OFDMA/MIMO = Better Performance Higher throughput Less susceptible to interference OFDM works by splitting the radio signal into multiple smaller sub-signals that are then transmitted simultaneously at different frequencies to the receiver. OFDM reduces the amount of crosstalk in signal transmissions. 802.11a WLAN, 802.16 and WiMAX technologies use OFDM. Orthogonal Frequency Division – Multiple Access(OFDMA) Improves radio link performance
Allows larger delay spread Eliminates inter-symbol interference

CSI - For downlink channel sounding / Sparse, low overhead (configurable)
CSI = PMI(precoding matrix indicator) + RI(rank indicator) + CQI (channel quality indicator)
DM - UE-specific DM-RS, which is precoded, makes it possible to apply non-codebook-based precoding (precoding based on CSI feedback and/or UL sounding)
− UE-specific DM-RS will enable application of enhanced multi-user beamformingsuch as zero forcing (ZF) for, e.g., 4-by-2 MIMO
− DM RS pattern for higher numbers of layers is extended for 2-layer format for transmission mode 8 in Rel-9 //CDM between RS of two layers// E.g. for 4 antenna ports:

Physical Multicast Channel (PMCH) is used instead of PDSCH.
Special RS pattern with higher density in frequency domain supports longer “delay spread”
from multi-cell transmission.
Multimedia Broadcast Single Frequency Network (MBSFN) mode of operation is supported by E‐UTRAN to enable efficient multi‐cell transmission of E‐MBMS services

Coordinated scheduling/beamforming (CS/CB)
• PDSCH transmitted only from 1 cell; scheduling/beamforming is coordinated among cells

Joint transmission (JT): PDSCH is transmitted from multiple cells with precoding using DMRS among coordinated cells
Dynamic cell selection: PDSCH is transmitted from one cell, which is dynamically selected
