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. A device, the device comprising storage coupled to processing circuitry, the processing circuitry configured to:
determine a non-continuous resource unit allocation for a station device in a 80 MHz bandwidth, wherein the non-continuous resource unit allocation comprises an indication of a first resource unit allocated to the station device, the first resource unit being in the 80 MHz bandwidth and the indication indicating that the first resource unit combines a second resource unit in the 80 MHz bandwidth, a third resource unit in the 80 MHz bandwidth, and a fourth resource unit of punctured tones between the second resource unit and the third resource unit, the second resource unit having a different number of tones than the third resource unit;
generate a high efficiency wireless frame comprising the indication of the first resource unit allocated to the station device; and
cause to send the high efficiency wireless frame.

2. The device of claim 1 , wherein the first resource unit and the second resource unit are non-adjacent resource units in the 80 MHz bandwidth.

3. The device of claim 1 , wherein the indication of the first resource unit allocated to the station device is included in a high efficiency signal-B (HE-SIG-B) field of the high efficiency wireless frame, and wherein the HE-SIG-B field comprises multiple user information fields addressed to a first device of the one or more devices.

4. The device of claim 1 , further comprising a transceiver configured to transmit and receive wireless signals, wherein the wireless signals comprise the high efficiency wireless frame.

5. The device of claim 4 , further comprising an antenna coupled to the transceiver.

6. The device of claim 1 , wherein the second resource unit has 242 tones.

7. The device of claim 1 , wherein the third resource unit has 484 tones.

8. The device of claim 1 , wherein the fourth resource unit has 242 tones.

9. The device of claim 8 , wherein the non-continuous resource unit allocation indicates that the fourth resource unit is not allocated to any station device.

10. The device of claim 8 , wherein the non-continuous resource unit allocation indicates that the fourth resource unit is punctured.

11. A non-transitory computer-readable medium storing computer-executable instructions which when executed by one or more processors result in performing operations comprising:
identifying, at a station device, a high efficiency wireless frame received from an access point;
determining that the high efficiency wireless frame comprises an indication of a non-continuous resource allocation for one or more devices in a 80 MHz bandwidth, wherein the one or more devices comprise the station device; and
determining that the non-continuous resource allocation comprises an allocation of a first resource unit allocated to the station device, the first resource unit being in the 80 MHz bandwidth, and the indication indicating that the first resource unit combines a second resource unit in the 80 MHz bandwidth a third resource unit in the 80 MHz bandwidth, and a fourth resource unit of punctured tones between the second resource unit and the third resource unit, the second resource unit having a different number of tones than the third resource unit.

12. The non-transitory computer-readable medium of claim 11 , the operations further comprising determining two or more user information fields of the high efficiency wireless frame, wherein the two or more user information fields comprise an address associated with the station device, and wherein the indication of the non-continuous resource allocation comprises the two or more user information fields.

13. The non-transitory computer-readable medium of claim 11 , wherein the second resource unit and the third resource unit are non-adjacent resource units.

14. The non-transitory computer-readable medium of claim 11 , wherein the second resource unit has 242 tones.

15. The non-transitory computer-readable medium of claim 11 , wherein the third resource unit has 484 tones.

16. The non-transitory computer-readable medium of claim 11 , wherein the fourth resource unit has 242 tones.

17. The non-transitory computer-readable medium of claim 16 , wherein the non-continuous resource allocation indicates that the fourth resource unit is not allocated to any station device.

18. The non-transitory computer-readable medium of claim 16 , wherein the non-continuous resource allocation indicates that the fourth resource unit is punctured.

19. A method comprising:
determining, by processing circuitry of an access point, a non-continuous resource allocation for a station device in a 80 MHz bandwidth, wherein the non-continuous resource allocation comprises an indication of a first resource unit allocated to the station device, the first resource unit being in the 80 MHz bandwidth and the indication indicating that the first resource unit combines a second resource unit of the 80 MHz bandwidth, a third resource unit of the 80 MHz bandwidth, and a fourth resource unit of punctured tones between the second resource unit and the third resource unit, the second resource unit having a different number of tones than the third resource unit;
generating a high efficiency wireless frame comprising the indication of the first resource unit allocated to the station device non; and
causing to send the high efficiency wireless frame.

20. The method of claim 19 , wherein the second resource unit has 242 tones and the third resource unit has 484 tones.
