The invention discloses a signal configuration method, an information processing method, and devices. The signal configuration method comprises the following steps: selecting a plurality of synchronous windows contained in a preset period of time to carry a synchronous signal; configuring a broadcast channel according to the preset constraint relationship between the synchronous signal and the broadcast channel; and sending a configured signal by means of periodic trigger or non-periodic trigger, wherein the configured signal includes at least one of the synchronous signal and the broadcast channel, and a complete process of signal transmission is completed in the preset period of time. Each synchronous window includes a plurality of successive symbols. The synchronous signal is carried by a plurality of subcarriers of each symbol. The transmission process of the synchronous signal is completed in the preset period of time.

The invention discloses a method for adjusting the frequency deviation of a mobile terminal and a device thereof. The method comprises the following steps: a terminal detects the intensity of downlink broadcast signals of a service cell and neighbor cells; the terminal judges whether the intensity difference of the downlink broadcast signals between the service cell and the strongest neighbor cell is larger than the threshold; if yes, the terminal calculates the downlink frequency deviation according to the broadcast channel of the service cell and adopts the frequency deviation as the frequency deviation estimated value of the mobile terminal; if not, the terminal calculates the downlink frequency deviation of the service cell according to the broadcast channel of the service cell and the downlink frequency deviation of the strongest neighbor cell according to the broadcast channel of the strongest neighbor cell, combines the two frequency deviations as the frequency deviation estimated value of the mobile terminal, and corrects the local carrier frequency of the terminal through the smooth frequency deviation estimated value of the terminal. By using the invention, the problem of abrupt change of the frequency deviation when the terminal transits from the service cell to a neighbor cell can be avoided, the performance of the terminal in a high mobility environment can be improved, and the invention is also suitable for a low mobility terminal.
