Abstract: A transmit power adjustment method, apparatus, and a system. The system is configured for obtaining a first distance between a first antenna and a second antenna, determining a first transmit power of the first antenna, and a second transmit power of the second antenna, wherein, when the first distance is greater than a first value, the first transmit power is at or below a first limit power, and the second transmit power is at or below a second limit power, or wherein, when the first distance is less than the first value, a sum of a first exposure ratio of the first transmit power and a second exposure ratio of the second transmit power is less than or equal to 1, and transmitting, a signal at the first transmit power through the first antenna and a signal at the second transmit power through the second antenna.

Abstract: A transmit power control method includes obtaining an uplink-downlink configuration (uplink (UL)/downlink (DL) assignment) from a network side and determining a power decrease that can be reduced in the uplink-downlink configuration compared with that in an all-uplink configuration when and uplink time proportion configured in the uplink-downlink configuration is not 100% and the uplink-downlink configuration is not the all-uplink configuration.

Abstract: A sensor adjustment method includes obtaining a folding status parameter, where the folding status parameter is used to describe a folding extent of a foldable device, and where a component of the foldable device in a folded state causes interference to a first sensor of the foldable device compared with a non-folded state; invoking a sensor adjustment corresponding to the folding status parameter; and adjusting a sensor operating parameter of the first sensor according to the sensor adjustment and/or performing data preprocessing on first sensor data collected by the first sensor.
