摘要： 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.

摘要： The present invention relates to methods for transmitting a frame by grouping a plurality of wireless terminals in a multiuser based wireless communication system. The present invention includes a method for transmitting a frame by including information about multiple receiver terminals in a MAC frame, another method for transmitting a frame by allocating group addresses and then using a corresponding group address for frame transmission, and yet another method for transmitting a frame by using a unique group sequence number that is allocated to each group and group control information that contains bitmap information. The group control information is included in a destination address field of a MAC layer, or in a signal field of a physical layer, or in both the MAC layer and the physical layer.

摘要： The present invention relates to a method for efficient transmission of a request frame such as an RTS/CTS frame and a response frame in response to the request frame in a multi-user based wireless communication system. The method of the present invention comprises: a process where wireless terminals transmit a response frame at their own response frame transmission time through a request frame that contains information about a plurality of wireless terminals and information about the response frame transmission time of the respective wireless terminals; a process where the respective wireless terminals transmit a response frame according to a token scheme such that the response frame is transmitted to a final access point; and a process where only a representative wireless terminal selected depending on a given wireless environment receives the response frame.

摘要： The present invention relates to a method and apparatus for transceiving data. A method in which a transmitting terminal transmits data to a receiving terminal in a MIMO system according to one embodiment of the present invention comprises the following steps: generating a data field containing the data; generating a signal field containing information on the data field; generating a data frame containing the data field and the signal field; and transmitting the data frame to the receiving terminal. According to the present invention, an end of the frame being transmitted is accurately notified to the receiving terminal in a communication system in which the frame is transmitted using MIMO, thereby decoding the frame in a more efficient manner at the receiving terminal.
