Abstract: This application discloses example methods and apparatuses for information transmission. One example method includes receiving, by a terminal device, downlink control information that includes first information used to indicate a symbol that carries uplink control information. The terminal device can then determine, based on the first information, the symbol that carries the uplink control information, and can map the uplink control information to the symbol that carries the uplink control information. The terminal device then sends the uplink control information to a network device.
