Claim of US Patent No. 10,251,177

1. A method for allocating wireless resources in a wireless local area network (WLAN), comprising:receiving, by a station (STA), a physical protocol data unit (PPDU) from an access point (AP),
wherein the PPDU is received based on a resource unit addressed to the STA among a plurality of resource units corresponding to the entire bandwidth of the PPDU,
wherein the plurality of resource units are allocated based on orthogonal frequency division multiple access (OFDMA),
wherein the plurality of resource units comprise 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 adjacent to direct current (DC) tones of the entire bandwidth, the two STUs are defined as a logical resource unit.
