1. A power control parameter configuration method, comprising:
obtaining, by a terminal, a Quasi Co-Location (QCL) relationship indicated by a network side device for an uplink signal;
determining, by the terminal, (i) a power control parameter corresponding to the QCL relationship, or (ii) a power control parameter and a path loss reference signal both corresponding to the QCL relationship; and
determining, by the terminal, uplink transmission power in accordance with the power control parameter, or, determining, by the terminal, uplink transmission power in accordance with both the power control parameter and the path loss reference signal, and transmitting the uplink signal in accordance with the uplink transmission power,
wherein the power control parameter comprises at least one of a path loss compensation factor or a target received power,
wherein the power control parameter is a power control parameter carried in configuration information for the QCL relationship; or the power control parameter is a power control parameter obtained through performing a first operation on the power control parameter in the configuration information for the QCL relationship and a power control parameter stored in the terminal.
