Provided are methods and devices for determining a quasi-co-location (QCL) parameter, and the method comprises: receiving configuration information; and determining whether the configuration information satisfies a predetermined constraint condition, and determining an acquisition mode of a QCL parameter of a signal according to the determination result; in a case where the configuration information satisfies the constraint condition, determining the QCL parameter of the signal according to a first acquisition mode; in a case where the configuration information does not satisfy the constraint condition, determining the QCL parameter of the signal according to a second acquisition mode.
