The embodiments of the present application provide a method and apparatus for transmitting information, said method comprising: a terminal device determines a first transmission means used in a first time unit for transmitting destination uplink information; said first transmission means is different from a second transmission means used in a second time unit for transmitting said destination uplink information, and the duration of the second time unit used for transmitting the destination uplink information is different from the duration of the first time unit used for transmitting the destination uplink information; the terminal device uses the first transmission means to send the destination uplink information to a network device. The information transmission method and apparatus improve flexibility in allocating time resources in a system and thus improving system performance.
