Evolution of Reference Signals for LTE-Advanced Systems

[rmwambu]

3GPP LTE Release 10 standards (also known as LTE-Advanced) adopted some of the state-of the- art radio access technologies that include carrier aggregation, eight-layer downlink spatial multiplexing, and four-layer uplink spatial multiplexing. For facilitating these enhancements, reference signals have significantly evolved in LTE-Advanced. This article examines underlying design principles of the LTE-Advanced reference signals.
