FIELD: wireless communication.
SUBSTANCE: invention relates to wireless communication and can be used to transmit information. In the information transmission method, the terminal receives the first signal information and the second signal information, while the first signal information is used to indicate the transmission configuration indication (TCI) state and the second signal information is used to initiate the first reference signal indicated in the TCI state. According to the first signal information, the terminal determines the planned target channel or target signal. The target channel or target signal planned by the first signal information uses the quasi-colocation information (QCL) corresponding to the first reference signal transmitted before the first character, or the QCL information corresponding to the second signal information transmitted before the first character.
EFFECT: increase in the flexibility and efficiency of the TCI.
