UPLINK MU-MIMO UPLINK MU-MIMO METHOD OF TRANSMITTING REQUEST OF UPLINK MU-MIMO FOR UPLINK MU-MIMO COMMUNICATION

摘要

A frame transmission/reception method for multi-user-multi-input multi-out (MU-MIMO) communication in an access point (AP) is disclosed. The frame transmission/reception method according to an embodiment includes the steps of transmitting an uplink multi-user request (UL MU Request) frame requesting data frame transmission to a plurality of stations, and the same reception strength for the same period from the plurality of stations. Receiving a data frame, wherein the uplink multi-user request frame may include at least one of a transmission period of the data frame and reception intensity information at the access point of the data frame.
