1. An information transmission method, comprising:
receiving, by a terminal, first signaling and second signaling,
wherein the first signaling is configured for indicating a transmission configuration indication (TCI) state, and the second signaling is configured for triggering a first reference signal indicated in the TCI state; and
determining, by the terminal according to the first signaling, a target channel or a target signal scheduled by the first signaling,
wherein the target channel or the target signal scheduled by the first signaling uses quasi-co-location (QCL) information corresponding to the first reference signal transmitted before a first symbol or QCL information corresponding to the second signaling transmitted before a first symbol,
wherein the first symbol comprises at least one of:
a first time domain symbol occupied by the first signaling;
a first time domain symbol occupied by a physical channel where the first signaling is located;
an N1-th time domain symbol before the target channel or the target signal scheduled by the first signaling, wherein N1 is a positive integer;
an N2-th time domain symbol before the first signaling, wherein N2 is a positive integer; or
an N2-th time domain symbol before a physical channel where the first signaling is located, wherein N2 is a positive integer.
