Abstract
Embodiments of the present invention provide a channel quality indicator feedback method and apparatus, and a user equipment, so as to improve accuracy of channel quality reflection. The method includes: acquiring a first channel quality indicator CQIbased on detection of a pilot that is sent by a base station; acquiring a second channel quality indicator CQIbased on a result of detection of a demodulation pilot; and sending the first channel quality indicator CQIand/or the second channel quality indicator CQIto the base station in a manner in which the base station can distinguish the first channel quality indicator CQIand/or the second channel quality indicator CQI. The method provided by the embodiments of the present invention objectively reflects a current channel quality status, so that the base station can acquire accurate channel quality information, thereby objectively scheduling data based on the channel quality information and improving data sending efficiency of a channel.
