Abstract

The invention discloses a power control method and device. The power control method is suitable for electronic equipment which can emit signals to uplink channels of different types. The power control method comprises the steps of acquiring emission power control signals, determining the channel types of the uplink channels where the electronic equipment are emitting signals, and carrying out back-off operation of different power on the uplink channels according to the channel types. Accordingly, in the power control method and device, when power control is conducted on all the uplink channels, a connecting establishing channel and other uplink channels can be differentiated, so that power back-off is conducted on the connecting establishing channel and the other uplink channels through different modes, and therefore good balance is achieved on the aspect of guaranteeing the health of a user and the aspect of achieving normal communication.

Description

technical field [0001] The present invention relates to the technical field of computers, and more specifically, the present invention relates to a power control method and a power control device. Background technique [0002] In recent years, electronic devices such as notebook computers, desktop computers, tablet computers (PADs), mobile phones, multimedia players, personal digital assistants (PDAs) and the like have become increasingly popular. Currently, most electronic devices support a wireless communication function for communicating with other devices such as base stations, access points, or peer devices and transferring various data by using different wireless access standards. [0003] When an electronic device is performing wireless communication, its transmission power in the uplink channel will become relatively large due to various reasons (for example, when using multiple wireless access standards to transmit data at the same time), which may exceed the electr...
