Abstract:
Methods and apparatus for multiplexing reference signals for Multiple Input Multiple Output (MIMO) layers are provided. Resources for Demodulation Reference Signals (DMRS) corresponding to each of two or more data streams are assigned, wherein the resources assigned to each of the data streams are staggered in frequency and span two or more OFDM (Orthogonal Frequency Divisional Multiplexing) symbols. The DMRS is transmitted using the assigned resources.
