The present invention discloses a power adjustment method and a device, and belongs to the field of communications. The method is applied to a terminal comprising a baseband transmitting unit. The method comprises the steps of acquiring the target transmitting power transmitted by a base station; acquiring the power attenuation value of a signal transmitted by the baseband transmitting unit and forwarded to an air interface; summing up the target transmitting power and the attenuation value, and obtaining a current transmitting power; according to the current transmitting power, transmitting the signal by the baseband transmitting unit. According to the technical scheme of the invention, the power of the attenuated signal is equal to the target transmitting power, so that the strength of the signal received by the base station is increased. Meanwhile, the power adjustment process can be completed without the need of interacting with the base station. Therefore, the problem in the prior art that the power adjustment is slow in process and low in efficiency due to multiple interaction processes between the base station and the terminal can be solved. As a result, the power adjustment efficiency is improved.
Description
technical field [0001] The present invention relates to the communication field, in particular to a power adjustment method and device. Background technique [0002] When the baseband transmitting unit in the terminal transmits a signal to the base station, it needs to transmit the signal at the target transmit power sent by the base station. Since the power of the signal will be attenuated during the process of forwarding to the air interface, the power of the signal when it reaches the air interface is already lower than the target transmission power, resulting in a weak signal received by the base station. Therefore, the base station needs to adjust the baseband transmission unit according to the attenuation target transmit power. Wherein, the air interface is an air interface between the base station and the terminal. [0003] A power adjustment method provided by related technologies includes: the base station sends a first target transmission power to the terminal; t...
