1. A method for determining a search space parameter, applied to a terminal device, wherein the method comprises:
receiving dedicated signaling, wherein the dedicated signaling is used to configure a transmission configuration indication state (TCI) state of a control resource set (CORESET #0) for the terminal device, and a quasi-colocation (QCL) source reference signal Source (RS) indicated by the TCI state of the CORESET #0 is a channel state information reference signal (CSI-RS);
determining a target synchronization signal block (SSB) having a first association relationship with the CSI-RS wherein the first association relationship is that the CSI-RS is in QCL with the target SSB; and
determining parameter information of a search space #0 in the CORESET #0 based on the target SSB;
wherein the parameter information of the search space #0 comprises time-frequency resource information.
