Abstract

Methods and systems may include processes by which the reliability and robustness of a wireless network may be improved. In some implementations, a method may include selecting at least two resource units to be used for communications to a single client device; and transmitting data in duplicate via each of the at least two resource units to the client device such that the client device is able to combine the data from each of the at least two resource units into a single instance of the data. In some implementations, a method may include obtaining notification of one or more ranges of frequencies corresponding to a set of resource units to be avoided in a spectrum of available frequencies, and allocating resource units to a set of client devices that covers the available frequencies while excluding the set of resource units to be avoided.

Claims (36)

1 . A method comprising:

obtaining notification of one or more ranges of frequencies corresponding to a 20 MHz resource unit to be avoided in a spectrum of available frequencies; and

allocating multiple resource units to a set of client devices that covers the available frequencies while excluding the one or more ranges of frequencies corresponding to the 20 MHz resource unit to be avoided, wherein allocating the multiple resource units comprises:

selecting at least two resource units outside of the 20 MHz resource unit to be used for communicating data to a single client device; and

assigning each remainder resource unit, outside of the at least two resource units and the 20 MHz resource unit, in either a multi-user multi-input multi-output (MU-MIMO) configuration, or a single-user multi-input multi-output (SU-MIMO) configuration.

2 . The method of claim 1 , wherein obtaining notification of the one or more ranges of frequencies is based on operations comprising:

monitoring the one or more ranges of frequencies for interference; and

detecting the interference for the one or more ranges of frequencies as above a threshold level of interference,

wherein the one or more ranges of frequencies are designated as to be avoided based on the interference being above the threshold.

3 . The method of claim 1 , wherein the at least two resource units, the 20 MHz resource unit, and the remainder resource units comprise an orthogonal frequency-division multiple access (OFDMA) frame.

4 . The method of claim 1 , the multiple resource units being for an 80 MHz transmission.

5 . The method of claim 4 , the 80 MHz transmission including a multiple user (MU) transmission.

6 . The method of claim 4 , the 80 MHz including a 494-tone resource unit.

7 . The method of claim 1 , the multiple resource units being for a transmission relating to a 6 GHz band.

8 . A system, comprising:

one or more processors; and

a memory comprising instructions that, when executed by the one or more processors, cause the system to perform operations comprising:

obtain notification of one or more ranges of frequencies corresponding to a 20 MHz resource unit to be avoided in a spectrum of available frequencies; and

allocate multiple resource units to a set of client devices that covers the available frequencies while excluding the one or more ranges of frequencies corresponding to the 20 MHz resource unit to be avoided, wherein when allocating the multiple resource units, the system is to:

select at least two resource units outside of the 20 MHz resource unit to be used for communicating data to a single client device; and

assign each remainder resource unit, outside of the at least two resource units and the 20 MHz resource unit, in either a multi-user multi-input multi-output (MU-MIMO) configuration, or a single-user multi-input multi-output (SU-MIMO) configuration.

9 . The system of claim 8 , wherein obtaining notification of the one or more ranges of frequencies is based on operations comprising to:

monitor the one or more ranges of frequencies for interference; and

detect the interference for the one or more ranges of frequencies as above a threshold level of interference,

wherein the one or more ranges of frequencies are designated as to be avoided based on the interference being above the threshold.

10 . The system of claim 8 , wherein the at least two resource units, the 20 MHz resource unit, and the remainder resource units comprise an orthogonal frequency-division multiple access (OFDMA) frame.

11 . The system of claim 8 , the operations further comprising to:

select at least two resource units outside of the 20 MHz resource unit to be avoided to be used for communicating data to a single client device in duplicate; and

assign each remainder resource unit, outside of the at least two resource units selected for transmitting the data in duplicate and the 20 MHz resource unit to be avoided, to other client devices in a single-user multi-input multi-output (SU-MIMO) configuration.

12 . The system of claim 8 , the multiple resource units being for a 160 MHz transmission.

13 . The system of claim 12 , the 160 MHz transmission including a multiple user (MU) transmission.

14 . The system of claim 12 , the 160 MHz transmission including a 996-tone resource unit.

15 . The system of claim 8 , the multiple resource units being for a 320 MHz transmission.

16 . The system of claim 15 , the 320 MHz transmission including a multiple user (MU) transmission.

17 . The system of claim 15 , the 320 MHz transmission including at least one 996-tone resource unit.

18 . The system of claim 8 , the multiple resource units being for a transmission relating to a 6 GHz band.
