Abstract: The present invention relates to a method for protecting MU-MIMO (Multi User-Multiple Input Multiple Output) data through a multi-RTS/CTS frame exchange in a MU-MIMO based wireless communication system. The method of the present invention comprises: a process where an indicator for VHT data protection is added to an RTS frame, using the structure of an RTS/CTS frame for an existing legacy terminal during the multi RTS/CTS frame exchange; a process where an access point designates and then transmits the duration period of the RTS frame while transmitting the RTS frame; and a process where wireless terminals up to the (n-1)th terminal designate the duration period of the CTS frame as '0' and send the designated duration period, while only the n-th wireless terminal designates NAV for data protection.

Abstract: The present invention relates to a method for recovering a frame that failed to be transmitted to a plurality of wireless terminals by using a group number in a MU-MIMO (Multi-User Multiple Input Multiple Output) based wireless communication system. Following the transmission of a frame that requests for a response including group control information to the plurality of wireless terminals, if a response frame is not normally received from a particular wireless terminal, a request frame is transmitted to the wireless terminal that has failed to receive the response frame as a destination, after a period of time for receiving the response frame from each of the plurality of wireless terminals that consists of a group. In another embodiment of the present invention, if the response frame is not normally received from a particular wireless terminal, a request frame is transmitted to wireless terminals starting from the wireless terminal that has failed to receive the response frame down to the last wireless terminal, in accordance with the transmission order of the response frame.
