Adaptive design method for LTE-Advanced reference signals

Abstract

In this paper, we presented a novel adaptive design method for LTE-A reference signals. Different reference signals mapping patterns display different performance at different environment such as low or high mobility and modulation rank. We proposed that different RS mapping pattern is chosen according to application environment of achieving the optimum performance of the system. The downlink reference signals were taken as an example to proof the novel method is effective by simulation performance.
