Method and device for allocating resource unit on basis of container in wireless LAN
First Claim
1. A method in a wireless local area network (WLAN), the method comprising:
- receiving, by a station (STA) among a plurality of STAs, a physical (PHY) layer protocol data unit (PPDU) that is transmitted to the plurality of STAs, wherein the PPDU is transmitted through an entire frequency bandwidth including at least one container; and
decoding, by the STA, the PPDU for the at least one container,wherein the PPDU includes resource allocation information,wherein the resource allocation information includes first information on a number of STAs being allocated to each of the at least one container,wherein each of the at least one container includes one first resource unit or a plurality of second resource units,wherein a number of tones related to the first resource unit is greater than a number of tones related to the plurality of second resource units,wherein a specific container of the at least one container includes only the first resource unit and multiple user multiple input multiple output (MU MIMO) is performed for the first resource unit, andwherein the resource allocation information further includes second information on a number of STAs performing the MU MIMO.

Abstract
Disclosed are a method and a device for allocating a resource unit on the basis of a container in a wireless LAN. The method for allocating a resource unit in a wireless LAN comprises the steps of: generating, by an AP, a PPDU to be transmitted to a plurality of STAs; and transmitting, by the AP, the PPDU to the plurality of STAs through at least one container allocated on the entire frequency band, wherein the PPDU includes MU/SU transmission indication information and resource allocation information for each container, the MU/SU transmission indication information includes information on whether an SU-based transmission or an MU-based transmission is carried out on the entire bandwidth, and the resource allocation information for each container can include information on the number of STAs allocated to each of the at least one container.
