Claim 4:
5. The method according to claim 4, wherein the determining two pieces of QCL information based on at least one of the following parameters comprises: when it is determined that the parameter meets at least one of the following conditions, determining two pieces of QCL information, wherein:
the QCL configuration information of the terminal device comprises a spatial QCL parameter or comprises a QCL type D;
the quantity of SSBs transmitted by the network device in N time units is greater than or equal to a first threshold, and N is a positive integer;
the obtained subcarrier spacing is greater than or equal to a second threshold;
the transmission mode of the terminal device is a second transmission mode, wherein the second transmission mode comprises one of coordinated transmission, dynamic point selection DPS transmission, or non-coherent joint transmission NCJT;
the DCI format is a second format, wherein the second format is a DCI format used in the second transmission mode;
the quantity of bits of the DCI is greater than or equal to a third threshold;
the obtained DCI comprises a specific field, or a value of the specific field of the obtained DCI belongs to a specific range;
the quantity of pieces of indication information that is supported by the terminal device and that is used to indicate the QCL information of the antenna port of the reference signal is at least two;
the quantity of RS sets associated with the indication information that is supported by the terminal device and that is used to indicate the QCL information of the antenna port of the reference signal is at least two;
the maximum quantity of pieces of DCI that needs to be detected is greater than 1;
the maximum quantity of pieces of DCI that can be detected by the terminal device is greater than 1;
the quantity of panels supported by the terminal device is greater than 1; and
the data transmission scenario is that the quantity of pieces of QCL information cannot be determined, or it is determined that the quantity of pieces of QCL information is greater than 1.
