1. A method of receiving a physical layer convergence procedure (PLCP) protocol data unit (PPDU) by an access point (AP) in a wireless local area (LAN) system, the method comprising:

  • allocating a first transmission channel bandwidth to a first station (STA) which is multiple input multiple output (MIMO)-paired with the AP;

    allocating a second transmission channel bandwidth to a second STA which is MIMO-paired with the AP;

    transmitting to the first STA and the second STA a sync trigger for determining a time point at which the first STA transmits a first PPDU and a time point at which the second STA transmits a second PPDU; and

    receiving simultaneously the first PPDU and the second PPDU from the first STA and the second STA.
