Abstract: This application discloses methods an apparatuses for sending and receiving uplink control information in the field of communications technology. In some implementations, a terminal device may receive first downlink control information (DCI) from a network device; determine, based on the received first DCI, that an uplink shared channel scheduled by using the first DCI is used to send only uplink control information (UCI); and send first UCI to the network device through the uplink shared channel scheduled by using the first DCI. In other words, the network device indicates to the terminal device by using DCI so that the terminal device can determine, based on an indication of the network device, whether the uplink shared channel scheduled by using the DCI is used to send only the UCI.
