一种传输设备和数据帧的传输方法技术

本发明专利技术公开了一种传输设备和数据帧的传输方法，涉及通信领域，节省了信令开销，降低了数据部分接收的时延。具体方案为：获取单元获取LTF参数，并获取分配的子载波起始位置I；其中，LTF参数包括：生成LTF序列所需的频域变换参数以及时域变换参数；频域变换单元根据频域变换参数和起始位置I，对LTF基本序列进行频域变换得到LTF符号；时域变换单元根据时域变换参数，对LTF符号进行时域变换得到LTF序列；发送单元将LTF序列携带在第一数据帧中发送至第二设备，以便第二设备根据LTF序列确定LTF基本序列，并根据LTF基本序列进行信道估计。本发明专利技术用于数据帧的传输过程中。

Transmission device and data frame transmission method

The invention discloses a transmission device and a method for transmitting a data frame, which relates to the communication field. The specific scheme is that the acquisition unit acquires LTF parameters, and obtain subcarrier starting position distribution of I; the LTF parameters include: LTF sequence generation required frequency transformation parameters and time domain parameters; frequency conversion unit according to the frequency domain transform parameters and the initial position of the I, the LTF sequence in frequency domain transform LTF time domain symbols; transform unit according to the time domain parameters of LTF symbols are the time domain LTF sequence; the sending unit to carrying a LTF sequence in the first data frame is transmitted to the second device, so that the second equipment according to the sequence of LTF LTF to determine the basic sequence and channel estimation based on LTF sequence. The invention is used in the transmission process of data frames.
