Abstract

This disclosure describes systems, methods, and devices related to allocating non-continuous resource units (RUs). A device may determine a non-continuous RU allocation for one or more devices in a 80 MHz bandwidth including four 20 MHz channels, the non-continuous RU allocation including disabled tones of a 20 MHz channel of the four 20 MHz channels, and the disabled tones being a subset of tones within the 20 MHz channel. The device may determine a high efficiency wireless frame comprising an indication of the non-continuous RU allocation. The device may send the high efficiency wireless frame to one or more multiple devices.

First claim

What is claimed is:

1. An apparatus for allocating frequency resources, the apparatus comprising processing circuitry coupled to storage, the processing circuitry configured to execute instructions to:
identify a first resource unit in a communication channel, the first resource unit consisting of a first number of tones;
identify a second resource unit in the communication channel, the second resource unit consisting of a second number of tones different than the first number of tones;
generate an extremely high throughput frame comprising an indication that a third resource unit is allocated to a station device, the third resource unit allocating only the first resource unit and the second resource unit non-contiguously; and
transmit the extremely high throughput frame.

2. The apparatus of claim 1 , wherein the first number of tones is 242 tones.

3. The apparatus of claim 1 , wherein the second number of tones is 484 tones.

4. The apparatus of claim 1 , wherein a fourth resource unit is between the first resource unit and the second resource unit in the communication channel, the fourth resource unit consisting of a third number of tones, wherein the third number of tones is 242 tones, and wherein the indication that the third resource unit is allocated to the station device comprises an indication that the fourth resource unit is not allocated to any station device.

5. The apparatus of claim 1 , wherein the indication that the third resource unit is allocated to the station device comprises an indication that a fourth resource unit in the communication channel is punctured.

6. The apparatus of claim 1 , further comprising a transceiver configured to transmit and receive wireless signals, wherein the wireless signals comprise the extremely high throughput frame.

7. The apparatus of claim 6 , further comprising an antenna coupled to the transceiver.

8. The apparatus of claim 1 , wherein the first number of tones comprises 242 tones.

9. The apparatus of claim 1 , wherein the first number of tones is 242 tones and wherein the second number of tones is 484 tones.

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, by an access point device, a first resource unit in a communication channel, the first resource unit consisting of a first number of tones;
identifying, by the access point device, a second resource unit in the communication channel, the second resource unit consisting of a second number of tones different than the first number of tones;
generating, by the access point device, an extremely high throughput frame comprising an indication that a third resource unit is allocated to a station device, the third resource unit allocating only the first resource unit and the second resource unit non-contiguously; and
transmitting, by the access point device, the extremely high throughput frame.

11. The non-transitory computer-readable medium of claim 10 , wherein the first number of tones is 242 tones.

12. The non-transitory computer-readable medium of claim 10 , wherein the second number of tones is 484 tones.

13. The non-transitory computer-readable medium of claim 10 , wherein the indication that the third resource unit is allocated to the station device comprises an indication that a fourth resource unit in the communication channel is punctured.

14. A method comprising:
identifying, by processing circuitry of an access point device, a first resource unit in a communication channel, the first resource unit consisting of a first number of tones;
identifying, by the processing circuitry, a second resource unit in the communication channel, the second resource unit consisting of a second number of tones different than the first number of tones;
generating, by the processing circuitry, an extremely high throughput frame comprising an indication that a third resource unit is allocated to a station device, the third resource unit allocating only the first resource unit and the second resource unit non-contiguously; and
transmitting, by the processing circuitry, the extremely high throughput frame.

15. The method of claim 14 , wherein the first number of tones is 242 tones and wherein the second number of tones is 484 tones.

16. The method of claim 14 , wherein a fourth resource unit is between the first resource unit and the second resource unit in the communication channel, the fourth resource unit consisting of a third number of tones, wherein the third number of tones is 242 tones, and wherein the indication that the third resource unit is allocated to the station device comprises an indication that the fourth resource unit is not allocated to any station device.

17. The method of claim 14 , wherein the indication that the third resource unit is allocated to the station device comprises an indication that a fourth resource unit in the communication channel is punctured.
