1. A method for measuring a measurement reference signal performed by a user equipment (UE), comprising:
determining reference signal measurement information using transmission configuration indication (TCI) codepoint information, wherein the TCI codepoint information is indicated in a TCI field in a physical downlink control channel (PDCCH) received by the UE, wherein the reference signal measurement information includes a TCI codepoint index;
determining a measurement reference signal resource in a measurement reference signal resource set according to the TCI codepoint index; and
measuring the measurement reference signal,
wherein, in a case that a number of multiple TCI states included in the TCI codepoint index is greater than one, a quasi co-location (QCL) reference signal in the measurement reference signal resource includes an associated QCL reference signal resource associated with a predefined TCI state in the multiple TCI states included in the TCI codepoint index.
