Title
(EN) Communication method and device for terminal and base station
(ZH) 一种终端与基站的通信方法和装置
Abstract
(EN)
The embodiment of the invention provides a communication method and device for a terminal and a base station, and the communication method for the terminal and the base station comprises: the terminalsending a first data frame to relay equipment in a first mode, the first data frame comprising a first lead code and a first message set, and the first lead code being used for waking up the relay equipment; and the terminal sending a second data frame to the relay device in the first mode, wherein the second data frame comprises a second preamble and a second information set, the second data frame is sent by the terminal after the first data frame is sent and a first time interval is passed, and the length of the second preamble is smaller than that of the first preamble; and the terminal receiving a third data frame sent by the relay device in the first mode, and sending the third data frame is sent to the terminal after the relay device receives the third data frame from the base station. The embodiment of the invention can effectively expand the coverage area of the network.
