The present invention relates to the technical field of wireless communication, particularly relates to a method, system and apparatus for sending and receiving feedback information, to be used for transmitting the feedback information after the aggregation of carriers with different time division duplex (TDD) uplink and downlink configurations. The method of an embodiment of the present invention comprises: determining a dedicated feedback timing relationship by using a user equipment (UE) aggregating carriers with different TDD uplink/downlink configurations; the UE transmitting the feedback information corresponding to the downlink data on the primary carrier according to the determined dedicated feedback timing relationship. Because the feedback information can be transmitted after the aggregation of carriers with different TDD uplink and downlink configurations, thus the transmission efficiency and system performance after the aggregation of carriers with different TDD uplink and downlink configurations are improved.
