    Abstract: A method of communicating, by a first device, with at least one second device in a wireless local area network (WLAN) system includes allocating at least one resource unit (RU) within a bandwidth to a second device; generating at least one subfield defining the at least one RU; generating a trigger frame comprising a user information field comprising the at least one subfield, and transmitting a PPDU including the trigger frame to the at least one second device, wherein the generating comprises setting at least seven bits associated with the at least one RU and setting at least two bits as a value defining a subband that includes the at least one RU when the band width comprises at least four subbands.

    Abstract: A method for a first device to communicate with at least one second device in a wireless local area network (WLAN) system includes providing a first trigger frame to at least one second device, the first trigger frame requesting at least one sounding null data packet (NDP), providing a feedback frame to the at least one second device, the feedback frame including feedback information generated based on the at least one sounding NDP, and providing a second trigger frame to the at least one second device, the second trigger frame requesting at least one beamformed physical layer protocol data unit (PPDU), each of the first trigger frame and the feedback frame including a sounding dialog token number field having a sounding sequence number.

    Abstract: An apparatus and a method for allocating a multiple resource unit (RU) for a user in a wireless local area network (WLAN) system are provided. A transmission device of the WLAN system includes a transceiver that generates a physical layer convergence protocol (PLCP) protocol data unit (PPDU) including a preamble and a payload and transmitting the generated PPDU to at least one receiving device and a processor controlling the transceiver. The preamble includes a plurality of training fields and a plurality of signaling fields. Resource unit (RU) allocation information on the at least one receiving device is included in one of the plurality of signaling fields. The RU allocation information includes a first subfield indicating an arrangement of 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.
