Abstract:
Provided is a method of transmitting and receiving a frame for a multi-user multiple-input and multiple-output (MU-MIMO) communication in an access point (AP), the method including determining at least one transmission station (STA), transmitting, to the transmission STA, an uplink multi-user poll (UL MU poll) frame requesting a data frame, receiving the data frame from the at least one transmission STA simultaneously, and transmitting an acknowledgement (ACK) frame to the at least one transmission STA in response to the receiving.
