PPDU RECEIVING METHOD AND APPARATUS BASED ON THE MIMO TECHNIQUE IN A WLAN SYSTEM

摘要

Provided is a method for receiving a PLCP (physical layer convergence procedure) protocol data unit (PPDU) by an access point (AP) in a WLAN system. The method comprises: allocating a first transmission channel bandwidth to a first STA having MIMO (Multiple Input Multiple Output) pairing with the AP; allocating a second transmission channel bandwidth to a second STA having MIMO pairing with the AP; transmitting to the first STA and the second STA a sync trigger for determining the transmission starting point of a first PPDU to be done by the first STA and the transmission starting point of a second PPDU to be done by the second STA; and receiving the first PPDU and the second PPDU from the first STA and the second STA simultaneously.
