Abstract: This application provides a method for dynamically switching antennas. User equipment determines an antenna switching sequence based on a networking mode of the user equipment and an actual scenario, and performs antenna switching based on the determined antenna switching sequence. When the technical solutions of this application are implemented, a problem that a conflict exists in an antenna switching process is effectively resolved without adding hardware.

Abstract: This application provides a transmit power control method, a terminal, a chip system, and a system. The method includes: A terminal connects to a 4G network device over an LTE link and connects to a 5G network device over an NR link, where transmit power of the NR link is first transmit power; determines to send a first data packet over the NR link, where the first data packet is a preset data packet; adjusts the first transmit power to second transmit power, where the second transmit power is greater than the first transmit power; and sends the first data packet at the second transmit power over the NR link.

Abstract: This application provides example methods for controlling an output power of an antenna for user equipment. One example method includes, during a sounding reference signal (SRS) transmission period, transmitting, by a first antenna of at least one antenna of the user equipment, a first SRS signal to a base station at a first SRS output power, where the first SRS output power is equal to a maximum output power (Pcmax) of the first antenna. During the SRS period, a non-SRS signal is transmitted to the base station at a non-SRS output power, where the non-SRS output power is less than a difference between the maximum output power of the first antenna and a maximum output power reduction of the first antenna, and the maximum output power reduction of the first antenna is set to meet an electromagnetic power density exposure requirement of the first antenna.

Abstract: An in-device coexistence (IDC) indication message sending method includes a network device determining, when configuration information sent by the network device indicates that the terminal device can send an IDC indication message, a most proper IDC interference cancellation manner based on SUL frequency information, a type of an interfering frequency, a transmit power of the terminal device, a transmit power of the network device, a priority of a frequency band in which the interfering frequency is located, or an IDC interference cancellation manner expected by the terminal device that are indicated by the IDC indication message sent by the terminal device.
