Abstract:
The present invention relates to the field of communications. Provided in embodiments of the present invention are a random access method and a terminal capable of adjusting timing advance (TA) of a terminal and increasing coverage of a base station under conditions of high frequency and large subcarrier intervals. The method comprises: a terminal receiving a first uplink timing advance (TA) transmitted by a base station, and transmitting first uplink data to the base station according to the first TA; the terminal receiving a reception failure response transmitted by the base station, and updating the first TA to a second TA, the second TA being greater than the first TA, the reception failure response being used to indicate that the base station fails to receive the first uplink data; and the terminal transmitting second uplink data to the base station according to the second TA.
