| 摘要 |
The present invention discloses a preamble Preamble sending method, including: acquiring a first uplink transmission gap, where the first uplink transmission gap is a time interval between initiation, by a terminal, of current uplink transmission and termination of the most recent uplink transmission; and when the first uplink transmission gap is greater than or equal to at least one time threshold in a first preset time threshold, sending a Preamble that includes a DPCCH to a network side. In the preamble Preamble sending method disclosed in the present invention, when a terminal initiates uplink transmission, the terminal first acquires a time interval between initiation, by the terminal, of current uplink transmission and termination of the most recent uplink transmission; and when the time interval is greater than or equal to at least one time threshold in a preset time threshold, the terminal sends a Preamble that includes a DPCCH to a network side, so that a network-side device located at a base station can control uplink transmission power of the terminal according to a sent DPCCH pulse. |
