1. A channel quality indicator (CQI) feedback enhancement method, comprising:
decoding downlink traffic data upon receiving the downlink traffic data sent by a base station; and
sending first information to the base station in a 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.
