Abstract: Disclosed are a method and a device for sending and receiving acknowledgement feedback information, which relate to the field of wireless communications, and are applicable to solving the problem of transmitting acknowledgement feedback information of downlink data in the case of aggregation of a time division duplex (TDD) carrier and a frequency division duplex (FDD) carrier. In this solution, a terminal receives configuration signaling sent by a network side, where the configuration signaling instructs to divide M downlink carriers for carrier aggregation into information about N downlink carrier groups, and to configure one uplink carrier for each downlink carrier group; the uplink carrier used for sending acknowledgement feedback information corresponding to downlink data is determined according to the configuration signaling, and the acknowledgement feedback information corresponding to the downlink data is sent to the network side according to a determination result after the downlink data is received. This application solves the problem of how to receive acknowledgement feedback information in the case of aggregation of the TDD carrier and the FDD carrier.
