Abstract

A method and base station for jointly adjusting downlink AMC and MIMO modes. The base station comprises an AMC module, a fast feedback module and a joint adjustment module. The method comprises: a base station determining the current maximum available Downlink Interval Usage Code (DIUC) using a downlink Carrier to Interference plus Noise ratio (CINR) fed back by a terminal, using a MIMO mode fed back by the terminal to determine the current channel condition, and jointly adjusting the current MIMO mode and the DIUC of the terminal within the maximum available DIUC range according to the current channel condition. The method and base station overcome the shortcoming of adjusting MIMO modes or DIUCs separately, and provide more combinations of the MIMO modes and DIUCs to maximize spectral utilization and data transmission rate, thereby achieving ultimately the purpose of improving link reliability and system throughput.
