Abstract
The disclosure provides a downlink transmission method for a Multiple Input Multiple Output (MIMO) system, and a base station, wherein the method comprises: a base station selecting a downlink MIMO mode in a downlink transmission mode in which a UE currently is by using a Channel Quality Indicator (CQI), a Rank Indicator (RI) and a Preceding Matrix Indicator (PMI) which are reported by the UE within a time window; and the base station transmitting data to the UE by using the selected downlink MIMO mode. The disclosure achieves the effect of increasing the coverage and capacity of the LTE system to the maximum.
