Radio frequency receiving circuit power saving method and terminal

Abstract

The invention discloses a radio frequency receiving circuit power saving method. The method comprises steps: radio frequency signals are received; whether the total air interface signal power of a receiving antenna of the radio frequency receiving circuit is larger than a first threshold value and whether the transmitting power of a transmitting antenna of the radio frequency receiving circuit is smaller than a second threshold value are judged; if yes, whether conversion out-of-band interference power is larger than a third threshold value is judged; if not, whether the performance of the radio frequency receiving circuit is larger than or equal to a fourth threshold value is judged; if yes, the times when the performance of the radio frequency receiving circuit is larger than or equal to the fourth threshold value in a first preset time are counted whether to meet a fifth threshold value; and if yes, the radio frequency receiving circuit is controlled to enter a power saving working state mode. The invention also discloses a terminal. Through the above mode, the performance loss of the radio frequency receiving circuit can be controlled in an allowable range, and the optimal tradeoff between the standby time of the terminal and the service performance is achieved.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a power saving method and a terminal for a radio frequency receiving circuit. Background technique [0002] In order to allow the battery power of the terminal to be used for a longer period of time, the terminal needs to frequently switch between the normal working mode (High Power Mode, HPM) and the power saving working mode (Low Power Mode, LPM) to reduce the power consumption of the terminal. to increase battery life. The standby time and service performance have always been two Quality of Service (Quality of Service) that the terminal needs to weigh. When the terminal is in the normal working state mode, the terminal must ensure the service performance as much as possible, so that all the components of the terminal can work satisfactorily. In some extreme scenarios, the radio frequency receiving circuit of the terminal can be put into a power-saving working state, so...

Problems solved by technology

However, when the radio frequency receiving circuit of the terminal enters the power-saving working state mode, the performance loss of the radio frequency receiving circuit cannot be well controlled, and the degree of the loss is often unpredictable, so that the terminal cannot reach the balance between standby time and service performance. optimal tradeoff
