Abstract
The present disclosure relates to communication methods and communications apparatus. One example method includes determining a plurality of frequency domain units on which reporting of a precoding matrix indicator (PMI) is based in reporting bandwidth. The plurality of frequency domain units include one or more first frequency domain units and third frequency domain units obtained by dividing one or more second frequency domain units. A granularity of the first frequency domain unit is less than a preconfigured first granularity, a granularity of the second frequency domain unit is a first granularity, and a granularity of the third frequency domain unit is a predetermined second granularity. The first granularity is a granularity preconfigured for reporting a channel quality indicator (CQI), a second granularity is a granularity predetermined for reporting the PMI, and the second granularity is less than the first granularity.
