Abstract
A method and base station for coordinated multi point data transmission are disclosed. The method includes: a base station receiving a per-cell CQI value reported by a UE; looking up an SINR-CQI mapping table according to the per-cell CQI value, and acquiring a subband/broadband SINR value; performing CQI recalculation according to the subband/broadband SINR value, and acquiring a recalculated subband/broadband CQI value; and selecting modulation and coding according to the recalculated subband/broadband CQI value to schedule data transmission. With the method and base station of the embodiments of the present document, in a CoMP system, in a joint transmission scenario, the accuracy of the CQI value used by the BS for scheduling is improved, and the oscillation during an AMC process is reduced.
