Method and device for transmitting data for plurality of stations through plurality of bands in wireless LAN system
First Claim
1. A method for transmitting a signal in a wireless LAN, comprising:
- allocating, by an access point (AR) including in a first basic service set (BSS), a first frequency band and a second frequency band,wherein a non-contiguous band exits between the first and second frequency band,wherein the non-contiguous band is overlapped with a hearable interfering source that canbe received from a second BSS, andwherein the second BSS is an overlapping basic service set (QBSS) for the first BSS; and
transmitting, by the AR, a first signal to a first station through the first frequency band and a second signal to a second station through the second frequency band,wherein a first leftover tone is inserted in a resource unit (RU) closest to the non contiguous band in the first frequency band,wherein a second leftover tone is inserted in a RU closest to the non-contiguous band inthe second frequency band,wherein the first and second leftover tones have 8 tones respectively,wherein a first frequency resource through which the first signal is transmitted in the first frequency band has 234 tones, andwherein a second frequency resource through which the second signal is transmitted in the second frequency band has 234 tones.

Abstract
Proposed are a method and a device for transmitting a signal including a data field in a wireless LAN. For example, an access point (AP) allocates, to a second station, a second frequency band adjacent to a first frequency band, wherein the second frequency band can include a plurality of resource units. In addition, a signal including the data field can be transmitted to the second station through the allocated second frequency band. Furthermore, when the first frequency band is allocated to the first station, the AP can allocate, to the second station, as a null resource unit, a resource unit adjacent to the first frequency band among the plurality of resource units.
