Abstract: A method and apparatus for transmitting and receiving uplink control information. The method includes: determining a channel access type of an uplink control channel used for transmitting uplink control information by a terminal equipment; and detecting a channel according to the channel access type and transmitting the uplink control information to a network device after the channel is detected as being idle, or not detecting a channel according to the channel access type and transmitting the uplink control information to the network device.
