The invention discloses an unauthorized frequency band uplink power control method and related equipment, used for providing an uplink power control scheme applicable to an unauthorized frequency band LTE system. The method comprises the steps as follows: a base station acquires interference strength information of interference communication nodes of the base station and/or interference communication nodes around a terminal; the base station determines uplink transmission efficiency of the terminal according to the interference strength information; and the base station configures the terminal to transmit an uplink signal at an unauthorized frequency band according to the uplink transmission power.
