Abstract
Provided are a wireless communication method based on multiple-user multi-input multi-output (MU-MIMO) and a corresponding user equipment and eNode B. According to the present disclosure, a first MU-CQI offset corresponding to a first co-scheduled PMI which is fully orthogonal with a desired PMI is reported with a larger number of bits than a second MU-CQI offset corresponding to a second co-scheduled PMI which is not fully orthogonal with the desired PMI. Alternatively, a first MU-CQI off-set corresponding to a first co-scheduled PMI is reported with a first number of bits, and a second MU-CQI offset corresponding to a second co-scheduled PMI which is correlated with the first co-scheduled PMI is reported with a second smaller number of bits or even not reported. Alternatively, MU-CQI offset(s) corresponding to part of a plurality of co-scheduled PMIs configured by RRC is/are reported with a series of bits, wherein a first section of the series of bits indicates at least part of the co-scheduled PMI(s) for which the MU-CQI offset is reported, and a second section of the series of bits indicates the reported MU-CQI offset(s).
