Patent attributes
Embodiments of this application disclose an information transmission method and apparatus, and relate to the field of communications technologies. In this technical solution, impact of a beam on information transmission is taken into account, thereby improving robustness of a control channel. The method may include: performing rate matching on a first bit sequence based on beam indication information, to obtain a second bit sequence, where the first bit sequence is a bit sequence obtained by performing channel coding on an original bit sequence; mapping the second bit sequence onto a time-frequency resource; and sending, to a receive end by using a beam indicated by the beam indication information, the second bit sequence that is mapped onto the time-frequency resource.
