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 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.

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 of processing a data frame in a wireless communication system using multi-user multiple input multiple output. The method comprises: receiving, by a receiver, group control information to assign one or more groups from an access point, the group control information indicating a group sequence number (502), bitmap information (503) and stream information (504); and receiving, by the receiver, a data frame from the access point after receiving the group control information, the data frame including the group sequence number and the stream information, wherein the bitmap information (503) is used to inform whether the data frame is received from a corresponding group when the receive belongs to a plurality of groups that are expressed using the group sequence number, and wherein the stream information (504) indicates a stream location to be received by the receiver in a MU-MIMO environment and indicates a position for at least one stream of a plurality of streams that are classified into a plurality of groups.
