In Table 6, a case when 9 26-tone resource units are allocated within the 20 MHz bandwidth will be assumed.
Referring to Table 6, one STA may be allocated with a first resource unit group including 1 26-tone resource unit, a second resource unit group including a first tone design resource unit 1200, which is configured of 2 26-tone resource units and 1 4-tone additional tone unit, a third resource unit group including a second tone design resource unit 1250, which is configured of 3 26-tone resource units and 1 4-tone additional tone unit, and a fourth resource unit group including 4 26-tone resource units.
In case the first tone design resource unit 1200 and the second tone design resource unit 1250 are being supported, 12 different types of allocation cases may be supported for the 20 MHz bandwidth.
Although gain of the subband selective transmission of the second tone design resource unit 1250 may be deduced due to the allocation of the first tone design resource unit 1200, the allocation of the first tone design resource unit 1200 and the second tone design resource unit 1250 may be determined through the scheduling of the AP.
