1. A method comprising:
obtaining, by an apparatus, information of a reference signal (RS) relationship between an RS and a physical uplink (UL) channel;
obtaining, by the apparatus, a power control set associated with the RS relationship, wherein the power control set includes a target power, a downlink (DL) RS for path-loss estimation, and a factor of a transmit power command;
determining, by the apparatus, according to the RS relationship, a value of the target power, a value of the path-loss estimation corresponding to the DL RS, and a value of the transmit power command; and
determining, by the apparatus, a transmit power for transmitting the physical UL channel based on the value of the target power, the value of the path-loss estimation and the value of the transmit power command.
