Abstract:
1. A method for controlling uplink power of a Long Term Evolution (LTE) system, comprising: obtaining, by a mobile terminal, uplink transmit powers of carriers; sending, by the mobile terminal, first notification signaling to a base station if a difference between the obtained uplink transmit powers of different carriers exceeds a specific threshold, wherein the specific threshold is determined according to a power amplifier parameter applied to carrier aggregation and receiver performance of the mobile terminal; and sending, by the mobile terminal, second notification signaling to the base station if a sum of the obtained uplink transmit powers of carriers exceeds a preset threshold, wherein the preset threshold is determined according to maximum transmit power of the mobile terminal, maximum allowed power configured by the base station, and a resource management parameter planned by a network, wherein the specific threshold comprises: M the preset threshold comprises: M
