Abstract: Embodiments of the present invention provide an uplink subcarrier spacing indication method, a base station, and a terminal. The base station determines indication information that is used to indicate a first uplink subcarrier spacing supported by the base station, and communicates with the terminal according to the indication information. During the communication, the base station indicates the first uplink subcarrier spacing supported by the base station to the terminal, so that the terminal subsequently determines, based on the first uplink subcarrier spacing, a second uplink subcarrier spacing supported by the terminal; or the base station receives information that is sent by the terminal and that carries a second uplink subcarrier spacing, in other words, receives an indication from the terminal, so as to learn of the second uplink subcarrier spacing supported by the terminal or to be used by the terminal to send an uplink signal.

Abstract: Embodiments of the present invention provide a power control method and a terminal, so as to improve accuracy of transmit power used by the terminal during uplink transmission. The method includes: obtaining, by a first terminal, parameter information required for power control, where the parameter information includes at least one of a first parameter, a second parameter, and a third parameter; and determining, by the first terminal based on the parameter information, uplink transmit power used when uplink transmission is performed on a target beam or a target beam pair; where the first parameter includes a beam reception gain of a network device and/or a beam sending gain of the first terminal; the second parameter is used to indicate interference caused by a second terminal to the first terminal on the target beam; and the third parameter includes beam-specific target power and/or terminal-specific target power.
