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(shuō)明書

In case the number of 26-tone resource units configuring the tone design resource unit is equal to 2, 1 4-tone additional tone unit may be used so as to define a 56-tone tone design resource unit (2×26 tones+1×4 tones=56 tones) 510. The 8 leftover tones within the bandwidth may be defined as 2 4-tone additional tone units (first 4-tone additional tone unit and second 4-tone additional tone unit). A first 4-tone additional tone unit may configure a first 56-tone tone design resource unit along with two 26-tone resource units, and a second 4-tone additional tone unit may configure a second 56-tone tone design resource unit along with another two 26-tone resource units. 26-tone resource units and/or 242-tone resource units may be allocated within the remaining frequency resources.

In case the number of 26-tone resource units configuring the tone design resource unit is equal to 3, 1 4-tone additional tone unit may be used so as to define an 82-tone tone design resource unit (3×26 tones+1×4 tones=82 tones) 520. The 8 leftover tones within the bandwidth may be defined as 2 4-tone additional tone units (first 4-tone additional tone unit and second 4-tone additional tone unit). A first 4-tone additional tone unit may configure a first 82-tone tone design resource unit along with three 26-tone resource units, and a second 4-tone additional tone unit may configure a second 82-tone tone design resource unit along with another three 26-tone resource units. 26-tone resource units and/or 242-tone resource units may be allocated within the remaining frequency resources.
