field (HE-LTF) in response to the trigger frame wherein the HE-LTF corresponds to a power save poll (PS-Poll);

identifying a multiuser acknowledgment received from the access point;

identifying buffered data received from the access point during a downlink multiuser delivery phase; and

causing to transmit the multiuser acknowledgment in response to receiving buffered data.

19. The method of claim 18 , further comprising:

encoding a 1-bit PS-Poll bit in four HE-LTFs.
