An operation mode switching method and user equipment 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.

Operation mode switching method and user equipment

A communications terminal includes a mainboard, a conductor bezel, a first conductor part, and a second conductor part, where a first location on the conductor bezel is electrically connected to a ground terminal on the mainboard, a second location on the conductor bezel is electrically connected to a ground terminal on the mainboard, the second conductor part is electrically connected to a fourth location on the conductor bezel, and a radio frequency port on the mainboard is electrically connected to a third location on the conductor bezel using the first conductor part; and the fourth location and the third location on the conductor bezel are between the first location and the second location. The communications terminal is conducive to reducing antenna assembly complexity and reducing manufacturing costs.

Communications terminal

The present disclosure discloses a tunable antenna and a terminal. The tunable antenna includes a circuit board, an antenna body configured to transmit and receive a signal of a first frequency band and including a feed end and a ground pin, where the feed end is disposed on the circuit board, and an electrical tuning network, where a ground point disposed on the circuit board is connected to the ground pin of the antenna body by using the electrical tuning network, and the electrical tuning network includes an inductor and a first tunable capacitor with a tunable capacitance value, where a load value of the inductor is changed by tuning a first capacitance value of the first tunable capacitor, so that a first effective electrical length of the antenna body is changed.
