CHANNEL QUALITY INDICATOR FEEDBACK METHOD, RESOURCE SCHEDULING INFORMATION SENDING METHOD AND APPARATUSES

摘要

Embodiments of the present invention provide a method for feeding back a channel quality indicator, and a method and an apparatus for sending resource scheduling information. An apparatus for feeding back a channel quality indicator includes: a determining module, configured to determine a feedback granularity of a CQI according to a system bandwidth, a CQI feedback mode, and antenna port quantity information specified by a network device; and a feedback module, configured to feed back the CQI to the network device according to the feedback granularity of the CQI. The method for feeding back a channel quality indicator, and the method and the apparatus for sending resource scheduling information provided in the embodiments of the present invention are used to reduce system overheads.
