Based on the analysis of the current hybrid automatic repeat request (HARQ) mapping mechanism and the corresponding problems in LTE-Advanced system with carrier aggregation, this paper designs an improved HARQ mapping mechanism, in which an idea of semi-static mapping is introduced. The simulation results validate its effectiveness in improving system performance through the trade-off between diversity gain and overhead.
