A base station provides downlink feedback information (DFI) to a user equipment (UE) in a wireless network. The base station generates hybrid automatic repeat request (HARQ) acknowledgment (HARQ-ACK)information in a downlink control information (DCI) payload for each HARQ process associated with uplink transmission from the UE to the base station. The base station sets a DFI flag in the DCI payload to a predetermined value. The base station generates error detection bits based on the DCI payload, and sends DCI to the UE. The DCI includes the DCI payload and the error detection bits scrambledwith a configured scheduling radio network temporary identifier (CS-RNTI). According to the invention, the DFI flag and the error detection bit scrambled by the CS-RNTI are utilized to enable the UE to distinguish the DCI, and the beneficial effect of reducing the receiving complexity of the UE is realized.
