OPTIMIZING WIRELESS NETWORK COMMUNICATIONS

1 . A device, comprising:

one or more processors; and

one or more memory devices storing program instructions that are executable by the one or more processors to:

select a frequency resource allocation index that allocates a first resource unit (RU) utilized in a narrow bandwidth transmission; and

set at second RU in the frequency resource allocation as non-allocated.

2 . The device of claim 1 , wherein the transmission comprises a high-efficiency signal field B (HE-SIG-B) communication.

3 . The device of claim 2 , wherein the HE-SIG-B communication comprises a HE-SIG-B 1 communication and a HE-SIG-B 2 communication, wherein the HE-SIG-B 2 communication allocates a 20 MHZ sub channel in instead of the HE-SIG-B 1 communication allocating the 20 MHZ sub channel.

4 . The device of claim 1 , wherein the allocated first RU comprises at least 26 tones.

5 . The device of claim 1 , wherein the non-allocated second RU comprises a plurality of non-allocated RUs.

6 . The device of claim 5 , wherein the plurality of non-allocated RUs are arranged contiguously in the frequency resource allocation to mitigate frequency domain interference.

7 . The device of claim 5 , wherein the plurality of non-allocated RUs are arranged non-contiguously in the frequency resource allocation to mitigate frequency domain interference.

8 . The device of claim 1 , further comprising a radio.

9 . The device of claim 8 , wherein the radio comprises one or more antennas.

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

selecting a frequency resource allocation index that allocates a first resource unit (RU) utilized in a narrow bandwidth transmission; and

causing to set a second RU in the frequency resource allocation as non-allocated.

11 . The medium of claim 10 , wherein the transmission comprises a high-efficiency signal field B (HE-SIG-B) communication.

12 . The medium of claim 11 , wherein the HE-SIG-B communication comprises a HE-SIG-B 1 communication and a HE-SIG-B 2 communication, wherein the HE-SIG-B 2 communication allocates a 20 MHZ sub channel in instead of the HE-SIG-B 1 communication allocating the 20 MHZ sub channel.

13 . The medium of claim 10 , wherein the allocated first RU comprises at least 26 tones.

14 . The medium of claim 10 , wherein the non-allocated second RU comprises a plurality of non-allocated RUs.

15 . The medium of claim 14 , wherein the plurality of non-allocated RUs are arranged contiguously in the frequency resource allocation index to mitigate frequency domain interference.

16 . The medium of claim 14 , wherein the plurality of non-allocated RUs are arranged non-contiguously in the frequency resource allocation index to mitigate frequency domain interference.

17 . A device, comprising:

one or more processors; and

one or more memory devices storing program instructions that are executable by the one or more processors to:

receive a stream index of a multiple-user multiple-input multiple-output (MU-MIMO) transmission, the stream index including a spatial stream indication for a station (STA) and an indication of a number of high-efficiency long training field (HE-LTF) symbols in a current PLCP Protocol Data Unit (PPDU).

18 . The device of claim 17 , further comprising a radio.

19 . The device of claim 18 , wherein the radio comprises one or more antennas.

20 . The device of claim 17 , wherein the indication of the number of HE-LTF symbols is optimized to save at least one signaling bit.

21 . The device of claim 20 , wherein the indication of the number of HE-LTF symbols is optimized by limiting a number of MU-MIMO user spatial streams to reduce signaling overhead.

22 . A computer-readable non-transitory storage medium that contains instructions, which when executed by one or more processors result in performing operations comprising:

receiving a stream index of a multiple-user multiple-input multiple-output (MU-MIMO) transmission, the stream index including a spatial stream indication for a station (STA) and an indication of a number of high-efficiency long training field (HE-LTF) symbols in a current PLCP Protocol Data Unit (PPDU).

23 . The medium of claim 22 , wherein the indication of the number of HE-LTF symbols is optimized to save at least one signaling bit.

24 . The medium of claim 23 , wherein the indication of the number of HE-LTF symbols is optimized by limiting a number of MU-MIMO user spatial streams to reduce signaling overhead.
