Signaling and decoding of punctured subbands in trigger-based ppdu

A device, comprising:

• a communication interface;
• and
• processing circuitry that is coupled to the communication interface, wherein at least one of the communication interface or the processing circuitry is configured to:
• generate, in response to a trigger frame from a second device allocating a resource unit (RU) having a first bandwidth, an uplink (UL) orthogonal frequency division multiple access (OFDMA) frame including data, the trigger frame comprising a field having a value indicating a resolution with which at least one other device is allowed to reduce a bandwidth of the allocated RU for transmitting the data via a communication channel;
• and
• transmit, based on the value indicating the resolution with which at least one other device is allowed to reduce the bandwidth of the allocated RU for transmitting the data via the communication channel, the UL OFDMA frame in a second bandwidth of the RU,
• wherein the second bandwidth is less than the first bandwidth by the value.

A circuitry comprising:

• a communication interface;
• and
• a processor that is coupled to the communication interface, wherein at least one of the communication interface or the processing circuitry is configured to:
• generate a trigger frame comprising a field having a value indicating a resolution with which at least one other device is allowed to reduce a bandwidth of an allocated resource unit (RU) for transmitting data via a communication channel;
• and
• transmit, via the communication channel, the trigger frame to the at least one other device,
• wherein the at least one other device is configured to transmit a second frame according to the value in the field indicating the resolution with which the at least one other device is allowed to reduce the bandwidth.
