CHANNEL QUALITY INDICATOR (CQI) ESTIMATION METHOD AND APPARATUS

摘要

Disclosed are a channel quality indicator (CQI) estimation method and apparatus. The method comprises: detecting the channel state of an unlicensed carrier; when the channel state is an idle state, acquiring an interference measurement result of a cell on the unlicensed carrier of a designated slot; and according to the interference measurement result, acquiring an initial CQI estimation value for when the unlicensed carrier is occupied. By means of the present invention, the problem in the related art that a single measurement cannot meet a carrier switching requirement is solved, thereby improving the accuracy of CQI measurement.
