Abstract: A baseband circuit in a transmitting device of a WLAN may include at least one processor configured to generate a PPDU comprising a preamble and a payload. The preamble includes training fields and signaling fields, and the payload includes a data field. A first one of the signaling fields includes a compression mode field indicating whether resource unit (RU) allocation information designated for at least one receiving device is included in a second one of the signaling fields. A binary value of the compression mode field represents whether the RU allocation information is included and size information associated with the RU allocated to the at least one receiving device.
