Summary: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. Therefore, in this application, when determining that the preset data packet needs to be sent over the NR link, the terminal working in a DC mode increases the transmit power of the NR link, to ensure as much as possible that there is sufficient transmit power for sending the preset data packet. This avoids retransmission.
