1. A method for allocating wireless resources in a wireless local area network (WLAN), the method comprising:receiving, by a station (STA), a physical protocol data unit (PPDU) including a signal field and a data field from an access point (AP) based on an entire bandwidth,
wherein a plurality of resource units (RUs) are allocated for the entire bandwidth based on orthogonal frequency division multiple access (OFDMA),
wherein the plurality of RUs includes a basic tone unit (BTU) and a small tone unit (STU) having a number of tones being less than that of the BTU, and
wherein when two STUs are allocated contiguously to direct current (DC) tones of the entire bandwidth, the two STUs are defined as a logical RU; and
decoding, by the STA, the signal field to determine an RU for the STA,
wherein the data field is decoded based on the two STUs when the RU is the logical RU.
