CHANNEL QUALITY INDICATOR FEEDBACK METHOD AND APPARATUS, AND USER EQUIPMENT

摘要

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 CQI1 based on detection of a pilot that is sent by a base station; acquiring a second channel quality indicator CQI2 based on a result of detection of a demodulation pilot; and sending the first channel quality indicator CQI1 and/or the second channel quality indicator CQI2 to the base station in a manner in which the base station can distinguish the first channel quality indicator CQI1 and/or the second channel quality indicator CQI2. 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.
