<p>The present invention provides an uplink transmission method, an uplink transmission device, and a terminal. The method comprises: receiving an uplink timing synchronization shift command; determining a current timing advance in accordance with the uplink timing synchronization shift command; judging whether the current timing advance meets a prediction condition where the uplink signal is to enter into a demodulation window, so as to obtain a first judgment result; transmitting the uplink signal in accordance with the current timing advance when the first judgment result is yes; and updating the current timing advance when the first judgment result is no so that the updated current timing advance meets the prediction condition where the uplink signal is to enter into a demodulation window, and transmitting the uplink signal in accordance with the updated current timing advance. The present invention provides a prediction and prevention way when an uplink signal goes beyond the range of a base station demodulation window, thereby to reduce the possibility of the uplink signal going beyond the base station demodulation window and enhance reliability of the uplink.</p> |
