1. A method performed by a base station, the method comprising:
transmitting, to a terminal device, first information indicating a first resource set for a Channel State Information Reference Signal (CSI-RS) for tracking, the first information comprising:
a parameter trs-Info set to a value representing true; and
a first parameter indicating a first time offset between
a first slot containing a first signal that triggers a transmission of the CSI-RS for tracking and
a second slot in which the CSI-RS for tracking is transmitted,
wherein the first time offset is configured to satisfy a threshold condition required by the terminal device; and
transmitting the CSI-RS for tracking to the terminal device in the second slot.
