1. A terminal device, comprising:
at least one processor; and
at least one memory including computer program codes, wherein the at least one memory and the computer program codes are configured to, with the at least one processor, cause the terminal device to:
receive a quasi-co-location, QCL, source configuration from a network device, wherein the QCL source configuration indicates at least two transmission configuration indication, TCI, states that indicate reference signals from valid QCL sources for a coherent joint transmission, CJT, of tracking reference signals, TRSs;
perform a QCL property estimation on received TRSs based on the QCL source configuration; and
receive a TRS resource configuration for the QCL property estimation of the CJT, wherein the TRS resource configuration is received in downlink control information, DCI, message, and indicates one or both of an identity of a NZP CSI-RS resource set or an identity of a NZP CSI-RS resource.
