Resource unit allocation for orthogonal-frequency-division multiple access communications

A method of controlling a wireless access point, comprising:

• causing the wireless access point to identify any groupings of subcarriers of a wireless channel in which
• all of the non-protocol Fast Fourier Transform (FFT) bins in the grouping have respective signal strength values exceeding a first threshold, wherein non-protocol FFT bins correspond to bins that contain signals not used in protocols supported by the wireless access point;
• and
• a bandwidth of the grouping does not exceed a second threshold;
• causing the wireless access point to identify any resource units of the wireless channel that overlap with any of the identified groupings, wherein resource units comprise non-overlapping groups of subcarriers of the wireless channel;
• and
• causing the wireless access point to, in allocating the resource units to client devices for an orthogonal frequency division multiple access (OFDMA) communication, skip the identified resource units.

A non-transitory machine readable medium comprising instructions that are to, when executed by processing circuitry that controls a wireless access point, cause the processing circuitry to:

• identify any groupings of subcarriers of a wireless channel of the wireless access point in which
• all of the non-protocol Fast Fourier Transform (FFT) bins in the grouping have respective signal strength values exceeding a first threshold, wherein non-protocol FFT bins correspond to bins that contain signals not used in protocols supported by the wireless access point;
• and
• a bandwidth of the grouping does not exceed a second threshold;
• identify any resource units of the wireless channel that overlap with any of the identified groupings, wherein resource units comprise non-overlapping groups of subcarriers of the wireless channel;
• and
• cause the wireless access point to, in allocating the resource units to client devices for an orthogonal frequency division multiple access (OFDMA) communication, skip the identified resource units.
