1. An open-loop power control method, comprising:
receiving, by a terminal, transmitted power configuration information, wherein the transmitted power configuration information comprises a first path loss compensation factor and a second path loss compensation factor;
determining, by the terminal, a target path loss compensation factor based on the transmitted power configuration information, wherein the target path loss compensation factor is one of the first path loss compensation factor and the second path loss compensation factor; and
controlling, by the terminal, a transmitted power of the terminal based on the target path loss compensation factor;
wherein determining, by the terminal, the target path loss compensation factor based on the transmitted power configuration information comprises:
determining, by the terminal, the target path loss compensation factor based on the transmitted power configuration information and a path loss value measured by the terminal;
or
determining, by the terminal, the target path loss compensation factor based on the transmitted power configuration information and a type of a reference signal, wherein the reference signal is used to determine a path loss value between the terminal and an access network device;
or
determining, by the terminal, the target path loss compensation factor based on the transmitted power configuration information and a type/types of a channel/signal through which the terminal transmits data.
