Embodiment Construction

[0023] In the prior art solution, the APT uses few points for adjusting the working voltage of the power amplifier, and the voltage value supplied to the power amplifier often exceeds the minimum voltage value for normal operation of the power amplifier, thus resulting in large power consumption.

[0024] The embodiment of the present invention selects the mapping relationship between the configured power segment and the driving voltage from the stored APT information through the obtained transmission power of the power amplifier, and obtains the corresponding driving voltage to drive the power amplifier. Each power segment corresponds to The driving voltage values ​​are all equal to the minimum driving voltage value corresponding to the maximum power in the power segment, which can effectively reduce the power consumption of the power amplifier.

[0025] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodimen...

Abstract

The invention discloses a user terminal and a method and a device for lowering the power consumption of the user terminal. The method for lowering the power consumption of the user terminal comprises the following steps: acquiring the transmitting power of a power amplifier in the current working state of the user terminal; selecting a mapping relation between configured power segments and driving voltages from stored automatic power-consumption-saving technical information, and acquiring a driving voltage corresponding to the transmitting power of the power amplifier, wherein a voltage value corresponding to each power segment is equal to a minimum driving voltage value corresponding to the maximum power in the power segment; and driving the power amplifier by adopting the acquired driving voltage. Through adoption of the method and the device, the power consumption of the power amplifier can be effectively lowered.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a user terminal and a method and device for reducing power consumption thereof. Background technique [0002] Long Term Evolution (LTE) technology is the long-term evolution of the general mobile communication system technology led by the 3rd Generation Partnership Project (3GPP), and is currently a widely recognized wireless communication technology. [0003] When an LTE terminal is performing data transmission, such as a voice call or a data call, due to the large dynamic range of the LTE signal power, the power amplifier (Power Amplifier, PA) of the LTE terminal consumes a large amount of power, resulting in the operation of the LTE terminal. Time shortened. Auto Power Saving Technology (APT) can effectively improve the power consumption of LTE terminals during voice or data calls. [0004] In the prior art solution, when using the APT, the transmit powe...
