An information transmission method, comprising: receiving, by a terminal, first signaling and second signaling, wherein the first signaling comprises a transmission configuration indication, TCI, state and information used for scheduling a target channel or a target signal, 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. receiving, by a terminal, first signaling and second signaling, wherein the first signaling comprises a transmission configuration indication, TCI, state and information used for scheduling a target channel or a target signal, 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. 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.
