The invention provides a feedback data acceptance state method applied to a long term evolution-advanced (LEV-A) system. The feedback data acceptance state method includes: A, user end (UE) sorts downlink subframes of transmitter data aiming at each component carrier (CC); B, aiming at each CC, generating acceptance state feedback information of X prior downlink subframes according to sorting results of procedure A, wherein X<=M, M is the number of the downlink subframes on each CC; C, sending generated acceptance state feedback information aiming at each CC to a base station. The feedback data acceptance state method can ensure the UE does not explain the acceptance state of the downlink sub-frames right if acceptance and acceptance feedback between base stations are inconsistent and does not influence transmission of hybrid automatic repeat request (HARQ), and saves unlink cost occupied by the acceptance state feedback information and enlarges unlink coverage range.
