WIPO Patent Application WO/2019/237963
Kind Code:
A1
Abstract:
Embodiments of the present application provide a server data sending method and apparatus. The method comprises: a server obtains crystal oscillator error information and operating rate information of a terminal; the server configures preamble length information according to the crystal oscillator error information and the operating rate information; the server sends a downlink data frame to the terminal, the downlink data frame comprising a preamble having the preamble length information. In the embodiments of the present application, in the case that a crystal oscillator error in the terminal cannot be changed, the terminal can detect the preamble in a longer time period by adjusting the length of the preamble, and a success rate of sending the downlink data frame is improved.
