1. A quasi co-location (QCL) indication method applied to coordinated multistation transmission, the method comprising:
receiving, by a communication apparatus, N transmission configuration indication (TCI) states, wherein each TCI state of the N TCI states indicates a QCL configuration information of a demodulation reference signal (DMRS), wherein the QCL configuration information indicates a tracking reference signal (TRS), time-frequency spread information associated with the TRS and delay-frequency offset information associated with the TRS, delay-frequency offset information indicated by QCL configuration information of M TCI states of the N TCI states is applicable to delay-frequency offset information indicated by QCL configuration information of N-M TCI states, N DMRS ports indicated by the N TCI states are the same, N is greater than or equal to 2, and M is greater than or equal to 1; and
determining, by the communication apparatus, based on the N TCI states, QCL information of N DMRS.
