1. 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 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;
receive, via the communication channel and from the at least one other device, an uplink (UL) orthogonal frequency division multiple access (OFDMA) frame including the data and a second value by which the bandwidth is reduced, the OFDMA frame transmitted in a second bandwidth of the RU less than or equal to a first bandwidth according to the value; and
process the UL OFDMA frame including the data.
