Abstract:
The invention provides a downlink data feedback method, equipment, and system. The method comprises: performing, by user equipment (UE), a cyclic redundancy check (CRC) and an error estimating coding (EEC) check on each of media access control (MAC) protocol data units (PDU) to determine a feedback type of each of the MAC PDUs and a feedback result corresponding to the feedback type; transmitting, by the UE, feedback information comprising the feedback type and feedback result of each of the MAC PDUs to a base station; and obtaining, by the base station, according to the feedback information, the feedback type and feedback result of each of the MAC PDUs. The embodiment enables a UE to determine feedback information comprising a feedback type and a feedback result, and transmit the feedback information to a base station, realizing downlink data feedback from the UE to the base station according to a CRC check result and an EEC check result.
