一種傳輸設備和數據幀的傳輸方法技術

本發明專利技術公開了一種傳輸設備和數據幀的傳輸方法，涉及通信領域，節省了信令開銷，降低了數據部分接收的時延。具體方案為：獲取單元獲取LTF參數，并獲取分配的子載波起始位置I；其中，LTF參數包括：生成LTF序列所需的頻域變換參數以及時域變換參數；頻域變換單元根據頻域變換參數和起始位置I，對LTF基本序列進行頻域變換得到LTF符號；時域變換單元根據時域變換參數，對LTF符號進行時域變換得到LTF序列；發送單元將LTF序列攜帶在第一數據幀中發送至第二設備，以便第二設備根據LTF序列確定LTF基本序列，并根據LTF基本序列進行信道估計。本發明專利技術用于數據幀的傳輸過程中。

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.
