Abstract
A method for controlling uplink power of an LTE system, a base station, and a mobile terminal are disclosed according to the embodiments of the present invention. The method includes: obtaining uplink transmit power of each carrier; sending first notification signaling to a base station if a difference between the obtained uplink transmit power of each carrier exceeds a specific threshold; and sending second notification signaling to the base station if a sum of the obtained uplink transmit power of each carrier exceeds a preset threshold. Thresholds are determined according to network conditions, and uplink power of a carrier is adjusted in a balanced way, a bit error rate is reduced and a case that a low-performance carrier is forced to be interrupted is prevented.
