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 transmitting, to each of a plurality of stations (STAs), an uplink multi-user request (UL MU request) frame requesting transmission of a data frame, and receiving, from each of the plurality of STAs, the data frame during an identical period of time based on an identical reception intensity, wherein the UL MU request frame includes at least one of information on a transmission time of the data frame and information on a reception intensity of the data frame in the AP.
