摘要: The commercial deployment of LTE Release 8 is gaining significant momentum all over the globe, and evolving to LTE-Advanced, which offers various new features meet or exceed IMT-Advanced requirements. Since LTE-Advanced targets ambitious spectral efficiency peak throughput, it poses tremendous system design challenges operators manufacturers, especially for mobile terminals. This article discusses modem issues related carrier aggregation, enhanced ICIC HetNet, detection eight-layer transmission, reference signals multi-antenna support, HARQ buffer management. We provide an overview technical sketch perspectives tackling them exploit full benefits system.
