This application relates to information transmission by: determining, based on a quantity of bits of first information, a manner of generating second information, where the manner of generating the second information includes a first generation manner and a second generation manner, and in the first generation manner, a quantity of bits obtained after channel coding is determined based on a quantity of resource elements that carry the first information and that are on a first symbol of two symbols of a first physical uplink control channel; in the second generation manner, a quantity of bits obtained after channel coding is determined based on a quantity of resource elements that carry the first information and that are on two symbols of a second physical uplink control channel; and generating, in the manner of generating the second information, the second information carried on the two symbols. In the information transmission method in embodiments of this application, a reusing capability of a user and transmission performance can be improved.
