摘要

Disclosed are a method and a device for allocating resource units using leftover tones in a wireless LAN. The method for allocating resource units using leftover tones in a wireless LAN may comprise the steps of: an AP generating PPDUs to be transmitted to a plurality of STAs; and the AP transmitting the PPDUs to the plurality of STAs on all frequency bands, wherein the PPDUs are transmitted from each of a plurality of resource unit sets respectively allocated to each of the plurality of STAs, wherein each of the plurality of resource unit sets includes a first resource unit set and a second resource unit set, wherein the first resource unit set includes at least one resource unit, the second resource unit set includes one tone design resource unit, and wherein the tone design resource unit may include at least one other resource unit and at least one additional tone unit.

說明書

According to the exemplary embodiment of the present invention, the number of additional tone units being added to the tone design resource unit may vary in accordance with the number of 26-tone resource units configuring the tone design resource unit. For example, the number of additional tone units that are to be linearly added to the tone design resource unit may be linearly increased in accordance with the number of 26-tone resource units configuring the tone design resource unit.

Referring to FIG. 2, the number of 4-tone additional tone units being added for the configuration of the tone design resource unit may vary in accordance with the number of 26-tone resource units configuring the tone design resource unit.

More specifically, in case the number of 26-tone resource units configuring the tone design resource unit is equal to 1, one (1) 4-tone additional tone unit may be used so as to define a 30-tone design resource unit 200. 26-tone resource units and/or 242-tone resource units may be allocated within remaining frequency resources that remain after excluding the frequency resources that are allocated to the 30-tone tone design resource unit 200.

In case the number of 26-tone resource units configuring the tone design resource unit is equal to 2, two (2) 4-tone additional tone units may be used so as to define a 60-tone design resource unit (2×26 tones+2×4 tones=60 tones) 210. 26-tone resource units and/or 242-tone resource units may be allocated within remaining frequency resources that remain after excluding the frequency resources that are allocated to the 60-tone tone design resource unit 210.
