Abstract: Implementations in the application provide wearable devices. In an implementation, a wearable device includes a housing, a printed circuit board (PCB), a feeding unit, and a switch. The housing includes a metal portion configured as an antenna radiator. The PCB is disposed in the housing and disposed opposite to the metal portion. The feeding unit is electrically connected to a first end of the metal portion and feeds the antenna radiator. One end of the switch is electrically connected to a second end of the metal portion, and the other end of the switch is grounded. The switch has a first switch state or a second switch state, and an operating frequency band of the antenna radiator includes a first frequency band.

Abstract: An operation mode switching method and user equipment that relate to the field of communications technologies are disclosed, so that an operation mode of the user equipment can be automatically switched. A specific solution is: determining, by user equipment, that a current data transmission rate of the user equipment is less than a first rate threshold, and/or a battery temperature of the user equipment is greater than a first temperature threshold; determining, by the user equipment, that the user equipment is in a CA operation mode; changing, by the user equipment, a transmission mode parameter of the user equipment to a transmission mode parameter corresponding to a non-CA operation mode; and restarting, by the user equipment, a communications module of the user equipment, and sending a first access request to a base station, where the first access request carries the transmission mode parameter corresponding to the non-CA operation mode. Embodiments of the present invention are applied to a process in which the user equipment switches an operation mode of the user equipment.
