A method, device and communication system for transmitting and receiving feedback information. The method includes: grouping multiple carriers according to the number of code block groups and / or transmission blocks; receiving the data sent by the network equipment on the multiple carriers and time units, and the downlink allocation index for configuring the feedback information sent on one or more carriers and time units; determining the feedback information corresponding to the carriers in each packet respectively And cascading the feedback information corresponding to each packet and sending it to the network device. Thus, not only the correct number of bits of feedback information can be reserved, but also the overhead of feedback information or DCI signaling can be reduced, so as to reduce or avoid the waste of resources.
