1. A method for allocating resource units in a wireless local area network (LAN), the method comprising:

  • generating, by an access point (AP), a PHY layer protocol data unit (PPDU) that is to be transmitted to a plurality of stations (STAs); and

    transmitting, by the AP, the PPDU to the plurality of STAs through an entire frequency bandwidth including at least one container,wherein the PPDU includes resource allocation information,wherein the resource allocation information indicates 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 corresponding to the first resource unit is greater than a number of tones corresponding to the plurality of second resource units, andwherein when 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 applied in the first resource unit, the resource allocation information further indicates a number of STAs to which the MU MIMO is applied.
