    • Provided a method for simultaneously transmitting data frames to a plurality of STAs in a multi-user based wireless communication system. The method includes: requesting sounding or feedback for the plurality of STAs by using a first control information frame containing first group information; receiving responses to the sounding or feedback request; reconfiguring the plurality of STAs composing the first group into a plurality of second groups on the basis of the responses such that the sum of maximum transport streams of the respective STAs composing one group becomes equal to or less than the maximum number of streams transmitted by an AP; transmitting a second control information frame containing second group information on the respective second groups to the plurality of STAs composing the first group; and transmitting data frames by using the second group information.
    • 提供了一种用于在基于多用户的无线通信系统中同时向多个STA发送数据帧的方法。 该方法包括:通过使用包含第一组信息的第一控制信息帧来请求对多个STA的探测或反馈; 接收响应声音或反馈请求; 基于所述响应,将构成第一组的多个STA重新配置成多个第二组,使得构成一组的各个STA的最大传输流之和变得等于或小于由一 AP; 将包含关于各个第二组的第二组信息的第二控制信息帧发送到构成第一组的多个STA; 以及通过使用第二组信息发送数据帧。

    • A method for simultaneously transmitting packets having different lengths to two or more users in a wireless communication system includes: generating the packets which are to be transmitted to the respective users; and simultaneously transmitting the generated packets to the respective users. Each of the packets contains information on the position of a symbol to which a tail field of the packet belongs, and the information on the position of the symbol to which the tail field belongs includes at least one of the maximum symbol number of the packet, the symbol number of transmission data of the packet, positional information of a last aggregated MAC protocol data unit (A-MPDU) subframe, and positional information of a null delimiter.
    • 一种用于在无线通信系统中同时向两个或多个用户发送具有不同长度的分组的方法包括:生成要发送给各个用户的分组; 同时将生成的分组发送给各个用户。 每个分组包含关于分组的尾部字段所属的符号的位置的信息,并且关于尾部字段所属的符号的位置的信息包括分组的最大符号号中的至少一个, 分组的发送数据的符号数,最后聚合的MAC协议数据单元(A-MPDU)子帧的位置信息和空分隔符的位置信息。
