Abstract: This application provides a power control method and a terminal device. The method includes: A terminal device receives N pieces of feedback information, where N is an integer greater than or equal to 1; and the terminal device determines a transmit power of the terminal device based on the N pieces of feedback information. In the foregoing technical solution, communication between terminal devices does not depend on a network device, and the terminal devices at two communication ends exchange information, so that transmit powers of the terminal devices are dynamically controlled. The technical solution may be applied to device-to-device communication, for example, V2X, LTE-V, V2V, the internet of vehicles, MTC, the IoT, LTE-M, M2M, and the internet of things.

Abstract: Embodiments of the present disclosure provide timing advance (TA) obtaining methods and apparatuses. One example method includes generating, by a base station, an indication message and sending the indication message to UE, and receiving, by the UE, the indication message sent by the base station. The UE can then obtain a TA of a second carrier based on the indication message, where the second carrier is a carrier not used to transmit a PUSCH. Although the second carrier is a carrier not used to transmit a PUSCH, the TA of the second carrier can still be obtained.
