Claim 17:
18. A channel quality indicator (CQI) feedback enhancement system, comprising a base station and a user equipment (UE), wherein
the base station is configured to send downlink traffic data to the UE, and receive, in a case where an error result is obtained by decoding the downlink traffic data by the UE, first information sent by the UE; and
the UE is configured to decode the downlink traffic data, and send the first information to the base station in the case where an error result is obtained by decoding the downlink traffic data, wherein the first information comprises a negative acknowledgement (NACK) instruction and an aperiodic CQI, or the first information comprises one NACK state of a plurality of NACK states and different NACK states correspond to different CQIs;
wherein a number of bits of the first information is denoted as b, wherein b is a positive integer; in the case where an error result is obtained by decoding the downlink traffic data, a resource position for the first information is determined based on the number b of bits of the first information and a physical uplink control channel (PUCCH) resource indicated by the base station.
