What is new in LTE? New radio transmission schemes:OFDMA in downlinkSC-FDMA in uplinkMIMO Multiple Antenna TechnologyOFDM Modulation Mapper (QPSK, 16QAM, 64QAM)
New radio protocol architecture:Complexity reductionFocus on shared channel operation
New network architecture: flat architectureMore functionality in the base station (eNodeB)Focus on packet switched domain
Important for Radio Planning:Frequency Reuse 1No need for Frequency PlanningImportance of interference controlLTE requires Physical Layer Cell Identity (PCI) planning (504 physical layer cell IDs organised into 168 groups of 3)Additional areas need to be planned like PUCCH and PDCCH capacity.Tracking Area Planning needed.
