1. A transmission device of a wireless local area network (WLAN) system, the transmission device comprising:
a transceiver configured to generate a physical layer convergence protocol (PLCP) protocol data unit (PPDU) including a preamble and a payload and to transmit the generated PPDU to at least one receiving device; and
a processor controlling the transceiver,
wherein the preamble comprises a plurality of training fields and a plurality of signaling fields, the plurality of signaling fields including a common field and a plurality of user-specific fields,
wherein resource unit (RU) allocation information for the at least one receiving device is included in the common field, and
wherein the RU allocation information comprises a first subfield indicating an arrangement of RUs and a number of subcarriers of each of the RUs in a frequency domain corresponding to the PPDU and a second subfield indicating a portion of the RUs to be combined to form a multiple RU among the RUs according to the arrangement and the number of subcarriers indicated by the first subfield.
