An uplink synchronization method and a terminal. The implementation of the terminal is as follows: if the terminal is a support terminal, the terminal comprises: an information obtaining unit (504), used for obtaining an access identification of a beneficial terminal and obtaining an uplink port number used by the support terminal for sending a reference signal; a reference signal sending unit (501), used for sending the reference signal on an uplink port to an access device by using the access identification of the beneficial device; an adjustment value reception unit (502), used for receiving an adjustment value of uplink synchronization information from the access device; and a synchronization unit (503), used for performing uplink synchronization according to the adjustment value received by the adjustment value reception unit, of the uplink synchronization information. The support terminal sends a reference signal by using an access identification of the beneficial terminal, and receives an adjustment value of synchronization information of the support terminal, thereby implementing uplink synchronization. The support terminal does not need to access a network, thereby avoiding interference of the support terminal to another terminal and the beneficial terminal on an access device side, and saving a preamble signal resource. |
