Abstract

Provided are a power control method and device, and a base station. The method comprises: when the service type of a user equipment is a pre-designated service type, acquiring an HARQ process activation / deactivation mark of the user equipment; and in a deactivated HARQ process corresponding to the HARQ process deactivation mark of the user equipment, adjusting at least one of the power control related parameters, so as to reduce the transmitting power of the user equipment. By implementing the embodiments of the present invention, when a certain HARQ process is deactivated, the base station can notify the user equipment to reduce the transmitting power, so as to reduce the uplink interference, thereby increasing the uplink capacity of a system, reducing unnecessary power waste and improving the standby time of the user equipment.
