摘要： The present invention provides a method and a system for transmitting data that carries indication information, and an apparatus. The method includes: generating, by a transmit end node, an indication frame; and sending, by the transmit end node, the indication frame to a receive end node, where the indication frame includes available-channel indication information or idle bandwidth information. The receive end node can directly receive indication frames sent by multiple transmit end nodes, and does not need to receive, one piece by one piece, indication information sent by the multiple transmit end nodes. This greatly reduces transmission overheads.

摘要： The present invention discloses a transmission device and a method for transmitting a data frame, which relate to the communications field, reduce signaling overheads, and reduce a delay in reception of a data field. A specific solution is: an acquiring unit acquires LTF parameters, and acquires a start position I of allocated subcarriers, where the LTF parameters include a frequency domain transform parameter and a time domain transform parameter that are required for generating an LTF sequence; a frequency domain transform unit performs, according to the frequency domain transform parameter and the start position I, a frequency domain transform on an LTF basic sequence to obtain an LTF symbol; a time domain transform unit performs, according to the time domain transform parameter, a time domain transform on the LTF symbol to obtain the LTF sequence; and a sending unit adds the LTF sequence to a first data frame, and sends the first data frame to a second device, so that the second device determines the LTF basic sequence according to the LTF sequence and performs channel estimation according to the LTF basic sequence. The present invention is used in a transmission process of a data frame.
