Research on FDM Based DRS Pattern for Dual-layer Beamforming in LTE System
To enable efficient demodulation for dual-layer beam forming in LTE system, this paper studied the frequency division multiplexing (FDM) based demodulation reference signal (DRS) pattern for normal subframe with normal cyclic prefix (CP). From the view of DRS multiplexing method, DRS overhead and DRS location, the DRS pattern design was analyzed in detail. Based on the analysis, a novel method with overhead of 12 DRS per physical resource block (PRB) and placing the DRS on the edge of each PRB was proposed. The link level simulation results showed that the pattern designed with this method provided the best performance of throughput in most of occasions among the candidate patterns.
